-
-DPI hasn't really been used up until now, so the default has
-been meaningless.
-In theory we should be able to pass the desired format for the
-adjacent bridge chip through, but framework seems to be missing
-for that.
-
-As the main device to use DPI is the VGA666 or Adafruit Kippah,
-both of which use RGB666, change the default to being RGB666 instead
-of RGB888.

-Subject: [PATCH] drm/vc4: Fix timings for VEC modes
-
-This commit fixes vertical timings of the VEC (composite output) modes
-to accurately represent the 525-line ("NTSC") and 625-line ("PAL") ITU-R
-standards.
-
-Previous timings were actually defined as 502 and 601 lines, resulting
-in non-standard 62.69 Hz and 52 Hz signals being generated,
-respectively.
-
-Changes to vc4_crtc.c have also been made, to make the PixelValve
-vertical timings accurately correspond to the DRM modeline in interlaced
-modes. The resulting VERTA/VERTB register values have been verified
-against the reference values set by the Raspberry Pi firmware.

-
-PAL-M is a Brazilian analog TV standard that uses a PAL-style chroma
-subcarrier at 3.575611[888111] MHz on top of 525-line (480i60) timings.
-This commit makes the driver actually use the proper VEC preset for this
-mode instead of just changing PAL subcarrier frequency.
-
-DRM mode constant names have also been changed, as they no longer
-correspond to the "NTSC" or "PAL" terms.

-Subject: [PATCH] drm/vc4: Add support for more analog TV standards
-
-Add support for the following composite output modes (all of them are
-somewhat more obscure than the previously defined ones):
-
-- NTSC_443 - NTSC-style signal with the chroma subcarrier shifted to
- 4.43361875 MHz (the PAL subcarrier frequency). Never used for
- broadcasting, but sometimes used as a hack to play NTSC content in PAL
- regions (e.g. on VCRs).
-- PAL_N - PAL with alternative chroma subcarrier frequency,
- 3.58205625 MHz. Used as a broadcast standard in Argentina, Paraguay
- and Uruguay to fit 576i50 with colour in 6 MHz channel raster.
-- PAL60 - 480i60 signal with PAL-style color at normal European PAL
- frequency. Another non-standard, non-broadcast mode, used in similar
- contexts as NTSC_443. Some displays support one but not the other.
-- SECAM - French frequency-modulated analog color standard; also have
- been broadcast in Eastern Europe and various parts of Africa and Asia.
- Uses the same 576i50 timings as PAL.
-
-Also added some comments explaining color subcarrier frequency
-registers.

-Subject: [PATCH] drm/vc4: Allow setting the TV norm via module
- parameter
-
-Similar to the ch7006 and nouveau drivers, introduce a "tv_mode" module
-parameter that allow setting the TV norm by specifying vc4.tv_norm= on
-the kernel command line.
-
-If that is not specified, try inferring one of the most popular norms
-(PAL or NTSC) from the video mode specified on the command line. On
-Raspberry Pis, this causes the most common cases of the sdtv_mode
-setting in config.txt to be respected.

-Subject: [PATCH] drm/vc4: Refactor mode checking logic
-
-Replace drm_encoder_helper_funcs::atomic_check with
-drm_connector_helper_funcs::atomic_check - the former is not called
-during drm_mode_obj_set_property_ioctl(). Set crtc_state->mode_changed
-if TV norm changes even without explicit mode change. This makes things
-like "xrandr --output Composite-1 --set mode PAL-M" work properly.

-
-This is a squash of all firmware-kms related patches from previous
-branches, up to and including
-"drm/vc4: Set the possible crtcs mask correctly for planes with FKMS"
-plus a couple of minor fixups for the 5.9 branch.
-Please refer to earlier branches for full history.
-
-This patch includes work by Eric Anholt, James Hughes, Phil Elwell,
-Dave Stevenson, Dom Cobley, and Jonathon Bell.

-
-drm/vc4: Fixup firmware-kms after "drm/atomic: Pass the full state to CRTC atomic enable/disable"
-
-Prototype for those calls changed, so amend fkms (which isn't
-upstream) to match.

-
-drm/vc4: Make normalize_zpos conditional on using fkms
-
-Eric's view was that there was no point in having zpos
-support on vc4 as all the planes had the same functionality.
-
-Can be later squashed into (and fixes):
-drm/vc4: Add firmware-kms mode

-
-drm/vc4: FKMS: Change of Broadcast RGB mode needs a mode change
-
-The Broadcast RGB (aka HDMI limited/full range) property is only
-notified to the firmware on mode change, so this needs to be
-signalled when set.

-From: Dave Stevenson <dave.stevenson@raspberrypi.com>
-Date: Tue, 27 Apr 2021 14:24:21 +0200
-Subject: [PATCH] drm/vc4: Add support for gamma on BCM2711
-
-BCM2711 changes from a 256 entry lookup table to a 16 point
-piecewise linear function as the pipeline bitdepth has increased
-to make a LUT unwieldy.
-
-Implement a simple conversion from a 256 entry LUT that userspace
-is likely to expect to 16 evenly spread points in the PWL. This
-could be improved with curve fitting at a later date.

-Subject: [PATCH] drm/vc4: hvs: Force modeset on gamma lut change
-
-The HVS Gamma block can only be updated when idle, so we need to disable
-the HVS channel when the gamma property is set in an atomic commit.
-
-Since the pixelvalve cannot have its assigned channel halted without
-stalling unless it's disabled as well, in our case that means forcing a
-full disable / enable cycle on the pipeline.

-Subject: [PATCH] drm/vc4: Enable gamma block only when required.
-
-With HVS5 the gamma block is now only reprogrammed with
-a disable/enable. Loading the table from vc4_hvs_init_channel
-(called from vc4_hvs_atomic_enable) appears to be at an
-invalid point in time and so isn't applied.
-
-Switch to enabling and disabling the gamma table instead. This
-isn't safe if the pipeline is running, but it isn't now.
-For HVS4 it is safe to enable and disable dynamically, so
-adopt that approach there too.

-Subject: [PATCH] drm/panel: Add and initialise an orientation field to
- drm_panel
-
-Current usage of drm_connector_set_panel_orientation is from a panel's
-get_modes call. However if the panel orientation property doesn't
-exist on the connector at this point, then drm_mode_object triggers
-WARNs as the connector is already registered.
-
-Add an orientation variable to struct drm_panel and initialise it from
-drm_panel_init.
-panel_bridge_attach can then create the property before the connector
-is registered.

-Subject: [PATCH] drm/vc4: Convert vc4_dsi to using a bridge instead of
- encoder.
-
-Remove the encoder functions, and create a bridge attached to
-this dumb encoder which implements the same functionality.
-
-As a bridge has state which an encoder doesn't, we need to
-add the state management functions as well.
-
-As there is no bridge atomic_mode_set, move the initialisation
-code that was in mode_set into _pre_enable.
-The code to actually enable and disable sending video are split
-from the general control into _enable and _disable.

-Subject: [PATCH] drm/vc4: Remove entry to ULPS from vc4_dsi
- post_disable
-
-Post_disable was sending the D-PHY sequence to put any device
-into ULPS suspend mode, and then cutting power to the DSI block.
-The power-on reset state of the DSI block is for DSI to be in
-an operational state, not ULPS, so it then never sent the sequence
-for exiting ULPS. Any attached device that didn't have an external
-reset therefore remained in ULPS / standby, and didn't function.
-
-Use of ULPS isn't well specified in DRM, therefore remove entering
-it to avoid the above situation.

-Subject: [PATCH] drm/vc4: hdmi: Add CSC for BT601/709/2020 limited and
- full range output
-
-The HVS always composes in the RGB domain, but there is a colourspace
-conversion block on the output to allow for sending YCbCr over the
-HDMI interface.
-The colourspace on that link is configurable via the "Colorspace"
-property on the connector, and that updates the infoframes. There
-is also selection of limited or full range based on the mode selected
-or an override.
-
-Add code to update the CSC as well so that the metadata matches the
-image data.

-
-The stuff never really worked, and leads to lots of fun because it
-out-of-order frees atomic states. Which upsets KASAN, among other
-things.
-
-For async updates we now have a more solid solution with the
-->atomic_async_check and ->atomic_async_commit hooks. Support for that
-for msm and vc4 landed. nouveau and i915 have their own commit
-routines, doing something similar.
-
-For everyone else it's probably better to remove the use-after-free
-bug, and encourage folks to use the async support instead. The
-affected drivers which register a legacy cursor plane and don't either
-use the new async stuff or their own commit routine are: amdgpu,
-atmel, mediatek, qxl, rockchip, sti, sun4i, tegra, virtio, and vmwgfx.
-
-Inspired by an amdgpu bug report.
-
-v2: Drop RFC, I think with amdgpu converted over to use

- drm/amd/display: Add fast path for cursor plane updates
-
-we don't have any driver anymore where we have userspace expecting
-solid legacy cursor support _and_ they are using the atomic helpers in
-their fully glory. So we can retire this.
-
-v3: Paper over msm and i915 regression. The complete_all is the only
-thing missing afaict.
-
-v4: Rebased on recent kernel, added extra link for vc4 bug.

-Subject: [PATCH] drm/atomic: If margins are updated, update all
- planes.
-
-Margins may be implemented by scaling the planes, but as there
-is no way of intercepting the set_property for a standard property,
-and all planes are checked in drm_atomic_check_only before the
-connectors, there's now way to add the planes into the state
-from the driver.
-
-If the margin properties change, add all corresponding planes to
-the state.

-Subject: [PATCH] drm/vc4: Add async update support for cursor planes
-
-Now that cursors are implemented as regular planes, all cursor
-movements result in atomic updates. As the firmware-kms driver
-doesn't support asynchronous updates, these are synchronous, which
-limits the update rate to the screen refresh rate. Xorg seems unaware
-of this (or at least of the effect of this), because if the mouse is
-configured with a higher update rate than the screen then continuous
-mouse movement results in an increasing backlog of mouse events -
-cue extreme lag.
-
-Add minimal support for asynchronous updates - limited to cursor
-planes - to eliminate the lag.
-
-See: https://github.com/raspberrypi/linux/pull/4971

-

-Until now the vc4 driver has been relying on the firmware to
-have set these to sensible values.
-
-In testing triple screen support it has been noted that only

-Subject: [PATCH] BCM2708: Add core Device Tree support
-MIME-Version: 1.0
-Content-Type: text/plain; charset=UTF-8
-Content-Transfer-Encoding: 8bit
-
-Add the bare minimum needed to boot BCM2708 from a Device Tree.

-BCM2708: DT: change 'axi' nodename to 'soc'
-
-Change DT node named 'axi' to 'soc' so it matches ARCH_BCM2835.
-The VC4 bootloader fills in certain properties in the 'axi' subtree,
-but since this is part of an upstreaming effort, the name is changed.
-

-
-BCM2708_DT: Correct length of the peripheral space
-
-Use dts-dirs feature for overlays.
-
-The kernel makefiles have a dts-dirs target that is for vendor subdirectories.
-
-Using this fixes the install_dtbs target, which previously did not install the overlays.

-
-BCM270X_DT: switch to bcm2835-i2s
-
-I2S soundcard drivers with proper devicetree support (i.e. not linking
-to the cpu_dai/platform via name but to cpu/platform via of_node)
-will work out of the box without any modifications.
-
-When the kernel is compiled without devicetree support the platform
-code will instantiate the bcm2708-i2s driver and I2S soundcard drivers
-will link to it via name, as before.

-BCM270X_DT: Make mmc overlay compatible with current firmware
-
-The original DT overlay logic followed a merge-then-patch procedure,
-i.e. parameters are applied to the loaded overlay before the overlay
-is merged into the base DTB. This sequence has been changed to
-patch-then-merge, in order to support parameterised node names, and
-to protect against bad overlays. As a result, overrides (parameters)
-must only target labels in the overlay, but the overlay can obviously target nodes in the base DTB.
-
-mmc-overlay.dts (that switches back to the original mmc sdcard
-driver) is the only overlay violating that rule, and this patch
-fixes it.
-
-bcm270x_dt: Use the sdhost MMC controller by default
-
-The "mmc" overlay reverts to using the other controller.
-
-squash: Add cprman to dt
-
-BCM270X_DT: Use clk_core for I2C interfaces
-
-BCM270X_DT: Use bcm283x.dtsi, bcm2835.dtsi and bcm2836.dtsi
-
-The mainline Device Tree files are quite close to downstream now.
-Let's use bcm283x.dtsi, bcm2835.dtsi and bcm2836.dtsi as base files
-for our dts files.
-
-Mainline dts files are based on these files:
-
- bcm2835-rpi.dtsi
- bcm2835.dtsi bcm2836.dtsi
- bcm283x.dtsi
-
-Current downstream are based on these:
-
- bcm2708.dtsi bcm2709.dtsi bcm2710.dtsi
- bcm2708_common.dtsi
-
-This patch introduces this dependency:
-
- bcm2708.dtsi bcm2709.dtsi
- bcm2708-rpi.dtsi
- bcm270x.dtsi
- bcm2835.dtsi bcm2836.dtsi
- bcm283x.dtsi
-
-And:
- bcm2710.dtsi
- bcm2708-rpi.dtsi
- bcm270x.dtsi
- bcm283x.dtsi
-
-bcm270x.dtsi contains the downstream bcm283x.dtsi diff.
-bcm2708-rpi.dtsi is the downstream version of bcm2835-rpi.dtsi.
-
-Other changes:
-- The led node has moved from /soc/leds to /leds. This is not a problem
- since the label is used to reference it.
-- The clk_osc reg property changes from 6 to 3.
-- The gpu nodes has their interrupt property set in the base file.
-- the clocks label does not point to the /clocks node anymore, but
- points to the cprman node. This is not a problem since the overlays
- that use the clock node refer to it directly: target-path = "/clocks";
-- some nodes now have 2 labels since mainline and downstream differs in
- this respect: cprman/clocks, spi0/spi, gpu/vc4.
-- some nodes doesn't have an explicit status = "okay" since they're not
- disabled in the base file: watchdog and random.
-- gpiomem doesn't need an explicit status = "okay".
-- bcm2708-rpi-cm.dts got the hpd-gpios property from bcm2708_common.dtsi,
- it's now set directly in that file.
-- bcm2709-rpi-2-b.dts has the timer node moved from /soc/timer to /timer.
-- Removed clock-frequency property on the bcm{2709,2710}.dtsi timer nodes.

-
-The EPAPR standard says to use "phandle" properties to store phandles,

-generates both, but adding "-H epapr" causes it to only generate
-"phandle"s, saving some space and clutter.

-+Introduction
-+============
-+
-+This directory contains Device Tree overlays. Device Tree makes it possible
-+to support many hardware configurations with a single kernel and without the
-+need to explicitly load or blacklist kernel modules. Note that this isn't a
-+"pure" Device Tree configuration (c.f. MACH_BCM2835) - some on-board devices
-+are still configured by the board support code, but the intention is to
-+eventually reach that goal.
-+
-+On Raspberry Pi, Device Tree usage is controlled from /boot/config.txt. By
-+default, the Raspberry Pi kernel boots with device tree enabled. You can
-+completely disable DT usage (for now) by adding:
-+
-+ device_tree=
-+
-+to your config.txt, which should cause your Pi to revert to the old way of
-+doing things after a reboot.
-+
-+In /boot you will find a .dtb for each base platform. This describes the
-+hardware that is part of the Raspberry Pi board. The loader (start.elf and its
-+siblings) selects the .dtb file appropriate for the platform by name, and reads
-+it into memory. At this point, all of the optional interfaces (i2c, i2s, spi)
-+are disabled, but they can be enabled using Device Tree parameters:
-+
-+ dtparam=i2c=on,i2s=on,spi=on
-+
-+However, this shouldn't be necessary in many use cases because loading an
-+overlay that requires one of those interfaces will cause it to be enabled
-+automatically, and it is advisable to only enable interfaces if they are
-+needed.
-+
-+Configuring additional, optional hardware is done using Device Tree overlays
-+(see below).
-+
-+GPIO numbering uses the hardware pin numbering scheme (aka BCM scheme) and
-+not the physical pin numbers.
-+
-+raspi-config
-+============
-+
-+The Advanced Options section of the raspi-config utility can enable and disable
-+Device Tree use, as well as toggling the I2C and SPI interfaces. Note that it
-+is possible to both enable an interface and blacklist the driver, if for some
-+reason you should want to defer the loading.
-+
-+Modules
-+=======
-+
-+As well as describing the hardware, Device Tree also gives enough information
-+to allow suitable driver modules to be located and loaded, with the corollary
-+that unneeded modules are not loaded. As a result it should be possible to
-+remove lines from /etc/modules, and /etc/modprobe.d/raspi-blacklist.conf can
-+have its contents deleted (or commented out).
-+
-+Using Overlays
-+==============
-+
-+Overlays are loaded using the "dtoverlay" config.txt setting. As an example,
-+consider I2C Real Time Clock drivers. In the pre-DT world these would be loaded
-+by writing a magic string comprising a device identifier and an I2C address to
-+a special file in /sys/class/i2c-adapter, having first loaded the driver for
-+the I2C interface and the RTC device - something like this:
-+
-+ modprobe i2c-bcm2835
-+ modprobe rtc-ds1307
-+ echo ds1307 0x68 > /sys/class/i2c-adapter/i2c-1/new_device
-+
-+With DT enabled, this becomes a line in config.txt:
-+
-+ dtoverlay=i2c-rtc,ds1307
-+
-+This causes the file /boot/overlays/i2c-rtc.dtbo to be loaded and a "node"
-+describing the DS1307 I2C device to be added to the Device Tree for the Pi. By
-+default it usees address 0x68, but this can be modified with an additional DT
-+parameter:
-+
-+ dtoverlay=i2c-rtc,ds1307,addr=0x68
-+
-+Parameters usually have default values, although certain parameters are
-+mandatory. See the list of overlays below for a description of the parameters
-+and their defaults.
-+
-+Making new Overlays based on existing Overlays
-+==============================================
-+
-+Recent overlays have been designed in a more general way, so that they can be
-+adapted to hardware by changing their parameters. When you have additional
-+hardware with more than one device of a kind, you end up using the same overlay
-+multiple times with other parameters, e.g.
-+
-+ # 2 CAN FD interfaces on spi but with different pins
-+ dtoverlay=mcp251xfd,spi0-0,interrupt=25
-+ dtoverlay=mcp251xfd,spi0-1,interrupt=24
-+
-+ # a realtime clock on i2c
-+ dtoverlay=i2c-rtc,pcf85063
-+
-+While this approach does work, it requires knowledge about the hardware design.
-+It is more feasible to simplify things for the end user by providing a single
-+overlay as it is done the traditional way.
-+
-+A new overlay can be generated by using ovmerge utility.
-+https://github.com/raspberrypi/utils/blob/master/ovmerge/ovmerge
-+
-+To generate an overlay for the above configuration we pass the configuration
-+to ovmerge and add the -c flag.
-+
-+ ovmerge -c mcp251xfd-overlay.dts,spi0-0,interrupt=25 \
-+ mcp251xfd-overlay.dts,spi0-1,interrupt=24 \
-+ i2c-rtc-overlay.dts,pcf85063 \
-+ >> merged-overlay.dts
-+
-+The -c option writes the command above as a comment into the overlay as
-+a marker that this overlay is generated and how it was generated.
-+After compiling the overlay it can be loaded in a single line.
-+
-+ dtoverlay=merged
-+
-+It does the same as the original configuration but without parameters.
-+

-+
-+ pwr_led_trigger
-+ pwr_led_activelow
-+ pwr_led_gpio
-+ As for act_led_*, but using the PWR LED.
-+ Not available on Model A/B boards.
-+
-+ N.B. It is recommended to only enable those interfaces that are needed.
-+ Leaving all interfaces enabled can lead to unwanted behaviour (i2c_vc
-+ interfering with Pi Camera, I2S and SPI hogging GPIO pins, etc.)
-+ Note also that i2c, i2c_arm and i2c_vc are aliases for the physical
-+ interfaces i2c0 and i2c1. Use of the numeric variants is still possible
-+ but deprecated because the ARM/VC assignments differ between board
-+ revisions. The same board-specific mapping applies to i2c_baudrate,
-+ and the other i2c baudrate parameters.
-+
-+
-+Name: act-led
-+Info: Pi 3B, 3B+, 3A+ and 4B use a GPIO expander to drive the LEDs which can
-+ only be accessed from the VPU. There is a special driver for this with a
-+ separate DT node, which has the unfortunate consequence of breaking the
-+ act_led_gpio and act_led_activelow dtparams.
-+ This overlay changes the GPIO controller back to the standard one and
-+ restores the dtparams.

-+

-+
-+ The following features of fbtft_device have not been ported over:
-+ - parallel bus is not supported
-+ - the init property which overrides the controller initialization
-+ sequence is not supported as a parameter due to memory limitations in

-+Name: gpio-led
-+Info: This is a generic overlay for activating LEDs (or any other component)
-+ by a GPIO pin. Multiple LEDs can be set up using multiple calls to the
-+ overlay. While there are many existing methods to activate LEDs on the
-+ RPi, this method offers some advantages:
-+ 1) Does not require any userspace programs.
-+ 2) LEDs can be connected to the kernel's led-trigger framework,
-+ and drive the LED based on triggers such as cpu load, heartbeat,
-+ kernel panic, key input, timers and others.
-+ 3) LED can be tied to the input state of another GPIO pin.
-+ 4) The LED is setup early during the kernel boot process (useful
-+ for cpu/heartbeat/panic triggers).
-+
-+ Typical electrical connection is:
-+ RPI-GPIO.19 -> LED -> 300ohm resister -> RPI-GND
-+ The GPIO pin number can be changed with the 'gpio=' parameter.
-+
-+ To control an LED from userspace, write a 0 or 1 value:
-+ echo 1 > /sys/class/leds/myled1/brightness
-+ The 'myled1' name can be changed with the 'label=' parameter.
-+
-+ To connect the LED to a kernel trigger from userspace:
-+ echo cpu > /sys/class/leds/myled1/trigger
-+ echo heartbeat > /sys/class/leds/myled1/trigger
-+ echo none > /sys/class/leds/myled1/trigger
-+ To connect the LED to GPIO.26 pin (physical pin 37):
-+ echo gpio > /sys/class/leds/myled1/trigger
-+ echo 26 > /sys/class/leds/myled1/gpio
-+ Available triggers:
-+ cat /sys/class/leds/myled1/trigger
-+
-+ More information about the Linux kernel LED/Trigger system:
-+ https://www.kernel.org/doc/Documentation/leds/leds-class.rst
-+ https://www.kernel.org/doc/Documentation/leds/ledtrig-oneshot.rst
-+Load: dtoverlay=gpio-led,<param>=<val>
-+Params: gpio GPIO pin connected to the LED (default 19)
-+ label The label for this LED. It will appear under
-+ /sys/class/leds/<label> . Default 'myled1'.
-+ trigger Set the led-trigger to connect to this LED.
-+ default 'none' (LED is user-controlled).
-+ Some possible triggers:
-+ cpu - CPU load (all CPUs)
-+ cpu0 - CPU load of first CPU.
-+ mmc - disk activity (all disks)
-+ panic - turn on on kernel panic
-+ heartbeat - indicate system health
-+ gpio - connect to a GPIO input pin (note:
-+ currently the GPIO PIN can not be set
-+ using overlay parameters, must be
-+ done in userspace, see examples above.
-+ active_low Set to 1 to turn invert the LED control
-+ (writing 0 to /sys/class/leds/XXX/brightness
-+ will turn on the GPIO/LED). Default '0'.
-+
-+
-+Name: gpio-no-bank0-irq
-+Info: Use this overlay to disable GPIO interrupts for GPIOs in bank 0 (0-27),
-+ which can be useful for UIO drivers.
-+ N.B. Using this overlay will trigger a kernel WARN during booting, but
-+ this can safely be ignored - the system should work as expected.

-+Params: <None>
-+
-+
-+Name: gpio-poweroff
-+Info: Drives a GPIO high or low on poweroff (including halt). Using this
-+ overlay interferes with the normal power-down sequence, preventing the
-+ kernel from resetting the SoC (a necessary step in a normal power-off
-+ or reboot). This also disables the ability to trigger a boot by driving
-+ GPIO3 low.
-+
-+ The GPIO starts in an inactive state. At poweroff time it is driven
-+ active for 100ms, then inactive for 100ms, then active again. It is
-+ safe to remove the power at any point after the initial activation of
-+ the GPIO.
-+
-+ Users of this overlay are required to provide an external mechanism to
-+ switch off the power supply when signalled - failure to do so results
-+ in a kernel BUG, increased power consumption and undefined behaviour.
-+Load: dtoverlay=gpio-poweroff,<param>=<val>
-+Params: gpiopin GPIO for signalling (default 26)
-+
-+ active_low Set if the power control device requires a
-+ high->low transition to trigger a power-down.
-+ Note that this will require the support of a
-+ custom dt-blob.bin to prevent a power-down
-+ during the boot process, and that a reboot
-+ will also cause the pin to go low.
-+ input Set if the gpio pin should be configured as
-+ an input.
-+ export Set to export the configured pin to sysfs
-+ active_delay_ms Initial GPIO active period (default 100)
-+ inactive_delay_ms Subsequent GPIO inactive period (default 100)
-+ timeout_ms Specify (in ms) how long the kernel waits for
-+ power-down before issuing a WARN (default 3000).
-+
-+
-+Name: gpio-shutdown
-+Info: Initiates a shutdown when GPIO pin changes. The given GPIO pin
-+ is configured as an input key that generates KEY_POWER events.
-+
-+ This event is handled by systemd-logind by initiating a
-+ shutdown. Systemd versions older than 225 need an udev rule
-+ enable listening to the input device:
-+
-+ ACTION!="REMOVE", SUBSYSTEM=="input", KERNEL=="event*", \
-+ SUBSYSTEMS=="platform", DRIVERS=="gpio-keys", \
-+ ATTRS{keys}=="116", TAG+="power-switch"
-+
-+ Alternatively this event can be handled also on systems without
-+ systemd, just by traditional SysV init daemon. KEY_POWER event
-+ (keycode 116) needs to be mapped to KeyboardSignal on console
-+ and then kb::kbrequest inittab action which is triggered by
-+ KeyboardSignal from console can be configured to issue system
-+ shutdown. Steps for this configuration are:
-+
-+ Add following lines to the /etc/console-setup/remap.inc file:
-+
-+ # Key Power as special keypress
-+ keycode 116 = KeyboardSignal
-+
-+ Then add following lines to /etc/inittab file:
-+
-+ # Action on special keypress (Key Power)
-+ kb::kbrequest:/sbin/shutdown -t1 -a -h -P now
-+
-+ And finally reload configuration by calling following commands:
-+
-+ # dpkg-reconfigure console-setup
-+ # service console-setup reload
-+ # init q
-+
-+ This overlay only handles shutdown. After shutdown, the system
-+ can be powered up again by driving GPIO3 low. The default
-+ configuration uses GPIO3 with a pullup, so if you connect a
-+ button between GPIO3 and GND (pin 5 and 6 on the 40-pin header),
-+ you get a shutdown and power-up button. Please note that
-+ Raspberry Pi 1 Model B rev 1 uses GPIO1 instead of GPIO3.
-+Load: dtoverlay=gpio-shutdown,<param>=<val>
-+Params: gpio_pin GPIO pin to trigger on (default 3)
-+ For Raspberry Pi 1 Model B rev 1 set this
-+ explicitly to value 1, e.g.:
-+
-+ dtoverlay=gpio-shutdown,gpio_pin=1
-+
-+ active_low When this is 1 (active low), a falling
-+ edge generates a key down event and a
-+ rising edge generates a key up event.
-+ When this is 0 (active high), this is
-+ reversed. The default is 1 (active low).
-+
-+ gpio_pull Desired pull-up/down state (off, down, up)
-+ Default is "up".
-+
-+ Note that the default pin (GPIO3) has an
-+ external pullup. Same applies for GPIO1
-+ on Raspberry Pi 1 Model B rev 1.
-+
-+ debounce Specify the debounce interval in milliseconds
-+ (default 100)

-+
-+ Some notable differences with the DRM driver compared to fbtft:
-+ - The display is turned on when it's first used and not on driver load
-+ as with fbtft. So if nothing uses the display it stays off.
-+ - Can run with a higher SPI clock increasing framerate. This is possible
-+ since the driver avoids messing up the controller configuration due to
-+ transmission errors by running config commands at 10MHz and only pixel
-+ data at full speed (occasional pixel glitch might occur).
-+ - PWM backlight is supported.

-+ * - https://www.raspberrypi.org/forums/viewtopic.php?f=107&p=1367135#p1365084
-+ *
-+ * Optional parameters:
-+ * - "gpiopin" - BCM number of the pin driving the fan, default 12 (GPIO12);
-+ * - "temp" - CPU temperature at which fan is started in millicelsius, default 55000;

-+// dtparams:

-+// s17-spi<n>-<m>-present - 8-bit integer, bitmap indicating MCP23S17 devices present on SPI<n>, CS#<m>.
-+// s08-spi<n>-<m>-int-gpio - integer, enables interrupts on a single MCP23S08 device on SPI<n>, CS#<m>, specifies the GPIO pin to which INT output is connected.
-+// s17-spi<n>-<m>-int-gpio - integer, enables mirrored interrupts on a single MCP23S17 device on SPI<n>, CS#<m>, specifies the GPIO pin to which either INTA or INTB output is connected.
-+//
-+// If devices are present on SPI1 or SPI2, those interfaces must be enabled with one of the spi1-1/2/3cs and/or spi2-1/2/3cs overlays.
-+// If interrupts are enabled for a device on a given CS# on a SPI bus, that device must be the only one present on that SPI bus/CS#.
-+//
-+// Example 1: A single MCP23S17 device on SPI0, CS#0 with its SPI addr set to 0 and INTA output connected to GPIO25:
-+// dtoverlay=mcp23s17:s17-spi0-0-present=1,s17-spi0-0-int-gpio=25

-+ * PiFace Digital, Device Tree Overlay.
-+ * Copyright (C) 2020 Thomas Preston <thomas.preston@codethink.co.uk>
-+ *
-+ * The PiFace Digital is a convenient breakout board for the Microchip mcp23s17
-+ * SPI GPIO port expander.
-+ *
-+ * The first eight GPIOs 0..7 (bank A) are connected to eight output terminals
-+ * and LEDs, plus two relays on the first two outputs. These output loads are
-+ * active-high.
-+ *
-+ * The next eight GPIOs 8..15 (bank B) are connected to eight input terminals
-+ * with four on-board switches connecting them to ground. Inputs devices are
-+ * therefore expected to bridge terminals to ground, so the mcp23s17 pullups are
-+ * activated for GPIO bank B.
-+ *
-+ * On PiFace Digital, the mcp23s17 is connected to the Raspberry Pi's SPI0 CS0
-+ * bus. Each SPI bus supports up to eight addressable child devices. The PiFace
-+ * Digital only supports addresses 0-4, which can be configured by jumpers JP1
-+ * and JP2.
-+ *
-+ * You can tell the driver about these jumper configurations with the
-+ * spi-present-mask bitmask:
-+ *
-+ * | JP1 | JP2 | dtoverlay line in /boot/config.txt |
-+ * | --- | --- | ------------------------------------------ |
-+ * | 0 | 0 | dtoverlay=pifacedigital |
-+ * | 0 | 0 | dtoverlay=pifacedigital:spi-present-mask=1 |
-+ * | 0 | 1 | dtoverlay=pifacedigital:spi-present-mask=2 |
-+ * | 1 | 0 | dtoverlay=pifacedigital:spi-present-mask=4 |
-+ * | 1 | 1 | dtoverlay=pifacedigital:spi-present-mask=8 |
-+ *
-+ * # Example
-+ * Set the dtoverlay config in /boot/config.txt and power off the Raspberry Pi:
-+ *
-+ * $ grep pifacedigital /boot/config.txt
-+ * dtoverlay=pifacedigital
-+ * $ sudo systemctl poweroff
-+ *
-+ * Attach the PiFace Digital and power on the Raspberry Pi.
-+ * Then use the libgpiod tools to query the device:
-+ *
-+ * $ sudo apt install gpiod
-+ * $ gpiodetect | grep mcp23s17
-+ * gpiochip2 [mcp23s17.0] (16 lines)
-+ *
-+ * Set GPIO outputs 0, 2 and 5:
-+ *
-+ * $ gpioset gpiochip2 0=1 2=1 5=1
-+ *
-+ * Get GPIO status (input GPIO 8..15 are high, because they are active-low):
-+ *
-+ * $ gpioget gpiochip2 {8..15}
-+ * 1 1 1 1 1 1 1 1
-+ *
-+ * And even monitor interrupts:
-+ *
-+ * $ gpiomon gpiochip2 {8..15}
-+ * event: FALLING EDGE offset: 11 timestamp: [1597361662.926741667]
-+ * event: RISING EDGE offset: 11 timestamp: [1597361663.062555051]

-Subject: [PATCH] Register the clocks early during the boot process, so
- that special/critical clocks can get enabled early on in the boot process
- avoiding the risk of disabling a clock, pll_divider or pll when a claiming
- driver fails to install propperly - maybe it needs to defer.

-Subject: [PATCH] clk-bcm2835: Mark used PLLs and dividers CRITICAL
-
-The VPU configures and relies on several PLLs and dividers. Mark all
-enabled dividers and their PLLs as CRITICAL to prevent the kernel from
-switching them off.

-
-The claim-clocks property can be used to prevent PLLs and dividers
-from being marked as critical. It contains a vector of clock IDs,

-Subject: [PATCH] clk-bcm2835: Read max core clock from firmware
-
-The VPU is responsible for managing the core clock, usually under
-direction from the bcm2835-cpufreq driver but not via the clk-bcm2835
-driver. Since the core frequency can change without warning, it is
-safer to report the maximum clock rate to users of the core clock -
-I2C, SPI and the mini UART - to err on the safe side when calculating
-clock divisors.
-
-If the DT node for the clock driver includes a reference to the
-firmware node, use the firmware API to query the maximum core clock
-instead of reading the divider registers.
-
-Prior to this patch, a "100KHz" I2C bus was sometimes clocked at about
-160KHz. In particular, switching to the 4.9 kernel was likely to break
-SenseHAT usage on a Pi3.

-
-This reverts commit ffee202a78c2980688bc5d2f7d56480e69a5e0c9.
-
-The commit "Bluetooth: Always request for user confirmation for Just
-Works" prevents BLE devices pairing in (at least) the Raspberry Pi OS
-GUI. After reverting it, pairing works again. Although this companion
-commit ("... (LE SC)") has not been demonstrated to be problematic,
-it follows the same logic and therefore could affect some use cases.
-
-If another solution to the problem is found then this reversion will
-be removed.

-SQUASH: smsc95xx: Use dev_mod_addr to set MAC addr
-
-Since adeef3e32146 ("net: constify netdev->dev_addr") it has been
-illegal to write to the dev_addr MAC address field. Later commits
-have added explicit checks that it hasn't been modified by nefarious
-means. The dev_addr_mod helper function is the accepted way to change
-the dev_addr field, so use it.
-
-Squash with 96c1def63ee1 ("Allow mac address to be set in smsc95xx").

-The Raspberry Pi firmware looks at the RSTS register to know which
-partition to boot from. The reboot syscall command
-LINUX_REBOOT_CMD_RESTART2 supports passing in a string argument.
-
-Add support for passing in a partition number 0..63 to boot from.
-Partition 63 is a special partiton indicating halt.
-If the partition doesn't exist, the firmware falls back to partition 0.

-Subject: [PATCH] Update vfpmodule.c
-
-Christopher Alexander Tobias Schulze - May 2, 2015, 11:57 a.m.
-This patch fixes a problem with VFP state save and restore related
-to exception handling (panic with message "BUG: unsupported FP
-instruction in kernel mode") present on VFP11 floating point units
-(as used with ARM1176JZF-S CPUs, e.g. on first generation Raspberry
-Pi boards). This patch was developed and discussed on
-
- https://github.com/raspberrypi/linux/issues/859
-
-A precondition to see the crashes is that floating point exception
-traps are enabled. In this case, the VFP11 might determine that a FPU
-operation needs to trap at a point in time when it is not possible to
-signal this to the ARM11 core any more. The VFP11 will then set the
-FPEXC.EX bit and store the trapped opcode in FPINST. (In some cases,
-a second opcode might have been accepted by the VFP11 before the
-exception was detected and could be reported to the ARM11 - in this
-case, the VFP11 also sets FPEXC.FP2V and stores the second opcode in
-FPINST2.)
-
-If FPEXC.EX is set, the VFP11 will "bounce" the next FPU opcode issued
-by the ARM11 CPU, which will be seen by the ARM11 as an undefined opcode
-trap. The VFP support code examines the FPEXC.EX and FPEXC.FP2V bits
-to decide what actions to take, i.e., whether to emulate the opcodes
-found in FPINST and FPINST2, and whether to retry the bounced instruction.
-
-If a user space application has left the VFP11 in this "pending trap"
-state, the next FPU opcode issued to the VFP11 might actually be the
-VSTMIA operation vfp_save_state() uses to store the FPU registers
-to memory (in our test cases, when building the signal stack frame).
-In this case, the kernel crashes as described above.
-
-This patch fixes the problem by making sure that vfp_save_state() is
-always entered with FPEXC.EX cleared. (The current value of FPEXC has
-already been saved, so this does not corrupt the context. Clearing
-FPEXC.EX has no effects on FPINST or FPINST2. Also note that many
-callers already modify FPEXC by setting FPEXC.EN before invoking
-vfp_save_state().)
-
-This patch also addresses a second problem related to FPEXC.EX: After
-returning from signal handling, the kernel reloads the VFP context
-from the user mode stack. However, the current code explicitly clears
-both FPEXC.EX and FPEXC.FP2V during reload. As VFP11 requires these
-bits to be preserved, this patch disables clearing them for VFP
-implementations belonging to architecture 1. There should be no
-negative side effects: the user can set both bits by executing FPU
-opcodes anyway, and while user code may now place arbitrary values
-into FPINST and FPINST2 (e.g., non-VFP ARM opcodes) the VFP support
-code knows which instructions can be emulated, and rejects other
-opcodes with "unhandled bounce" messages, so there should be no
-security impact from allowing reloading FPEXC.EX and FPEXC.FP2V.

-Subject: [PATCH] i2c: bcm2835: Add debug support
-MIME-Version: 1.0
-Content-Type: text/plain; charset=UTF-8
-Content-Transfer-Encoding: 8bit
-
-This adds a debug module parameter to aid in debugging transfer issues
-by printing info to the kernel log. When enabled, status values are
-collected in the interrupt routine and msg info in
-bcm2835_i2c_start_transfer(). This is done in a way that tries to avoid
-affecting timing. Having printk in the isr can mask issues.
-
-debug values (additive):
-1: Print info on error
-2: Print info on all transfers
-3: Print messages before transfer is started
-
-The value can be changed at runtime:
-/sys/module/i2c_bcm2835/parameters/debug
-
-Example output, debug=3:
-[ 747.114448] bcm2835_i2c_xfer: msg(1/2) write addr=0x54, len=2 flags= [i2c1]
-[ 747.114463] bcm2835_i2c_xfer: msg(2/2) read addr=0x54, len=32 flags= [i2c1]

-Subject: [PATCH] irqchip: irq-bcm2836: Remove regmap and syscon use
-
-The syscon node defines a register range that duplicates that used by
-the local_intc node on bcm2836/7. Since irq-bcm2835 and irq-bcm2836 are
-built in and always present together (both drivers are enabled by
-CONFIG_ARCH_BCM2835), it is possible to replace the syscon usage with a
-global variable that simplifies the code. Doing so does lose the
-locking provided by regmap, but as only one side is using the regmap
-interface (irq-bcm2835 uses readl and write) there is no loss of
-atomicity.

-
-The pl011 register accessor functions use the _relaxed versions of the
-standard readl() and writel() functions, meaning that there are no
-automatic memory barriers. When polling a FIFO status register to check
-for fullness, it is necessary to ensure that any outstanding writes have
-completed; otherwise the flags are effectively stale, making it possible
-that the next write is to a full FIFO.

-
-The BCM2835 PL011 implementation seems to have a bug that can lead to a
-transmission lockup if CTS changes frequently. A workaround was added to

-Subject: [PATCH] tty: amba-pl011: Avoid rare write-when-full error
-
-Under some circumstances on BCM283x processors data loss can be
-observed - a single byte missing from the TX output stream. These bytes
-are always the last byte of a batch of 8 written from pl011_tx_chars
-when from_irq is true, meaning that the FIFO full flag is not checked
-before writing.
-
-The transmit optimisation relies on the FIFO being half-empty when the
-TX interrupt is raised. Instrumenting the driver further showed that
-the failure case correlated with the TX FIFO full flag being set at the
-point where the last byte was written to the data register, which
-explains the data loss but not how the FIFO appeared to be prematurely
-full. A possible explanation is that a FIFO write was in flight at the
-time the interrupt was raised, but as yet there is no hypothesis as to
-how this might occur.
-
-In the absence of a clear understanding of the failure mechanism, avoid
-the problem by checking the FIFO levels before writing the last byte of
-the group, which will have minimal performance impact.

-Add FIQ patch to dwc_otg driver. Enable with dwc_otg.fiq_fix_enable=1. Should give about 10% more ARM performance.
-Thanks to Gordon and Costas
-
-Avoid dynamic memory allocation for channel lock in USB driver. Thanks ddv2005.
-
-Add NAK holdoff scheme. Enabled by default, disable with dwc_otg.nak_holdoff_enable=0. Thanks gsh
-
-Make sure we wait for the reset to finish
-
-dwc_otg: fix bug in dwc_otg_hcd.c resulting in silent kernel
- memory corruption, escalating to OOPS under high USB load.
-
-dwc_otg: Fix unsafe access of QTD during URB enqueue
-
-In dwc_otg_hcd_urb_enqueue during qtd creation, it was possible that the
-transaction could complete almost immediately after the qtd was assigned
-to a host channel during URB enqueue, which meant the qtd pointer was no
-longer valid having been completed and removed. Usually, this resulted in
-an OOPS during URB submission. By predetermining whether transactions
-need to be queued or not, this unsafe pointer access is avoided.
-
-This bug was only evident on the Pi model A where a device was attached
-that had no periodic endpoints (e.g. USB pendrive or some wlan devices).
-
-dwc_otg: Fix incorrect URB allocation error handling
-
-If the memory allocation for a dwc_otg_urb failed, the kernel would OOPS
-because for some reason a member of the *unallocated* struct was set to
-zero. Error handling changed to fail correctly.
-
-dwc_otg: fix potential use-after-free case in interrupt handler
-
-If a transaction had previously aborted, certain interrupts are
-enabled to track error counts and reset where necessary. On IN
-endpoints the host generates an ACK interrupt near-simultaneously
-with completion of transfer. In the case where this transfer had
-previously had an error, this results in a use-after-free on
-the QTD memory space with a 1-byte length being overwritten to
-0x00.
-
-dwc_otg: add handling of SPLIT transaction data toggle errors
-
-Previously a data toggle error on packets from a USB1.1 device behind
-a TT would result in the Pi locking up as the driver never handled
-the associated interrupt. Patch adds basic retry mechanism and
-interrupt acknowledgement to cater for either a chance toggle error or
-for devices that have a broken initial toggle state (FT8U232/FT232BM).
-
-dwc_otg: implement tasklet for returning URBs to usbcore hcd layer
-
-The dwc_otg driver interrupt handler for transfer completion will spend
-a very long time with interrupts disabled when a URB is completed -
-this is because usb_hcd_giveback_urb is called from within the handler
-which for a USB device driver with complicated processing (e.g. webcam)
-will take an exorbitant amount of time to complete. This results in
-missed completion interrupts for other USB packets which lead to them
-being dropped due to microframe overruns.
-
-This patch splits returning the URB to the usb hcd layer into a
-high-priority tasklet. This will have most benefit for isochronous IN
-transfers but will also have incidental benefit where multiple periodic

-dwc_otg: fix NAK holdoff and allow on split transactions only
-
-This corrects a bug where if a single active non-periodic endpoint
-had at least one transaction in its qh, on frnum == MAX_FRNUM the qh
-would get skipped and never get queued again. This would result in
-a silent device until error detection (automatic or otherwise) would
-either reset the device or flush and requeue the URBs.
-
-Additionally the NAK holdoff was enabled for all transactions - this
-would potentially stall a HS endpoint for 1ms if a previous error state
-enabled this interrupt and the next response was a NAK. Fix so that
-only split transactions get held off.
-
-dwc_otg: Call usb_hcd_unlink_urb_from_ep with lock held in completion handler
-
-usb_hcd_unlink_urb_from_ep must be called with the HCD lock held. Calling it
-asynchronously in the tasklet was not safe (regression in
-c4564d4a1a0a9b10d4419e48239f5d99e88d2667).
-
-This change unlinks it from the endpoint prior to queueing it for handling in
-the tasklet, and also adds a check to ensure the urb is OK to be unlinked
-before doing so.
-
-NULL pointer dereference kernel oopses had been observed in usb_hcd_giveback_urb
-when a USB device was unplugged/replugged during data transfer. This effect
-was reproduced using automated USB port power control, hundreds of replug
-events were performed during active transfers to confirm that the problem was
-eliminated.

-dwc_otg: mask correct interrupts after transaction error recovery
-
-The dwc_otg driver will unmask certain interrupts on a transaction
-that previously halted in the error state in order to reset the
-QTD error count. The various fine-grained interrupt handlers do not
-consider that other interrupts besides themselves were unmasked.
-
-By disabling the two other interrupts only ever enabled in DMA mode
-for this purpose, we can avoid unnecessary function calls in the
-IRQ handler. This will also prevent an unneccesary FIQ interrupt
-from being generated if the FIQ is enabled.
-
-dwc_otg: fiq: prevent FIQ thrash and incorrect state passing to IRQ
-
-In the case of a transaction to a device that had previously aborted
-due to an error, several interrupts are enabled to reset the error
-count when a device responds. This has the side-effect of making the
-FIQ thrash because the hardware will generate multiple instances of
-a NAK on an IN bulk/interrupt endpoint and multiple instances of ACK
-on an OUT bulk/interrupt endpoint. Make the FIQ mask and clear the
-associated interrupts.
-
-Additionally, on non-split transactions make sure that only unmasked
-interrupts are cleared. This caused a hard-to-trigger but serious
-race condition when you had the combination of an endpoint awaiting
-error recovery and a transaction completed on an endpoint - due to
-the sequencing and timing of interrupts generated by the dwc_otg core,
-it was possible to confuse the IRQ handler.
-
-Fix function tracing
-
-dwc_otg: whitespace cleanup in dwc_otg_urb_enqueue
-
-dwc_otg: prevent OOPSes during device disconnects
-
-The dwc_otg_urb_enqueue function is thread-unsafe. In particular the
-access of urb->hcpriv, usb_hcd_link_urb_to_ep, dwc_otg_urb->qtd and
-friends does not occur within a critical section and so if a device
-was unplugged during activity there was a high chance that the
-usbcore hub_thread would try to disable the endpoint with partially-
-formed entries in the URB queue. This would result in BUG() or null
-pointer dereferences.
-
-Fix so that access of urb->hcpriv, enqueuing to the hardware and
-adding to usbcore endpoint URB lists is contained within a single
-critical section.
-
-dwc_otg: prevent BUG() in TT allocation if hub address is > 16
-
-A fixed-size array is used to track TT allocation. This was
-previously set to 16 which caused a crash because
-dwc_otg_hcd_allocate_port would read past the end of the array.
-
-This was hit if a hub was plugged in which enumerated as addr > 16,
-due to previous device resets or unplugs.
-
-Also add #ifdef FIQ_DEBUG around hcd->hub_port_alloc[], which grows
-to a large size if 128 hub addresses are supported. This field is
-for debug only for tracking which frame an allocate happened in.
-
-dwc_otg: make channel halts with unknown state less damaging
-
-If the IRQ received a channel halt interrupt through the FIQ
-with no other bits set, the IRQ would not release the host
-channel and never complete the URB.
-
-Add catchall handling to treat as a transaction error and retry.
-
-dwc_otg: fiq_split: use TTs with more granularity
-
-This fixes certain issues with split transaction scheduling.
-
-- Isochronous multi-packet OUT transactions now hog the TT until
- they are completed - this prevents hubs aborting transactions
- if they get a periodic start-split out-of-order
-- Don't perform TT allocation on non-periodic endpoints - this
- allows simultaneous use of the TT's bulk/control and periodic
- transaction buffers
-
-This commit will mainly affect USB audio playback.
-
-dwc_otg: fix potential sleep while atomic during urb enqueue
-
-Fixes a regression introduced with eb1b482a. Kmalloc called from
-dwc_otg_hcd_qtd_add / dwc_otg_hcd_qtd_create did not always have
-the GPF_ATOMIC flag set. Force this flag when inside the larger
-critical section.

-
-dwc_otg: prevent crashes on host port disconnects
-
-Fix several issues resulting in crashes or inconsistent state
-if a Model A root port was disconnected.
-
-- Clean up queue heads properly in kill_urbs_in_qh_list by
- removing the empty QHs from the schedule lists
-- Set the halt status properly to prevent IRQ handlers from
- using freed memory
-- Add fiq_split related cleanup for saved registers
-- Make microframe scheduling reclaim host channels if
- active during a disconnect
-- Abort URBs with -ESHUTDOWN status response, informing
- device drivers so they respond in a more correct fashion
- and don't try to resubmit URBs
-- Prevent IRQ handlers from attempting to handle channel
- interrupts if the associated URB was dequeued (and the
- driver state was cleared)
-
-dwc_otg: prevent leaking URBs during enqueue
-
-A dwc_otg_urb would get leaked if the HCD enqueue function
-failed for any reason. Free the URB at the appropriate points.
-
-dwc_otg: Enable NAK holdoff for control split transactions
-
-Certain low-speed devices take a very long time to complete a
-data or status stage of a control transaction, producing NAK
-responses until they complete internal processing - the USB2.0
-spec limit is up to 500mS. This causes the same type of interrupt
-storm as seen with USB-serial dongles prior to c8edb238.
-
-In certain circumstances, usually while booting, this interrupt
-storm could cause SD card timeouts.
-
-dwc_otg: Fix for occasional lockup on boot when doing a USB reset
-
-dwc_otg: Don't issue traffic to LS devices in FS mode

-

-

-
-dwc_otg: fiq_fsm: Base commit for driver rewrite
-
-This commit removes the previous FIQ fixes entirely and adds fiq_fsm.
-
-This rewrite features much more complete support for split transactions
-and takes into account several OTG hardware bugs. High-speed
-isochronous transactions are also capable of being performed by fiq_fsm.
-
-All driver options have been removed and replaced with:
- - dwc_otg.fiq_enable (bool)
- - dwc_otg.fiq_fsm_enable (bool)
- - dwc_otg.fiq_fsm_mask (bitmask)
- - dwc_otg.nak_holdoff (unsigned int)
-
-Defaults are specified such that fiq_fsm behaves similarly to the
-previously implemented FIQ fixes.
-
-fiq_fsm: Push error recovery into the FIQ when fiq_fsm is used
-
-If the transfer associated with a QTD failed due to a bus error, the HCD
-would retry the transfer up to 3 times (implementing the USB2.0
-three-strikes retry in software).
-
-Due to the masking mechanism used by fiq_fsm, it is only possible to pass
-a single interrupt through to the HCD per-transfer.
-
-In this instance host channels would fall off the radar because the error
-reset would function, but the subsequent channel halt would be lost.
-
-Push the error count reset into the FIQ handler.
-
-fiq_fsm: Implement timeout mechanism
-
-For full-speed endpoints with a large packet size, interrupt latency
-runs the risk of the FIQ starting a transaction too late in a full-speed
-frame. If the device is still transmitting data when EOF2 for the
-downstream frame occurs, the hub will disable the port. This change is
-not reflected in the hub status endpoint and the device becomes
-unresponsive.
-
-Prevent high-bandwidth transactions from being started too late in a
-frame. The mechanism is not guaranteed: a combination of bit stuffing
-and hub latency may still result in a device overrunning.
-
-fiq_fsm: fix bounce buffer utilisation for Isochronous OUT
-
-Multi-packet isochronous OUT transactions were subject to a few bounday
-bugs. Fix them.
-
-Audio playback is now much more robust: however, an issue stands with
-devices that have adaptive sinks - ALSA plays samples too fast.
-
-dwc_otg: Return full-speed frame numbers in HS mode
-
-The frame counter increments on every *microframe* in high-speed mode.
-Most device drivers expect this number to be in full-speed frames - this
-caused considerable confusion to e.g. snd_usb_audio which uses the
-frame counter to estimate the number of samples played.
-
-fiq_fsm: save PID on completion of interrupt OUT transfers
-
-Also add edge case handling for interrupt transports.
-
-Note that for periodic split IN, data toggles are unimplemented in the
-OTG host hardware - it unconditionally accepts any PID.
-
-fiq_fsm: add missing case for fiq_fsm_tt_in_use()
-
-Certain combinations of bitrate and endpoint activity could
-result in a periodic transaction erroneously getting started
-while the previous Isochronous OUT was still active.
-
-fiq_fsm: clear hcintmsk for aborted transactions
-
-Prevents the FIQ from erroneously handling interrupts
-on a timed out channel.
-
-fiq_fsm: enable by default
-
-fiq_fsm: fix dequeues for non-periodic split transactions
-
-If a dequeue happened between the SSPLIT and CSPLIT phases of the
-transaction, the HCD would never receive an interrupt.
-
-fiq_fsm: Disable by default
-

-

-the counter wraps. Handle the resulting interrupt in this case.

-

-
-Process the host port interrupts correctly (and don't trample them).
-Root port hotplug now functional again.
-
-Fix a few thinkos with the transaction error passthrough for fiq_fsm.
-
-fiq_fsm: Implement hack for Split Interrupt transactions
-
-Hubs aren't too picky about which endpoint we send Control type split
-transactions to. By treating Interrupt transfers as Control, it is
-possible to use the non-periodic queue in the OTG core as well as the
-non-periodic FIFOs in the hub itself. This massively reduces the
-microframe exclusivity/contention that periodic split transactions
-otherwise have to enforce.
-
-It goes without saying that this is a fairly egregious USB specification
-violation, but it works.
-
-Original idea by Hans Petter Selasky @ FreeBSD.org.
-
-dwc_otg: FIQ support on SMP. Set up FIQ stack and handler on Core 0 only.
-
-dwc_otg: introduce fiq_fsm_spin(un|)lock()
-
-SMP safety for the FIQ relies on register read-modify write cycles being
-completed in the correct order. Several places in the DWC code modify
-registers also touched by the FIQ. Protect these by a bare-bones lock
-mechanism.
-
-This also makes it possible to run the FIQ and IRQ handlers on different
-cores.

-Be more careful about read-modify-write on registers that the FIQ
-also touches.
-
-Guard fiq_fsm_spin_lock with fiq_enable check
-
-fiq_fsm: Falling out of the state machine isn't fatal
-
-This edge case can be hit if the port is disabled while the FIQ is
-in the middle of a transaction. Make the effects less severe.

-
-Limit the use of __bus_to_virt() to cases where transfer_buffer_length
-is set and transfer_buffer is not set. This is done to increase the

-
-transfer_buffer should not be NULL if the length is set, but the

-might happen. drivers/usb/isp1760/isp1760-hcd.c also has a similar
-comment pointing to a possible: 'usb storage / SCSI bug'.

-If URBs reading from non-periodic split endpoints were dequeued and

-
-dwc_otg: fix several potential crash sources
-
-On root port disconnect events, the host driver state is cleared and

- spinlock
-- Move qtd dereference in dwc_otg_handle_hc_fsm() after the early-out

-- Turn catch-all BUG()s in dwc_otg_handle_hc_fsm() into warnings.

-The FIQ driver used a kzalloc'ed buffer for dummy_send,
-passing a kernel virtual address to the hardware block.
-The buffer is only ever used for a dummy read, so it
-should be harmless, but there is the chance that it will
-cause exceptions.
-
-Use a dma allocation so that we have a genuine bus address,
-and read from that.
-Free the allocation when done for good measure.

-dwc_otg: only do_split when we actually need to do a split
-
-The previous test would fail if the root port was in fullspeed mode
-and there was a hub between the FS device and the root port. While
-the transfer worked, the schedule mangling performed for high-speed
-split transfers would break leading to an 8ms polling interval.
-
-dwc_otg: fix locking around dequeueing and killing URBs
-
-kill_urbs_in_qh_list() is practically only ever called with the fiq lock
-already held, so don't spinlock twice in the case where we need to cancel
-an isochronous transfer.
-
-Also fix up a case where the global interrupt register could be read with
-the fiq lock not held.
-
-Fixes the deadlock seen in https://github.com/raspberrypi/linux/issues/2907

-ARM64/DWC_OTG: Port dwc_otg driver to ARM64
-
-In ARM64, the FIQ mechanism used by this driver is not current
-implemented. As a workaround, reqular IRQ is used instead
-of FIQ.
-
-In a separate change, the IRQ-CPU mapping is round robined
-on ARM64 to increase concurrency and allow multiple interrupts
-to be serviced at a time. This reduces the need for FIQ.
-
-Tests Run:
-
-This mechanism is most likely to break when multiple USB devices
-are attached at the same time. So the system was tested under
-stress.
-
-Devices:
-
-1. USB Speakers playing back a FLAC audio through VLC
- at 96KHz.(Higher then typically, but supported on my speakers).
-
-2. sftp transferring large files through the buildin ethernet
- connection which is connected through USB.
-
-3. Keyboard and mouse attached and being used.
-
-Although I do occasionally hear some glitches, the music seems to
-play quite well.

-dwc_otg: use align_buf for small IN control transfers (#3150)
-
-The hardware will do a 4-byte write to memory on any IN packet received
-that is between 1 and 3 bytes long. This tramples memory in the uvcvideo
-driver, as it uses a sequence of 1- and 2-byte control transfers to
-query the min/max/range/step of each individual camera control and
-gives us buffers that are offsets into a struct.
-
-Catch small control transfers in the data phase and use the align_buf
-to bounce the correct number of bytes into the URB's buffer.
-
-In general, short packets on non-control endpoints should be OK as URBs
-should have enough buffer space for a wMaxPacket size transfer.

-dwc_otg: checking the urb->transfer_buffer too early (#3332)
-
-After enable the HIGHMEM and VMSPLIT_3G, the dwc_otg driver doesn't
-work well on Pi2/3 boards with 1G physical ram. Users experience
-the failure when copying a file of 600M size to the USB stick. And
-at the same time, the dmesg shows:
-usb 1-1.1.2: reset high-speed USB device number 8 using dwc_otg
-sd 0:0:0:0: [sda] tag#0 FAILED Result: hostbyte=DID_ERROR driverbyte=DRIVER_OK
-blk_update_request: I/O error, dev sda, sector 3024048 op 0x1:(WRITE) flags 0x4000 phys_seg 15 prio class 0
-
-When this happens, the sg_buf sent to the driver is located in the
-highmem region, the usb_sg_init() in the core/message.c will leave
-transfer_buffer to NULL if the sg_buf is in highmem, but in the
-dwc_otg driver, it returns -EINVAL unconditionally if transfer_buffer
-is NULL.
-
-The driver can handle the situation of buffer to be NULL, if it is in
-DMA mode, it will convert an address from transfer_dma.
-
-But if the conversion fails or it is in the PIO mode, we should check
-buffer and return -EINVAL if it is NULL.

-dwc_otg: constrain endpoint max packet and transfer size on split IN
-
-The hcd would unconditionally set the transfer length to the endpoint
-packet size for non-isoc IN transfers. If the remaining buffer length
-was less than the length of returned data, random memory would get
-scribbled over, with bad effects if it crossed a page boundary.
-
-Force a babble error if this happens by limiting the max transfer size
-to the available buffer space. DMA will stop writing to memory on a
-babble condition.
-
-The hardware expects xfersize to be an integer multiple of maxpacket
-size, so override hcchar.b.mps as well.

-dwc_otg: fiq_fsm: add a barrier on entry into FIQ handler(s)
-
-On BCM2835, there is no hardware guarantee that multiple outstanding
-reads to different peripherals will complete in-order. The FIQ code
-uses peripheral reads without barriers for performance, so in the case
-where a read to a slow peripheral was issued immediately prior to FIQ
-entry, the first peripheral read that the FIQ did could end up with
-wrong read data returned.
-
-Add dsb(sy) on entry so that all outstanding reads are retired.
-
-The FIQ only issues reads to the dwc_otg core, so per-read barriers
-in the handler itself are not required.
-
-On BCM2836 and BCM2837 the barrier is not strictly required due to
-differences in how the peripheral bus is implemented, but having
-arch-specific handlers that introduce different latencies is risky.

-+ * The File-backed Storage Gadget acts as a USB Mass Storage device,
-+ * appearing to the host as a disk drive or as a CD-ROM drive. In addition
-+ * to providing an example of a genuinely useful gadget driver for a USB
-+ * device, it also illustrates a technique of double-buffering for increased
-+ * throughput. Last but not least, it gives an easy way to probe the
-+ * behavior of the Mass Storage drivers in a USB host.
-+ *
-+ * Backing storage is provided by a regular file or a block device, specified
-+ * by the "file" module parameter. Access can be limited to read-only by
-+ * setting the optional "ro" module parameter. (For CD-ROM emulation,
-+ * access is always read-only.) The gadget will indicate that it has
-+ * removable media if the optional "removable" module parameter is set.
-+ *
-+ * The gadget supports the Control-Bulk (CB), Control-Bulk-Interrupt (CBI),
-+ * and Bulk-Only (also known as Bulk-Bulk-Bulk or BBB) transports, selected
-+ * by the optional "transport" module parameter. It also supports the
-+ * following protocols: RBC (0x01), ATAPI or SFF-8020i (0x02), QIC-157 (0c03),
-+ * UFI (0x04), SFF-8070i (0x05), and transparent SCSI (0x06), selected by
-+ * the optional "protocol" module parameter. In addition, the default
-+ * Vendor ID, Product ID, release number and serial number can be overridden.
-+ *
-+ * There is support for multiple logical units (LUNs), each of which has
-+ * its own backing file. The number of LUNs can be set using the optional
-+ * "luns" module parameter (anywhere from 1 to 8), and the corresponding
-+ * files are specified using comma-separated lists for "file" and "ro".
-+ * The default number of LUNs is taken from the number of "file" elements;
-+ * it is 1 if "file" is not given. If "removable" is not set then a backing
-+ * file must be specified for each LUN. If it is set, then an unspecified
-+ * or empty backing filename means the LUN's medium is not loaded. Ideally
-+ * each LUN would be settable independently as a disk drive or a CD-ROM
-+ * drive, but currently all LUNs have to be the same type. The CD-ROM
-+ * emulation includes a single data track and no audio tracks; hence there
-+ * need be only one backing file per LUN.
-+ *
-+ * Requirements are modest; only a bulk-in and a bulk-out endpoint are
-+ * needed (an interrupt-out endpoint is also needed for CBI). The memory
-+ * requirement amounts to two 16K buffers, size configurable by a parameter.
-+ * Support is included for both full-speed and high-speed operation.
-+ *
-+ * Note that the driver is slightly non-portable in that it assumes a
-+ * single memory/DMA buffer will be useable for bulk-in, bulk-out, and
-+ * interrupt-in endpoints. With most device controllers this isn't an
-+ * issue, but there may be some with hardware restrictions that prevent
-+ * a buffer from being used by more than one endpoint.
-+ *
-+ * Module options:
-+ *
-+ * file=filename[,filename...]
-+ * Required if "removable" is not set, names of
-+ * the files or block devices used for
-+ * backing storage
-+ * serial=HHHH... Required serial number (string of hex chars)
-+ * ro=b[,b...] Default false, booleans for read-only access
-+ * removable Default false, boolean for removable media
-+ * luns=N Default N = number of filenames, number of
-+ * LUNs to support
-+ * nofua=b[,b...] Default false, booleans for ignore FUA flag
-+ * in SCSI WRITE(10,12) commands
-+ * stall Default determined according to the type of
-+ * USB device controller (usually true),
-+ * boolean to permit the driver to halt
-+ * bulk endpoints
-+ * cdrom Default false, boolean for whether to emulate
-+ * a CD-ROM drive
-+ * transport=XXX Default BBB, transport name (CB, CBI, or BBB)
-+ * protocol=YYY Default SCSI, protocol name (RBC, 8020 or
-+ * ATAPI, QIC, UFI, 8070, or SCSI;
-+ * also 1 - 6)
-+ * vendor=0xVVVV Default 0x0525 (NetChip), USB Vendor ID
-+ * product=0xPPPP Default 0xa4a5 (FSG), USB Product ID
-+ * release=0xRRRR Override the USB release number (bcdDevice)
-+ * buflen=N Default N=16384, buffer size used (will be
-+ * rounded down to a multiple of
-+ * PAGE_CACHE_SIZE)
-+ *
-+ * If CONFIG_USB_FILE_STORAGE_TEST is not set, only the "file", "serial", "ro",
-+ * "removable", "luns", "nofua", "stall", and "cdrom" options are available;
-+ * default values are used for everything else.
-+ *
-+ * The pathnames of the backing files and the ro settings are available in
-+ * the attribute files "file", "nofua", and "ro" in the lun<n> subdirectory of
-+ * the gadget's sysfs directory. If the "removable" option is set, writing to
-+ * these files will simulate ejecting/loading the medium (writing an empty
-+ * line means eject) and adjusting a write-enable tab. Changes to the ro
-+ * setting are not allowed when the medium is loaded or if CD-ROM emulation
-+ * is being used.
-+ *
-+ * This gadget driver is heavily based on "Gadget Zero" by David Brownell.
-+ * The driver's SCSI command interface was based on the "Information
-+ * technology - Small Computer System Interface - 2" document from
-+ * X3T9.2 Project 375D, Revision 10L, 7-SEP-93, available at
-+ * <http://www.t10.org/ftp/t10/drafts/s2/s2-r10l.pdf>. The single exception
-+ * is opcode 0x23 (READ FORMAT CAPACITIES), which was based on the
-+ * "Universal Serial Bus Mass Storage Class UFI Command Specification"
-+ * document, Revision 1.0, December 14, 1998, available at
-+ * <http://www.usb.org/developers/devclass_docs/usbmass-ufi10.pdf>.
-+ */
-+
-+
-+/*
-+ * Driver Design
-+ *
-+ * The FSG driver is fairly straightforward. There is a main kernel
-+ * thread that handles most of the work. Interrupt routines field
-+ * callbacks from the controller driver: bulk- and interrupt-request
-+ * completion notifications, endpoint-0 events, and disconnect events.
-+ * Completion events are passed to the main thread by wakeup calls. Many
-+ * ep0 requests are handled at interrupt time, but SetInterface,
-+ * SetConfiguration, and device reset requests are forwarded to the
-+ * thread in the form of "exceptions" using SIGUSR1 signals (since they
-+ * should interrupt any ongoing file I/O operations).
-+ *
-+ * The thread's main routine implements the standard command/data/status
-+ * parts of a SCSI interaction. It and its subroutines are full of tests
-+ * for pending signals/exceptions -- all this polling is necessary since
-+ * the kernel has no setjmp/longjmp equivalents. (Maybe this is an
-+ * indication that the driver really wants to be running in userspace.)
-+ * An important point is that so long as the thread is alive it keeps an
-+ * open reference to the backing file. This will prevent unmounting
-+ * the backing file's underlying filesystem and could cause problems
-+ * during system shutdown, for example. To prevent such problems, the
-+ * thread catches INT, TERM, and KILL signals and converts them into
-+ * an EXIT exception.
-+ *
-+ * In normal operation the main thread is started during the gadget's
-+ * fsg_bind() callback and stopped during fsg_unbind(). But it can also
-+ * exit when it receives a signal, and there's no point leaving the
-+ * gadget running when the thread is dead. So just before the thread
-+ * exits, it deregisters the gadget driver. This makes things a little
-+ * tricky: The driver is deregistered at two places, and the exiting
-+ * thread can indirectly call fsg_unbind() which in turn can tell the
-+ * thread to exit. The first problem is resolved through the use of the
-+ * REGISTERED atomic bitflag; the driver will only be deregistered once.
-+ * The second problem is resolved by having fsg_unbind() check
-+ * fsg->state; it won't try to stop the thread if the state is already
-+ * FSG_STATE_TERMINATED.
-+ *
-+ * To provide maximum throughput, the driver uses a circular pipeline of
-+ * buffer heads (struct fsg_buffhd). In principle the pipeline can be
-+ * arbitrarily long; in practice the benefits don't justify having more
-+ * than 2 stages (i.e., double buffering). But it helps to think of the
-+ * pipeline as being a long one. Each buffer head contains a bulk-in and
-+ * a bulk-out request pointer (since the buffer can be used for both
-+ * output and input -- directions always are given from the host's
-+ * point of view) as well as a pointer to the buffer and various state
-+ * variables.
-+ *
-+ * Use of the pipeline follows a simple protocol. There is a variable
-+ * (fsg->next_buffhd_to_fill) that points to the next buffer head to use.
-+ * At any time that buffer head may still be in use from an earlier
-+ * request, so each buffer head has a state variable indicating whether
-+ * it is EMPTY, FULL, or BUSY. Typical use involves waiting for the
-+ * buffer head to be EMPTY, filling the buffer either by file I/O or by
-+ * USB I/O (during which the buffer head is BUSY), and marking the buffer
-+ * head FULL when the I/O is complete. Then the buffer will be emptied
-+ * (again possibly by USB I/O, during which it is marked BUSY) and
-+ * finally marked EMPTY again (possibly by a completion routine).
-+ *
-+ * A module parameter tells the driver to avoid stalling the bulk
-+ * endpoints wherever the transport specification allows. This is
-+ * necessary for some UDCs like the SuperH, which cannot reliably clear a
-+ * halt on a bulk endpoint. However, under certain circumstances the
-+ * Bulk-only specification requires a stall. In such cases the driver
-+ * will halt the endpoint and set a flag indicating that it should clear
-+ * the halt in software during the next device reset. Hopefully this
-+ * will permit everything to work correctly. Furthermore, although the
-+ * specification allows the bulk-out endpoint to halt when the host sends
-+ * too much data, implementing this would cause an unavoidable race.
-+ * The driver will always use the "no-stall" approach for OUT transfers.
-+ *
-+ * One subtle point concerns sending status-stage responses for ep0
-+ * requests. Some of these requests, such as device reset, can involve
-+ * interrupting an ongoing file I/O operation, which might take an
-+ * arbitrarily long time. During that delay the host might give up on
-+ * the original ep0 request and issue a new one. When that happens the
-+ * driver should not notify the host about completion of the original
-+ * request, as the host will no longer be waiting for it. So the driver
-+ * assigns to each ep0 request a unique tag, and it keeps track of the
-+ * tag value of the request associated with a long-running exception
-+ * (device-reset, interface-change, or configuration-change). When the
-+ * exception handler is finished, the status-stage response is submitted
-+ * only if the current ep0 request tag is equal to the exception request
-+ * tag. Thus only the most recently received ep0 request will get a
-+ * status-stage response.
-+ *
-+ * Warning: This driver source file is too long. It ought to be split up
-+ * into a header file plus about 3 separate .c files, to handle the details
-+ * of the Gadget, USB Mass Storage, and SCSI protocols.

-+
-+dwc_read_reg32() and friends now take an additional parameter, a pointer to an
-+IO context struct. The IO context struct should live in an os-dependent struct
-+in your driver. As an example, the dwc_usb3 driver has an os-dependent struct
-+named 'os_dep' embedded in the main device struct. So there these calls look
-+like this:
-+
-+ dwc_read_reg32(&usb3_dev->os_dep.ioctx, &pcd->dev_global_regs->dcfg);
-+
-+ dwc_write_reg32(&usb3_dev->os_dep.ioctx,
-+ &pcd->dev_global_regs->dcfg, 0);
-+
-+Note that for the existing Linux driver ports, it is not necessary to actually
-+define the 'ioctx' member in the os-dependent struct. Since Linux does not
-+require an IO context, its macros for dwc_read_reg32() and friends do not
-+use the context pointer, so it is optimized away by the compiler. But it is
-+necessary to add the pointer parameter to all of the call sites, to be ready
-+for any future ports (such as FreeBSD) which do require an IO context.
-+
-+
-+Similarly, dwc_alloc(), dwc_alloc_atomic(), dwc_strdup(), and dwc_free() now
-+take an additional parameter, a pointer to a memory context. Examples:
-+
-+ addr = dwc_alloc(&usb3_dev->os_dep.memctx, size);
-+
-+ dwc_free(&usb3_dev->os_dep.memctx, addr);
-+
-+Again, for the Linux ports, it is not necessary to actually define the memctx
-+member, but it is necessary to add the pointer parameter to all of the call
-+sites.
-+
-+
-+Same for dwc_dma_alloc() and dwc_dma_free(). Examples:
-+
-+ virt_addr = dwc_dma_alloc(&usb3_dev->os_dep.dmactx, size, &phys_addr);
-+
-+ dwc_dma_free(&usb3_dev->os_dep.dmactx, size, virt_addr, phys_addr);
-+
-+
-+Same for dwc_mutex_alloc() and dwc_mutex_free(). Examples:
-+
-+ mutex = dwc_mutex_alloc(&usb3_dev->os_dep.mtxctx);
-+
-+ dwc_mutex_free(&usb3_dev->os_dep.mtxctx, mutex);
-+
-+
-+Same for dwc_spinlock_alloc() and dwc_spinlock_free(). Examples:
-+
-+ lock = dwc_spinlock_alloc(&usb3_dev->osdep.splctx);
-+
-+ dwc_spinlock_free(&usb3_dev->osdep.splctx, lock);
-+
-+
-+Same for dwc_timer_alloc(). Example:
-+
-+ timer = dwc_timer_alloc(&usb3_dev->os_dep.tmrctx, "dwc_usb3_tmr1",
-+ cb_func, cb_data);
-+
-+
-+Same for dwc_waitq_alloc(). Example:
-+
-+ waitq = dwc_waitq_alloc(&usb3_dev->os_dep.wtqctx);
-+
-+
-+Same for dwc_thread_run(). Example:
-+
-+ thread = dwc_thread_run(&usb3_dev->os_dep.thdctx, func,
-+ "dwc_usb3_thd1", data);
-+
-+
-+Same for dwc_workq_alloc(). Example:
-+
-+ workq = dwc_workq_alloc(&usb3_dev->osdep.wkqctx, "dwc_usb3_wkq1");
-+
-+
-+Same for dwc_task_alloc(). Example:
-+
-+ task = dwc_task_alloc(&usb3_dev->os_dep.tskctx, "dwc_usb3_tsk1",
-+ cb_func, cb_data);
-+
-+
-+In addition to the context pointer additions, a few core functions have had
-+other changes made to their parameters:
-+
-+The 'flags' parameter to dwc_spinlock_irqsave() and dwc_spinunlock_irqrestore()
-+has been changed from a uint64_t to a dwc_irqflags_t.
-+
-+dwc_thread_should_stop() now takes a 'dwc_thread_t *' parameter, because the
-+FreeBSD equivalent of that function requires it.
-+
-+And, in addition to the context pointer, dwc_task_alloc() also adds a
-+'char *name' parameter, to be consistent with dwc_thread_run() and
-+dwc_workq_alloc(), and because the FreeBSD equivalent of that function
-+requires a unique name.
-+
-+
-+Here is a complete list of the core functions that now take a pointer to a
-+context as their first parameter:
-+
-+ dwc_read_reg32
-+ dwc_read_reg64
-+ dwc_write_reg32
-+ dwc_write_reg64
-+ dwc_modify_reg32
-+ dwc_modify_reg64
-+ dwc_alloc
-+ dwc_alloc_atomic
-+ dwc_strdup
-+ dwc_free
-+ dwc_dma_alloc
-+ dwc_dma_free
-+ dwc_mutex_alloc
-+ dwc_mutex_free
-+ dwc_spinlock_alloc
-+ dwc_spinlock_free
-+ dwc_timer_alloc
-+ dwc_waitq_alloc
-+ dwc_thread_run
-+ dwc_workq_alloc
-+ dwc_task_alloc Also adds a 'char *name' as its 2nd parameter
-+
-+And here are the core functions that have other changes to their parameters:
-+
-+ dwc_spinlock_irqsave 'flags' param is now a 'dwc_irqflags_t *'
-+ dwc_spinunlock_irqrestore 'flags' param is now a 'dwc_irqflags_t'
-+ dwc_thread_should_stop Adds a 'dwc_thread_t *' parameter
-+
-+
-+
-+The changes to the core functions also require some of the other library
-+functions to change:
-+
-+ dwc_cc_if_alloc() and dwc_cc_if_free() now take a 'void *memctx'
-+ (for memory allocation) as the 1st param and a 'void *mtxctx'
-+ (for mutex allocation) as the 2nd param.
-+
-+ dwc_cc_clear(), dwc_cc_add(), dwc_cc_change(), dwc_cc_remove(),
-+ dwc_cc_data_for_save(), and dwc_cc_restore_from_data() now take a
-+ 'void *memctx' as the 1st param.
-+
-+ dwc_dh_modpow(), dwc_dh_pk(), and dwc_dh_derive_keys() now take a
-+ 'void *memctx' as the 1st param.
-+
-+ dwc_modpow() now takes a 'void *memctx' as the 1st param.
-+
-+ dwc_alloc_notification_manager() now takes a 'void *memctx' as the
-+ 1st param and a 'void *wkqctx' (for work queue allocation) as the 2nd
-+ param, and also now returns an integer value that is non-zero if
-+ allocation of its data structures or work queue fails.
-+
-+ dwc_register_notifier() now takes a 'void *memctx' as the 1st param.
-+
-+ dwc_memory_debug_start() now takes a 'void *mem_ctx' as the first
-+ param, and also now returns an integer value that is non-zero if
-+ allocation of its data structures fails.
-+
-+
-+
-+Other miscellaneous changes:
-+
-+The DEBUG_MEMORY and DEBUG_REGS #define's have been renamed to
-+DWC_DEBUG_MEMORY and DWC_DEBUG_REGS.
-+
-+The following #define's have been added to allow selectively compiling library
-+features:
-+
-+ DWC_CCLIB
-+ DWC_CRYPTOLIB
-+ DWC_NOTIFYLIB
-+ DWC_UTFLIB
-+
-+A DWC_LIBMODULE #define has also been added. If this is not defined, then the
-+module code in dwc_common_linux.c is not compiled in. This allows linking the
-+library code directly into a driver module, instead of as a standalone module.

-+

-+ * This file defines five types of data structures: singly-linked lists,
-+ * lists, simple queues, tail queues, and circular queues.
-+ *
-+ *
-+ * A singly-linked list is headed by a single forward pointer. The elements
-+ * are singly linked for minimum space and pointer manipulation overhead at
-+ * the expense of O(n) removal for arbitrary elements. New elements can be
-+ * added to the list after an existing element or at the head of the list.
-+ * Elements being removed from the head of the list should use the explicit
-+ * macro for this purpose for optimum efficiency. A singly-linked list may
-+ * only be traversed in the forward direction. Singly-linked lists are ideal
-+ * for applications with large datasets and few or no removals or for
-+ * implementing a LIFO queue.
-+ *
-+ * A list is headed by a single forward pointer (or an array of forward
-+ * pointers for a hash table header). The elements are doubly linked
-+ * so that an arbitrary element can be removed without a need to
-+ * traverse the list. New elements can be added to the list before
-+ * or after an existing element or at the head of the list. A list
-+ * may only be traversed in the forward direction.
-+ *
-+ * A simple queue is headed by a pair of pointers, one the head of the
-+ * list and the other to the tail of the list. The elements are singly
-+ * linked to save space, so elements can only be removed from the
-+ * head of the list. New elements can be added to the list before or after
-+ * an existing element, at the head of the list, or at the end of the
-+ * list. A simple queue may only be traversed in the forward direction.
-+ *
-+ * A tail queue is headed by a pair of pointers, one to the head of the
-+ * list and the other to the tail of the list. The elements are doubly
-+ * linked so that an arbitrary element can be removed without a need to
-+ * traverse the list. New elements can be added to the list before or
-+ * after an existing element, at the head of the list, or at the end of
-+ * the list. A tail queue may be traversed in either direction.
-+ *
-+ * A circle queue is headed by a pair of pointers, one to the head of the
-+ * list and the other to the tail of the list. The elements are doubly
-+ * linked so that an arbitrary element can be removed without a need to
-+ * traverse the list. New elements can be added to the list before or after
-+ * an existing element, at the head of the list, or at the end of the list.
-+ * A circle queue may be traversed in either direction, but has a more
-+ * complex end of list detection.
-+ *
-+ * For details on the use of these macros, see the queue(3) manual page.

-+/** @file
-+ *
-+ * A simple implementation of the Observer pattern. Any "module" can
-+ * register as an observer or notifier. The notion of "module" is abstract and
-+ * can mean anything used to identify either an observer or notifier. Usually
-+ * it will be a pointer to a data structure which contains some state, ie an
-+ * object.
-+ *
-+ * Before any notifiers can be added, the global notification manager must be
-+ * brought up with dwc_alloc_notification_manager().
-+ * dwc_free_notification_manager() will bring it down and free all resources.
-+ * These would typically be called upon module load and unload. The
-+ * notification manager is a single global instance that handles all registered
-+ * observable modules and observers so this should be done only once.
-+ *
-+ * A module can be observable by using Notifications to publicize some general
-+ * information about it's state or operation. It does not care who listens, or
-+ * even if anyone listens, or what they do with the information. The observable
-+ * modules do not need to know any information about it's observers or their
-+ * interface, or their state or data.
-+ *
-+ * Any module can register to emit Notifications. It should publish a list of
-+ * notifications that it can emit and their behavior, such as when they will get
-+ * triggered, and what information will be provided to the observer. Then it
-+ * should register itself as an observable module. See dwc_register_notifier().
-+ *
-+ * Any module can observe any observable, registered module, provided it has a
-+ * handle to the other module and knows what notifications to observe. See
-+ * dwc_add_observer().
-+ *
-+ * A function of type dwc_notifier_callback_t is called whenever a notification
-+ * is triggered with one or more observers observing it. This function is
-+ * called in it's own process so it may sleep or block if needed. It is
-+ * guaranteed to be called sometime after the notification has occurred and will
-+ * be called once per each time the notification is triggered. It will NOT be
-+ * called in the same process context used to trigger the notification.
-+ *
-+ * @section Limitiations
-+ *
-+ * Keep in mind that Notifications that can be triggered in rapid sucession may
-+ * schedule too many processes too handle. Be aware of this limitation when
-+ * designing to use notifications, and only add notifications for appropriate
-+ * observable information.
-+ *
-+ * Also Notification callbacks are not synchronous. If you need to synchronize
-+ * the behavior between module/observer you must use other means. And perhaps
-+ * that will mean Notifications are not the proper solution.

-+/* @mainpage DWC Portability and Common Library
-+ *
-+ * This is the documentation for the DWC Portability and Common Library.
-+ *
-+ * @section intro Introduction
-+ *
-+ * The DWC Portability library consists of wrapper calls and data structures to
-+ * all low-level functions which are typically provided by the OS. The WUDEV
-+ * driver uses only these functions. In order to port the WUDEV driver, only
-+ * the functions in this library need to be re-implemented, with the same
-+ * behavior as documented here.
-+ *
-+ * The Common library consists of higher level functions, which rely only on
-+ * calling the functions from the DWC Portability library. These common
-+ * routines are shared across modules. Some of the common libraries need to be
-+ * used directly by the driver programmer when porting WUDEV. Such as the
-+ * parameter and notification libraries.
-+ *
-+ * @section low Portability Library OS Wrapper Functions
-+ *
-+ * Any function starting with DWC and in all CAPS is a low-level OS-wrapper that
-+ * needs to be implemented when porting, for example DWC_MUTEX_ALLOC(). All of
-+ * these functions are included in the dwc_os.h file.
-+ *
-+ * There are many functions here covering a wide array of OS services. Please
-+ * see dwc_os.h for details, and implementation notes for each function.
-+ *
-+ * @section common Common Library Functions
-+ *
-+ * Any function starting with dwc and in all lowercase is a common library
-+ * routine. These functions have a portable implementation and do not need to
-+ * be reimplemented when porting. The common routines can be used by any
-+ * driver, and some must be used by the end user to control the drivers. For
-+ * example, you must use the Parameter common library in order to set the
-+ * parameters in the WUDEV module.
-+ *
-+ * The common libraries consist of the following:
-+ *
-+ * - Connection Contexts - Used internally and can be used by end-user. See dwc_cc.h
-+ * - Parameters - Used internally and can be used by end-user. See dwc_params.h
-+ * - Notifications - Used internally and can be used by end-user. See dwc_notifier.h
-+ * - Lists - Used internally and can be used by end-user. See dwc_list.h
-+ * - Memory Debugging - Used internally and can be used by end-user. See dwc_os.h
-+ * - Modpow - Used internally only. See dwc_modpow.h
-+ * - DH - Used internally only. See dwc_dh.h
-+ * - Crypto - Used internally only. See dwc_crypto.h
-+ *
-+ *
-+ * @section prereq Prerequistes For dwc_os.h
-+ * @subsection types Data Types
-+ *
-+ * The dwc_os.h file assumes that several low-level data types are pre defined for the
-+ * compilation environment. These data types are:
-+ *
-+ * - uint8_t - unsigned 8-bit data type
-+ * - int8_t - signed 8-bit data type
-+ * - uint16_t - unsigned 16-bit data type
-+ * - int16_t - signed 16-bit data type
-+ * - uint32_t - unsigned 32-bit data type
-+ * - int32_t - signed 32-bit data type
-+ * - uint64_t - unsigned 64-bit data type
-+ * - int64_t - signed 64-bit data type
-+ *
-+ * Ensure that these are defined before using dwc_os.h. The easiest way to do
-+ * that is to modify the top of the file to include the appropriate header.
-+ * This is already done for the Linux environment. If the DWC_LINUX macro is
-+ * defined, the correct header will be added. A standard header <stdint.h> is
-+ * also used for environments where standard C headers are available.
-+ *
-+ * @subsection stdarg Variable Arguments
-+ *
-+ * Variable arguments are provided by a standard C header <stdarg.h>. it is
-+ * available in Both the Linux and ANSI C enviornment. An equivalent must be
-+ * provided in your enviornment in order to use dwc_os.h with the debug and
-+ * tracing message functionality.
-+ *
-+ * @subsection thread Threading
-+ *
-+ * WUDEV Core must be run on an operating system that provides for multiple
-+ * threads/processes. Threading can be implemented in many ways, even in
-+ * embedded systems without an operating system. At the bare minimum, the
-+ * system should be able to start any number of processes at any time to handle
-+ * special work. It need not be a pre-emptive system. Process context can
-+ * change upon a call to a blocking function. The hardware interrupt context
-+ * that calls the module's ISR() function must be differentiable from process
-+ * context, even if your processes are impemented via a hardware interrupt.
-+ * Further locking mechanism between process must exist (or be implemented), and
-+ * process context must have a way to disable interrupts for a period of time to
-+ * lock them out. If all of this exists, the functions in dwc_os.h related to
-+ * threading should be able to be implemented with the defined behavior.
-+ *

-+ * Gadget Zero only needs two bulk endpoints, and is an example of how you

-+ *
-+ * Hardware details are visible (see CONFIG_USB_ZERO_* below) but don't

-+ *
-+ * Use it with the Linux host/master side "usbtest" driver to get a basic
-+ * functional test of your device-side usb stack, or with "usb-skeleton".
-+ *
-+ * It supports two similar configurations. One sinks whatever the usb host
-+ * writes, and in return sources zeroes. The other loops whatever the host
-+ * writes back, so the host can read it. Module options include:
-+ *
-+ * buflen=N default N=4096, buffer size used
-+ * qlen=N default N=32, how many buffers in the loopback queue
-+ * loopdefault default false, list loopback config first
-+ *
-+ * Many drivers will only have one configuration, letting them be much
-+ * simpler if they also don't support high speed operation (like this

-+ * The Core Interface Layer provides basic services for accessing and
-+ * managing the DWC_otg hardware. These services are used by both the
-+ * Host Controller Driver and the Peripheral Controller Driver.
-+ *
-+ * The CIL manages the memory map for the core so that the HCD and PCD
-+ * don't have to do this separately. It also handles basic tasks like
-+ * reading/writing the registers and data FIFOs in the controller.
-+ * Some of the data access functions provide encapsulation of several
-+ * operations required to perform a task, such as writing multiple
-+ * registers to start a transfer. Finally, the CIL performs basic
-+ * services that are not specific to either the host or device modes
-+ * of operation. These services include management of the OTG Host
-+ * Negotiation Protocol (HNP) and Session Request Protocol (SRP). A
-+ * Diagnostic API is also provided to allow testing of the controller
-+ * hardware.
-+ *
-+ * The Core Interface Layer has the following requirements:
-+ * - Provides basic controller operations.
-+ * - Minimal use of OS services.
-+ * - The OS services used will be abstracted by using inline functions
-+ * or macros.

-+ * This FIQ implements functionality that performs split transactions on
-+ * the dwc_otg hardware without any outside intervention. A split transaction
-+ * is "queued" by nominating a specific host channel to perform the entirety
-+ * of a split transaction. This FIQ will then perform the microframe-precise
-+ * scheduling required in each phase of the transaction until completion.
-+ *
-+ * The FIQ functionality is glued into the Synopsys driver via the entry point
-+ * in the FSM enqueue function, and at the exit point in handling a HC interrupt
-+ * for a FSM-enabled channel.
-+ *
-+ * NB: Large parts of this implementation have architecture-specific code.
-+ * For porting this functionality to other ARM machines, the minimum is required:
-+ * - An interrupt controller allowing the top-level dwc USB interrupt to be routed
-+ * to the FIQ
-+ * - A method of forcing a software generated interrupt from FIQ mode that then
-+ * triggers an IRQ entry (with the dwc USB handler called by this IRQ number)
-+ * - Guaranteed interrupt routing such that both the FIQ and SGI occur on the same
-+ * processor core - there is no locking between the FIQ and IRQ (aside from
-+ * local_fiq_disable)

-+ * actions on the DWC_otg controller. It isolates the Function Driver
-+ * from the specifics of the controller by providing an API to the
-+ * Function Driver.
-+ *
-+ * The Peripheral Controller Driver for Linux will implement the
-+ * Gadget API, so that the existing Gadget drivers can be used.
-+ * (Gadget Driver is the Linux terminology for a Function Driver.)
-+ *
-+ * The Linux Gadget API is defined in the header file
-+ * <code><linux/usb_gadget.h></code>. The USB EP operations API is
-+ * defined in the structure <code>usb_ep_ops</code> and the USB
-+ * Controller API is defined in the structure

-+ * @file
-+ *
-+ * This file contains the data structures for accessing the DWC_otg core registers.
-+ *
-+ * The application interfaces with the HS OTG core by reading from and
-+ * writing to the Control and Status Register (CSR) space through the
-+ * AHB Slave interface. These registers are 32 bits wide, and the
-+ * addresses are 32-bit-block aligned.
-+ * CSRs are classified as follows:
-+ * - Core Global Registers
-+ * - Device Mode Registers
-+ * - Device Global Registers
-+ * - Device Endpoint Specific Registers
-+ * - Host Mode Registers
-+ * - Host Global Registers
-+ * - Host Port CSRs
-+ * - Host Channel Specific Registers
-+ *
-+ * Only the Core Global registers can be accessed in both Device and
-+ * Host modes. When the HS OTG core is operating in one mode, either
-+ * Device or Host, the application must not access registers from the
-+ * other mode. When the core switches from one mode to another, the
-+ * registers in the new mode of operation must be reprogrammed as they
-+ * would be after a power-on reset.

-MIME-Version: 1.0
-Content-Type: text/plain; charset=UTF-8

-bcm2708_fb : Implement blanking support using the mailbox property interface
-
-bcm2708_fb: Add pan and vsync controls
-
-bcm2708_fb: DMA acceleration for fb_copyarea
-
-Based on http://www.raspberrypi.org/phpBB3/viewtopic.php?p=62425#p62425
-Also used Simon's dmaer_master module as a reference for tweaking DMA
-settings for better performance.
-
-For now busylooping only. IRQ support might be added later.
-With non-overclocked Raspberry Pi, the performance is ~360 MB/s
-for simple copy or ~260 MB/s for two-pass copy (used when dragging
-windows to the right).
-
-In the case of using DMA channel 0, the performance improves
-to ~440 MB/s.
-
-For comparison, VFP optimized CPU copy can only do ~114 MB/s in
-the same conditions (hindered by reading uncached source buffer).

-
-bcm2708_fb: report number of dma copies
-
-Add a counter (exported via debugfs) reporting the
-number of dma copies that the framebuffer driver
-has done, in order to help evaluate different
-optimization strategies.
-
-Signed-off-by: Luke Diamand <luked@broadcom.com>
-
-bcm2708_fb: use IRQ for DMA copies
-
-The copyarea ioctl() uses DMA to speed things along. This
-was busy-waiting for completion. This change supports using
-an interrupt instead for larger transfers. For small
-transfers, busy-waiting is still likely to be faster.
-

-
-bcm2708: Make ioctl logging quieter
-
-video: fbdev: bcm2708_fb: Don't panic on error
-
-No need to panic the kernel if the video driver fails.
-Just print a message and return an error.
-
-Signed-off-by: Noralf Trønnes <noralf@tronnes.org>
-
-fbdev: bcm2708_fb: Add ARCH_BCM2835 support
-
-Add Device Tree support.
-Pass the device to dma_alloc_coherent() in order to get the
-correct bus address on ARCH_BCM2835.
-Use the new DMA legacy API header file.
-Including <mach/platform.h> is not necessary.
-
-Signed-off-by: Noralf Trønnes <noralf@tronnes.org>
-
-BCM270x_DT: Add bcm2708-fb device
-
-Add bcm2708-fb to Device Tree and don't add the
-platform device when booting in DT mode.
-
-Signed-off-by: Noralf Trønnes <noralf@tronnes.org>
-
-Cleanup of bcm2708_fb file to kernel coding standards
-
-Some minor change to function - remove a use of
-in_atomic, plus replacing various debug messages
-that manually specify the function name with
-("%s",.__func__)
-
-Signed-off-by: James Hughes <james.hughes@raspberrypi.org>
-
-video: bcm2708_fb: Try allocating on the ARM and passing to VPU
-
-Currently the VPU allocates the contiguous buffer for the
-framebuffer.
-Try an alternate path first where we use dma_alloc_coherent
-and pass the buffer to the VPU. Should the VPU firmware not
-support that path, then free the buffer and revert to the
-old behaviour of using the VPU allocation.

-Subject: [PATCH] fbdev: add FBIOCOPYAREA ioctl
-
-Based on the patch authored by Ali Gholami Rudi at
- https://lkml.org/lkml/2009/7/13/153
-
-Provide an ioctl for userspace applications, but only if this operation
-is hardware accelerated (otherwide it does not make any sense).
-
-Signed-off-by: Siarhei Siamashka <siarhei.siamashka@gmail.com>
-
-bcm2708_fb: Add ioctl for reading gpu memory through dma
-
-video: bcm2708_fb: Add compat_ioctl support.
-
-When using a 64 bit kernel with 32 bit userspace we need
-compat ioctl handling for FBIODMACOPY as one of the
-parameters is a pointer.

-Subject: [PATCH] dmaengine: Add support for BCM2708
-MIME-Version: 1.0
-Content-Type: text/plain; charset=UTF-8
-Content-Transfer-Encoding: 8bit
-
-Add support for DMA controller of BCM2708 as used in the Raspberry Pi.
-Currently it only supports cyclic DMA.
-
-Signed-off-by: Florian Meier <florian.meier@koalo.de>
-
-dmaengine: expand functionality by supporting scatter/gather transfers sdhci-bcm2708 and dma.c: fix for LITE channels
-
-DMA: fix cyclic LITE length overflow bug
-
-dmaengine: bcm2708: Remove chancnt affectations
-
-Mirror bcm2835-dma.c commit 9eba5536a7434c69d8c185d4bd1c70734d92287d:
-chancnt is already filled by dma_async_device_register, which uses the channel
-list to know how much channels there is.
-
-Since it's already filled, we can safely remove it from the drivers' probe
-function.
-
-Signed-off-by: Noralf Trønnes <noralf@tronnes.org>
-
-dmaengine: bcm2708: overwrite dreq only if it is not set
-
-dreq is set when the DMA channel is fetched from Device Tree.
-slave_id is set using dmaengine_slave_config().
-Only overwrite dreq with slave_id if it is not set.
-
-dreq/slave_id in the cyclic DMA case is not touched, because I don't
-have hardware to test with.
-
-Signed-off-by: Noralf Trønnes <noralf@tronnes.org>
-
-dmaengine: bcm2708: do device registration in the board file
-
-Don't register the device in the driver. Do it in the board file.
-
-Signed-off-by: Noralf Trønnes <noralf@tronnes.org>
-
-dmaengine: bcm2708: don't restrict DT support to ARCH_BCM2835
-
-Both ARCH_BCM2835 and ARCH_BCM270x are built with OF now.
-Add Device Tree support to the non ARCH_BCM2835 case.
-Use the same driver name regardless of architecture.
-
-Signed-off-by: Noralf Trønnes <noralf@tronnes.org>
-
-BCM270x_DT: add bcm2835-dma entry
-
-Add Device Tree entry for bcm2835-dma.
-The entry doesn't contain any resources since they are handled
-by the arch/arm/mach-bcm270x/dma.c driver.
-In non-DT mode, don't add the device in the board file.

-
-BCM270x: Add memory and irq resources to dmaengine device and DT
-
-Prepare for merging of the legacy DMA API arch driver dma.c
-with bcm2708-dmaengine by adding memory and irq resources both
-to platform file device and Device Tree node.
-Don't use BCM_DMAMAN_DRIVER_NAME so we don't have to include mach/dma.h

-
-dmaengine: bcm2708: Merge with arch dma.c driver and disable dma.c
-
-Merge the legacy DMA API driver with bcm2708-dmaengine.
-This is done so we can use bcm2708_fb on ARCH_BCM2835 (mailbox
-driver is also needed).
-
-Changes to the dma.c code:
-- Use BIT() macro.
-- Cutdown some comments to one line.
-- Add mutex to vc_dmaman and use this, since the dev lock is locked
- during probing of the engine part.
-- Add global g_dmaman variable since drvdata is used by the engine part.
-- Restructure for readability:
- vc_dmaman_chan_alloc()
- vc_dmaman_chan_free()
- bcm_dma_chan_free()
-- Restructure bcm_dma_chan_alloc() to simplify error handling.
-- Use device irq resources instead of hardcoded bcm_dma_irqs table.
-- Remove dev_dmaman_register() and code it directly.
-- Remove dev_dmaman_deregister() and code it directly.
-- Simplify bcm_dmaman_probe() using devm_* functions.
-- Get dmachans from DT if available.
-- Keep 'dma.dmachans' module argument name for backwards compatibility.
-
-Make it available on ARCH_BCM2835 as well.

-dmaengine: bcm2708: set residue_granularity field
-
-bcm2708-dmaengine supports residue reporting at burst level
-but didn't report this via the residue_granularity field.
-
-Without this field set properly we get playback issues with I2S cards.
-
-dmaengine: bcm2708-dmaengine: Fix memory leak when stopping a running transfer
-
-bcm2708-dmaengine: Use more DMA channels (but not 12)
-
-1) Only the bcm2708_fb drivers uses the legacy DMA API, and
-it requires a BULK-capable channel, so all other types
-(FAST, NORMAL and LITE) can be made available to the regular
-DMA API.
-
-2) DMA channels 11-14 share an interrupt. The driver can't
-handle this, so don't use channels 12-14 (12 was used, probably
-because it appears to have an interrupt, but in reality that
-interrupt is for activity on ANY channel). This may explain
-a lockup encountered when running out of DMA channels.
-
-The combined effect of this patch is to leave 7 DMA channels
-available + channel 0 for bcm2708_fb via the legacy API.
-

-
-dmaengine: bcm2708: Make legacy API available for bcm2835-dma
-
-bcm2708_fb uses the legacy DMA API, so in order to start using
-bcm2835-dma, bcm2835-dma has to support the legacy API. Make this
-possible by exporting bcm_dmaman_probe() and bcm_dmaman_remove().

-
-dmaengine: bcm2708: Change DT compatible string
-
-Both bcm2835-dma and bcm2708-dmaengine have the same compatible string.
-So change compatible to "brcm,bcm2708-dma".
-
-Signed-off-by: Noralf Trønnes <noralf@tronnes.org>
-
-dmaengine: bcm2708: Remove driver but keep legacy API
-
-Dropping non-DT support means we don't need this driver,
-but we still need the legacy DMA API.

-dma-bcm2708: Fix module compilation of CONFIG_DMA_BCM2708
-
-bcm2708-dmaengine.c defines functions like bcm_dma_start which are
-defined as well in dma-bcm2708.h as inline versions when
-CONFIG_DMA_BCM2708 is not defined. This works fine when
-CONFIG_DMA_BCM2708 is built in, but when it is selected as module build
-fails with redefinition errors because in the build system when
-CONFIG_DMA_BCM2708 is selected as module, the macro becomes
-CONFIG_DMA_BCM2708_MODULE.
-
-This patch makes the header use CONFIG_DMA_BCM2708_MODULE too when
-available.

-bcm2708-dmaengine: Use platform_get_irq
-
-The platform driver framework no longer creates IRQ resources for

-Subject: [PATCH] MMC: added alternative MMC driver
-MIME-Version: 1.0
-Content-Type: text/plain; charset=UTF-8
-Content-Transfer-Encoding: 8bit
-
-mmc: Disable CMD23 transfers on all cards
-
-Pending wire-level investigation of these types of transfers
-and associated errors on bcm2835-mmc, disable for now. Fallback of
-CMD18/CMD25 transfers will be used automatically by the MMC layer.
-
-Reported/Tested-by: Gellert Weisz <gellert@raspberrypi.org>
-
-mmc: bcm2835-mmc: enable DT support for all architectures
-
-Both ARCH_BCM2835 and ARCH_BCM270x are built with OF now.
-Enable Device Tree support for all architectures.

-mmc: bcm2835-mmc: fix probe error handling
-
-Probe error handling is broken in several places.
-Simplify error handling by using device managed functions.
-Replace pr_{err,info} with dev_{err,info}.

-bcm2835-mmc: Add option to disable some delays
-
-bcm2835-mmc: Add option to disable MMC_QUIRK_BLK_NO_CMD23
-
-bcm2835-mmc: Default to disabling MMC_QUIRK_BLK_NO_CMD23
-
-bcm2835-mmc: Adding overclocking option
-
-Allow a different clock speed to be substitued for a requested 50MHz.
-This option is exposed using the "overclock_50" DT parameter.
-Note that the mmc interface is restricted to EVEN integer divisions of
-250MHz, and the highest sensible option is 63 (250/4 = 62.5), the
-next being 125 (250/2) which is much too high.
-
-Use at your own risk.
-
-bcm2835-mmc: Round up the overclock, so 62 works for 62.5Mhz
-
-Also only warn once for each overclock setting.
-
-mmc: bcm2835-mmc: Make available on ARCH_BCM2835
-
-Make the bcm2835-mmc driver available for use on ARCH_BCM2835.

-bcm2835-mmc: Don't overwrite MMC capabilities from DT
-
-bcm2835-mmc: Don't override bus width capabilities from devicetree
-
-Take out the force setting of the MMC_CAP_4_BIT_DATA host capability
-so that the result read from devicetree via mmc_of_parse() is
-preserved.
-
-bcm2835-mmc: Only claim one DMA channel
-
-With both MMC controllers enabled there are few DMA channels left. The
-bcm2835-mmc driver only uses DMA in one direction at a time, so it
-doesn't need to claim two channels.

-(which currently has no DT parameter). The sd_overclock parameter
-already provides another way to achieve the same thing which should be
-equivalent in end result, but it is a bug not to support max-frequency

-mmc/bcm2835: Recover from MMC_SEND_EXT_CSD
-
-If the user issues an "mmc extcsd read", the SD controller receives
-what it thinks is a SEND_IF_COND command with an unexpected data block.
-The resulting operations leave the FSM stuck in READWAIT, a state which
-persists until the MMC framework resets the controller, by which point
-the root filesystem is likely to have been unmounted.
-
-A less heavyweight solution is to detect the condition and nudge the
-FSM by asserting the (self-clearing) FORCE_DATA_MODE bit.
-
-N.B. This workaround was essentially discovered by accident and without
-a full understanding the inner workings of the controller, so it is
-fortunate that the "fix" only modifies error paths.

-bcm2835-mmc: Fix DMA channel leak
-
-The BCM2835 MMC host driver requests a DMA channel on probe but neglects
-to release the channel in the probe error path and on driver unbind.
-
-I'm seeing this happen on every boot of the Compute Module 3: On first
-driver probe, DMA channel 2 is allocated and then leaked with a "could
-not get clk, deferring probe" message. On second driver probe, channel 4
-is allocated.
-
-Fix it.

-bcm2835-mmc: Fix struct mmc_host leak on probe
-
-The BCM2835 MMC host driver requests the bus address of the host's

-Fix it.

-
-bcm2835-mmc: Fix duplicate free_irq() on remove
-
-The BCM2835 MMC host driver requests its interrupt as a device-managed
-resource, so the interrupt is automatically freed after the driver is
-unbound.
-
-However on driver unbind, bcm2835_mmc_remove() frees the interrupt
-explicitly to avoid invocation of the interrupt handler after driver
-structures have been torn down.
-
-The interrupt is thus freed twice, leading to a WARN splat in
-__free_irq(). Fix by not requesting the interrupt as a device-managed
-resource.

-bcm2835-mmc: Handle mmc_add_host() errors

-bcm2835-mmc: Deduplicate reset of driver data on remove

-From: Phil Elwell <phil@raspberrypi.org>
-Date: Wed, 25 Mar 2015 17:49:47 +0000
-Subject: [PATCH] Adding bcm2835-sdhost driver, and an overlay to
- enable it
-
-BCM2835 has two SD card interfaces. This driver uses the other one.
-
-bcm2835-sdhost: Error handling fix, and code clarification
-
-bcm2835-sdhost: Adding overclocking option
-
-Allow a different clock speed to be substitued for a requested 50MHz.
-This option is exposed using the "overclock_50" DT parameter.
-Note that the sdhost interface is restricted to integer divisions of
-core_freq, and the highest sensible option for a core_freq of 250MHz
-is 84 (250/3 = 83.3MHz), the next being 125 (250/2) which is much too
-high.
-
-Use at your own risk.
-
-bcm2835-sdhost: Round up the overclock, so 62 works for 62.5Mhz
-
-Also only warn once for each overclock setting.
-
-bcm2835-sdhost: Improve error handling and recovery
-
-1) Expose the hw_reset method to the MMC framework, removing many
- internal calls by the driver.
-
-2) Reduce overclock setting on error.
-
-3) Increase timeout to cope with high capacity cards.
-
-4) Add properties and parameters to control pio_limit and debug.
-
-5) Reduce messages at probe time.
-
-bcm2835-sdhost: Further improve overclock back-off
-
-bcm2835-sdhost: Clear HBLC for PIO mode
-
-Also update pio_limit default in overlay README.
-
-bcm2835-sdhost: Add the ERASE capability
-
-See: https://github.com/raspberrypi/linux/issues/1076
-
-bcm2835-sdhost: Ignore CRC7 for MMC CMD1
-
-It seems that the sdhost interface returns CRC7 errors for CMD1,
-which is the MMC-specific SEND_OP_COND. Returning these errors to
-the MMC layer causes a downward spiral, but ignoring them seems
-to be harmless.
-
-bcm2835-mmc/sdhost: Remove ARCH_BCM2835 differences
-
-The bcm2835-mmc driver (and -sdhost driver that copied from it)
-contains code to handle SDIO interrupts in a threaded interrupt
-handler rather than waking the MMC framework thread. The change
-follows a patch from Russell King that adds the facility as the
-preferred way of working.
-
-However, the new code path is only present in ARCH_BCM2835
-builds, which I have taken to be a way of testing the waters
-rather than making the change across the board; I can't see
-any technical reason why it wouldn't be enabled for MACH_BCM270X
-builds. So this patch standardises on the ARCH_BCM2835 code,
-removing the old code paths.
-
-bcm2835-sdhost: Don't log timeout errors unless debug=1
-
-The MMC card-discovery process generates timeouts. This is
-expected behaviour, so reporting it to the user serves no purpose.
-Suppress the reporting of timeout errors unless the debug flag
-is on.
-
-bcm2835-sdhost: Add workaround for odd behaviour on some cards
-
-For reasons not understood, the sdhost driver fails when reading
-sectors very near the end of some SD cards. The problem could
-be related to the similar issue that reading the final sector
-of any card as part of a multiple read never completes, and the
-workaround is an extension of the mechanism introduced to solve
-that problem which ensures those sectors are always read singly.
-
-bcm2835-sdhost: Major revision
-
-This is a significant revision of the bcm2835-sdhost driver. It
-improves on the original in a number of ways:
-
-1) Through the use of CMD23 for reads it appears to avoid problems
- reading some sectors on certain high speed cards.
-2) Better atomicity to prevent crashes.
-3) Higher performance.
-4) Activity logging included, for easier diagnosis in the event
- of a problem.

-bcm2835-sdhost: Restore ATOMIC flag to PIO sg mapping
-
-Allocation problems have been seen in a wireless driver, and
-this is the only change which might have been responsible.
-
-SQUASH: bcm2835-sdhost: Only claim one DMA channel
-
-With both MMC controllers enabled there are few DMA channels left. The
-bcm2835-sdhost driver only uses DMA in one direction at a time, so it
-doesn't need to claim two channels.

-
-bcm2835-sdhost: Workaround for "slow" sectors
-
-Some cards have been seen to cause timeouts after certain sectors are
-read. This workaround enforces a minimum delay between the stop after
-reading one of those sectors and a subsequent data command.
-
-Using CMD23 (SET_BLOCK_COUNT) avoids this problem, so good cards will
-not be penalised by this workaround.

-
-bcm2835-sdhost: Firmware manages the clock divisor
-
-The bcm2835-sdhost driver hands control of the CDIV clock divisor
-register to matching firmware, allowing it to adjust to a changing
-core clock. This removes the need to use the performance governor or
-to enable io_is_busy on the on-demand governor in order to get the
-best SD performance.
-
-N.B. As SD clocks must be an integer divisor of the core clock, it is
-possible that the SD clock for "turbo" mode can be different (even
-lower) than "normal" mode.
-

-
-bcm2835-sdhost: Reset the clock in task context
-
-Since reprogramming the clock can now involve a round-trip to the
-firmware it must not be done at atomic context, and a tasklet
-is not a task.

-
-bcm2835-sdhost: Don't exit cmd wait loop on error
-
-The FAIL flag can be set in the CMD register before command processing
-is complete, leading to spurious "failed to complete" errors. This has
-the effect of promoting harmless CRC7 errors during CMD1 processing
-into errors that can delay and even prevent booting.
-
-Also:
-1) Convert the last KERN_ERROR message in the register dumping to
- KERN_INFO.
-2) Remove an unnecessary reset call from bcm2835_sdhost_add_host.

-mmc: bcm2835-sdhost: Support underclocking
-
-Support underclocking of the SD bus in two ways:
-1. using the max-frequency DT property (which currently has no DT
- parameter), and
-2. using the exiting sd_overclock parameter.
-
-The two methods differ slightly - in the former the MMC subsystem is
-aware of the underclocking, while in the latter it isn't - but the
-end results should be the same.

-mmc/bcm2835-sdhost: Recover from MMC_SEND_EXT_CSD
-
-If the user issues an "mmc extcsd read", the SD controller receives
-what it thinks is a SEND_IF_COND command with an unexpected data block.
-The resulting operations leave the FSM stuck in READWAIT, a state which
-persists until the MMC framework resets the controller, by which point
-the root filesystem is likely to have been unmounted.
-
-A less heavyweight solution is to detect the condition and nudge the
-FSM by asserting the (self-clearing) FORCE_DATA_MODE bit.
-
-N.B. This workaround was essentially discovered by accident and without
-a full understanding the inner workings of the controller, so it is
-fortunate that the "fix" only modifies error paths.
-
-See: https://github.com/raspberrypi/linux/issues/2728

-bcm2835-sdhost: Allow for sg entries that cross pages
-
-The dma_complete handling code calculates a virtual address for a page
-then adds an offset, but if the offset is more than a page and HIGHMEM
-is in use then the summed address could be in an unmapped (or just
-incorrect) page.
-
-The upstream SDHOST driver allows for this possibility - copy the code
-that does so.

-Subject: [PATCH] vc_mem: Add vc_mem driver for querying firmware
- memory addresses
-MIME-Version: 1.0
-Content-Type: text/plain; charset=UTF-8
-Content-Transfer-Encoding: 8bit
-

-BCM270x: Move vc_mem
-
-Make the vc_mem module available for ARCH_BCM2835 by moving it.
-
-Signed-off-by: Noralf Trønnes <noralf@tronnes.org>
-
-char: vc_mem: Fix up compat ioctls for 64bit kernel
-
-compat_ioctl wasn't defined, so 32bit user/64bit kernel
-always failed.
-VC_MEM_IOC_MEM_PHYS_ADDR was defined with parameter size
-unsigned long, so the ioctl cmd changes between sizes.
-
-Signed-off-by: Dave Stevenson <dave.stevenson@raspberrypi.org>
-
-char: vc_mem: Fix all coding style issues.
-
-Cleans up all checkpatch errors in vc_mem.c and vc_mem.h
-No functional change to the code.
-
-Signed-off-by: Dave Stevenson <dave.stevenson@raspberrypi.org>
-
-char: vc_mem: Delete dead code
-
-There are no error exists once device_create has succeeded, and
-therefore no need to call device_destroy from vc_mem_init.

-The read and write functions did not use the correct pointer offset
-when dealing with an odd number of bytes after a DMA transfer. Also,
-only handle the remaining odd bytes if the DMA transfer completed
-successfully.

-Use the proper enumerated type to clear up the warning. There is not
-actually a bug here because the enumerated types have the same integer

-DMA_MEM_TO_DEV = DMA_TO_DEVICE = 1

-Subject: [PATCH] Add Chris Boot's i2c driver
-MIME-Version: 1.0
-Content-Type: text/plain; charset=UTF-8
-Content-Transfer-Encoding: 8bit
-
-i2c-bcm2708: fixed baudrate
-
-Fixed issue where the wrong CDIV value was set for baudrates below 3815 Hz (for 250MHz bus clock).
-In that case the computed CDIV value was more than 0xffff. However the CDIV register width is only 16 bits.
-This resulted in incorrect setting of CDIV and higher baudrate than intended.
-Example: 3500Hz -> CDIV=0x11704 -> CDIV(16bit)=0x1704 -> 42430Hz
-After correction: 3500Hz -> CDIV=0x11704 -> CDIV(16bit)=0xffff -> 3815Hz
-The correct baudrate is shown in the log after the cdiv > 0xffff correction.
-
-Perform I2C combined transactions when possible
-
-Perform I2C combined transactions whenever possible, within the
-restrictions of the Broadcomm Serial Controller.
-
-Disable DONE interrupt during TA poll
-
-Prevent interrupt from being triggered if poll is missed and transfer
-starts and finishes.
-
-i2c: Make combined transactions optional and disabled by default
-
-i2c: bcm2708: add device tree support
-
-Add DT support to driver and add to .dtsi file.
-Setup pins in .dts file.
-i2c is disabled by default.
-
-Signed-off-by: Noralf Tronnes <notro@tronnes.org>
-
-bcm2708: don't register i2c controllers when using DT
-
-The devices for the i2c controllers are in the Device Tree.
-Only register devices when not using DT.
-
-Signed-off-by: Noralf Tronnes <notro@tronnes.org>
-
-I2C: Only register the I2C device for the current board revision
-
-i2c_bcm2708: Fix clock reference counting
-
-Fix grabbing lock from atomic context in i2c driver
-
-2 main changes:
-- check for timeouts in the bcm2708_bsc_setup function as indicated by this comment:
- /* poll for transfer start bit (should only take 1-20 polls) */
- This implies that the setup function can now fail so account for this everywhere it's called
-- Removed the clk_get_rate call from inside the setup function as it locks a mutex and that's not ok since we call it from under a spin lock.
-
-i2c-bcm2708: When using DT, leave the GPIO setup to pinctrl
-
-i2c-bcm2708: Increase timeouts to allow larger transfers
-
-Use the timeout value provided by the I2C_TIMEOUT ioctl when waiting
-for completion. The default timeout is 1 second.
-
-See: https://github.com/raspberrypi/linux/issues/260
-
-i2c-bcm2708/BCM270X_DT: Add support for I2C2
-
-The third I2C bus (I2C2) is normally reserved for HDMI use. Careless
-use of this bus can break an attached display - use with caution.
-
-It is recommended to disable accesses by VideoCore by setting
-hdmi_ignore_edid=1 or hdmi_edid_file=1 in config.txt.
-
-The interface is disabled by default - enable using the
-i2c2_iknowwhatimdoing DT parameter.
-
-bcm2708-spi: Don't use static pin configuration with DT
-
-Also remove superfluous error checking - the SPI framework ensures the
-validity of the chip_select value.
-
-i2c-bcm2708: Remove non-DT support
-
-Signed-off-by: Noralf Trønnes <noralf@tronnes.org>
-
-Set the BSC_CLKT clock streching timeout to 35ms as per SMBus specs.
-
-Fixes i2c_bcm2708: Write to FIFO correctly - v2 (#1574)
-
-* i2c: fix i2c_bcm2708: Clear FIFO before sending data
-
-Make sure FIFO gets cleared before trying to send
-data in case of a repeated start (COMBINED=Y).
-
-* i2c: fix i2c_bcm2708: Only write to FIFO when not full
-
-Check if FIFO can accept data before writing.
-To avoid a peripheral read on the last iteration of a loop,
-both bcm2708_bsc_fifo_fill and ~drain are changed as well.

-Subject: [PATCH] char: broadcom: Add vcio module
-MIME-Version: 1.0
-Content-Type: text/plain; charset=UTF-8
-Content-Transfer-Encoding: 8bit
-
-Add module for accessing the mailbox property channel through
-/dev/vcio. Was previously in bcm2708-vcio.
-
-Signed-off-by: Noralf Trønnes <noralf@tronnes.org>
-
-char: vcio: Add compat ioctl handling
-
-There was no compat ioctl handler, so 32 bit userspace on a
-64 bit kernel failed as IOCTL_MBOX_PROPERTY used the size
-of char*.
-
-Signed-off-by: Dave Stevenson <dave.stevenson@raspberrypi.org>
-
-char: vcio: Fail probe if rpi_firmware is not found.
-
-Device Tree is now the only supported config mechanism, therefore
-uncomment the block of code that fails the probe if the
-firmware node can't be found.
-
-Signed-off-by: Dave Stevenson <dave.stevenson@raspberrypi.org>
-
-drivers: char: vcio: Use common compat header
-
-The definition of compat_ptr is now common for most platforms, but
-requires the inclusion of <linux/compat.h>.
-
-Signed-off-by: Phil Elwell <phil@raspberrypi.com>
-
-char: vcio: Rewrite as a firmware node child
-
-The old vcio driver is a simple character device that manually locates
-the firmware driver. Initialising it before the firmware driver causes
-a failure, and no retries are attempted.
-
-Rewrite vcio as a platform driver that depends on a DT node for its
-instantiation and the location of the firmware driver, making use of
-the miscdevice framework to reduce the code size.
-
-N.B. Using miscdevice changes the udev SUBSYSTEM string, so a change
-to the companion udev rule is required in order to continue to set
-the correct device permissions, e.g.:
-
- KERNEL="vcio", GROUP="video", MODE="0660"
-
-See: https://github.com/raspberrypi/linux/issues/4620

-Subject: [PATCH] leds: Add the "input" trigger, for pwr_led
-
-The "input" trigger makes the associated GPIO an input. This is to support
-the Raspberry Pi PWR LED, which is driven by external hardware in normal use.
-
-N.B. pwr_led is not available on Model A or B boards.
-
-leds-gpio: Implement the brightness_get method
-
-The power LED uses some clever logic that means it is driven
-by a voltage measuring circuit when configured as input, otherwise
-it is driven by the GPIO output value. This patch wires up the
-brightness_get method for leds-gpio so that user-space can monitor
-the LED value via /sys/class/gpio/led1/brightness. Using the input
-trigger this returns an indication of the system power health,
-otherwise it is just whatever value the trigger has written most
-recently.

-Subject: [PATCH] Improve __copy_to_user and __copy_from_user
- performance
-
-Provide a __copy_from_user that uses memcpy. On BCM2708, use
-optimised memcpy/memmove/memcmp/memset implementations.
-
-arch/arm: Add mmiocpy/set aliases for memcpy/set
-
-See: https://github.com/raspberrypi/linux/issues/1082
-
-copy_from_user: CPU_SW_DOMAIN_PAN compatibility
-
-The downstream copy_from_user acceleration must also play nice with
-CONFIG_CPU_SW_DOMAIN_PAN.
-
-See: https://github.com/raspberrypi/linux/issues/1381
-
-Signed-off-by: Phil Elwell <phil@raspberrypi.org>
-
-Fix copy_from_user if BCM2835_FAST_MEMCPY=n
-
-The change which introduced CONFIG_BCM2835_FAST_MEMCPY unconditionally
-changed the behaviour of arm_copy_from_user. The page pinning code
-is not safe on ARMv7 if LPAE & high memory is enabled and causes
-crashes which look like PTE corruption.
-
-Make __copy_from_user_memcpy conditional on CONFIG_2835_FAST_MEMCPY=y
-which is really an ARMv6 / Pi1 optimization and not necessary on newer
-ARM processors.
-
-arm: fix mmap unlocks in uaccess_with_memcpy.c
-
-This is a regression that was added with the commit 192a4e923ef092924dd013e7326f2ec520ee4783 as of rpi-5.8.y, since that is when the move to the mmap locking API was introduced - d8ed45c5dcd455fc5848d47f86883a1b872ac0d0
-
-The issue is that when the patch to improve performance for the __copy_to_user and __copy_from_user functions were added for the Raspberry Pi, some of the mmaps were incorrectly mapped to write instead of read. This would cause a verity of issues, and in my case, prevent the booting of a squashfs filesystem on rpi-5.8-y and above. An example of the panic you would see from this can be seen at https://pastebin.com/raw/jBz5xCzL

-
-arch/arm: Add __memset alias to memset_rpi.S
-
-memset_rpi.S is an optimised memset implementation, but doesn't define
-__memset (which was just added to memset.S). As a result, building
-for the BCM2835 platform causes a link failure.
-
-Add __memset as yet another alias to our common implementation.
-

-arm: Fix custom rpi __memset32 and __memset64
-
-See: https://github.com/raspberrypi/linux/issues/4798
-
-Signed-off-by: Phil Elwell <phil@raspberrypi.com>
-
-arm: Fix annoying .eh_frame section warnings
-
-Replace the cfi directives with the UNWIND equivalents. This prevents
-the .eh_frame section from being created, eliminating the warnings.

-Subject: [PATCH] gpio-poweroff: Allow it to work on Raspberry Pi
-
-The Raspberry Pi firmware manages the power-down and reboot
-process. To do this it installs a pm_power_off handler, causing
-the gpio-poweroff module to abort the probe function.
-
-This patch introduces a "force" DT property that overrides that
-behaviour, and also adds a DT overlay to enable and control it.
-
-Note that running in an active-low configuration (DT parameter
-"active_low") requires a custom dt-blob.bin and probably won't
-allow a reboot without switching off, so an external inversion
-of the trigger signal may be preferable.

-Subject: [PATCH] Add support for all the downstream rpi sound card
- drivers
-MIME-Version: 1.0
-Content-Type: text/plain; charset=UTF-8
-Content-Transfer-Encoding: 8bit
-
-ASoC: Add support for Rpi-DAC
-
-ASoC: Add prompt for ICS43432 codec
-
-Without a prompt string, a config setting can't be included in a
-defconfig. Give CONFIG_SND_SOC_ICS43432 a prompt so that Pi soundcards
-can use the driver.
-
-Signed-off-by: Phil Elwell <phil@raspberrypi.org>
-
-Add IQaudIO Sound Card support for Raspberry Pi
-
-Set a limit of 0dB on Digital Volume Control
-
-The main volume control in the PCM512x DAC has a range up to
-+24dB. This is dangerously loud and can potentially cause massive
-clipping in the output stages. Therefore this sets a sensible
-limit of 0dB for this control.
-
-Allow up to 24dB digital gain to be applied when using IQAudIO DAC+
-
-24db_digital_gain DT param can be used to specify that PCM512x
-codec "Digital" volume control should not be limited to 0dB gain,
-and if specified will allow the full 24dB gain.
-
-Modify IQAudIO DAC+ ASoC driver to set card/dai config from dt
-
-Add the ability to set the card name, dai name and dai stream name, from
-dt config.
-
-Signed-off-by: DigitalDreamtime <clive.messer@digitaldreamtime.co.uk>
-
-IQaudIO: auto-mute for AMP+ and DigiAMP+
-
-IQAudIO amplifier mute via GPIO22. Add dt params for "one-shot" unmute
-and auto mute.
-
-Revision 2, auto mute implementing HiassofT suggestion to mute/unmute
-using set_bias_level, rather than startup/shutdown....
-"By default DAPM waits 5 seconds (pmdown_time) before shutting down
-playback streams so a close/stop immediately followed by open/start
-doesn't trigger an amp mute+unmute."
-
-Tested on both AMP+ (via DAC+) and DigiAMP+, with both options...
-
-dtoverlay=iqaudio-dacplus,unmute_amp
- "one-shot" unmute when kernel module loads.
-
-dtoverlay=iqaudio-dacplus,auto_mute_amp
- Unmute amp when ALSA device opened by a client. Mute, with 5 second delay
- when ALSA device closed. (Re-opening the device within the 5 second close
- window, will cancel mute.)
-
-Revision 4, using gpiod.
-
-Revision 5, clean-up formatting before adding mute code.
- - Convert tab plus 4 space formatting to 2x tab
- - Remove '// NOT USED' commented code
-
-Revision 6, don't attempt to "one-shot" unmute amp, unless card is
-successfully registered.

-Added support for HiFiBerry DAC+
-
-The driver is based on the HiFiBerry DAC driver. However HiFiBerry DAC+ uses
-a different codec chip (PCM5122), therefore a new driver is necessary.
-
-Add support for the HiFiBerry DAC+ Pro.
-
-The HiFiBerry DAC+ and DAC+ Pro products both use the existing bcm sound driver with the DAC+ Pro having a special clock device driver representing the two high precision oscillators.
-
-An addition bug fix is included for the PCM512x codec where by the physical size of the sample frame is used in the calculation of the LRCK divisor as it was found to be wrong when using 24-bit depth sample contained in a little endian 4-byte sample frame.
-
-Limit PCM512x "Digital" gain to 0dB by default with HiFiBerry DAC+
-
-24db_digital_gain DT param can be used to specify that PCM512x
-codec "Digital" volume control should not be limited to 0dB gain,
-and if specified will allow the full 24dB gain.
-
-Add dt param to force HiFiBerry DAC+ Pro into slave mode
-
-"dtoverlay=hifiberry-dacplus,slave"
-
-Add 'slave' param to use HiFiBerry DAC+ Pro in slave mode,
-with Pi as master for bit and frame clock.

-ASoC: pcm512x: revert downstream changes
-
-This partially reverts commit 185ea05465aac8bf02a0d2b2f4289d42c72870b7
-which was added by https://github.com/raspberrypi/linux/pull/1152
-
-The downstream pcm512x changes caused a regression, it broke normal
-use of the 24bit format with the codec, eg when using simple-audio-card.
-
-The actual bug with 24bit playback is the incorrect usage
-of physical_width in various drivers in the downstream tree
-which causes 24bit data to be transmitted with 32 clock
-cycles. So it's not the pcm512x that needs fixing, it's the
-soundcard drivers.

-New AudioInjector.net Pi soundcard with low jitter audio in and out.
-
-Contains the sound/soc/bcm ALSA machine driver and necessary alterations to the Kconfig and Makefile.
-Adds the dts overlay and updates the Makefile and README.
-Updates the relevant defconfig files to enable building for the Raspberry Pi.
-Thanks to Phil Elwell (pelwell) for the review, simple-card concepts and discussion. Thanks to Clive Messer for overlay naming suggestions.
-
-Added support for headphones, microphone and bclk_ratio settings.
-
-This patch adds headphone and microphone capability to the Audio Injector sound card. The patch also sets the bit clock ratio for use in the bcm2835-i2s driver. The bcm2835-i2s can't handle an 8 kHz sample rate when the bit clock is at 12 MHz because its register is only 10 bits wide which can't represent the ch2 offset of 1508. For that reason, the rate constraint is added.

-
-2. Fix the diagnostics in an error path of the soundcard driver to

-
-3. Move the declaration of the clock node in the overlay outside
-the I2C node to avoid warnings.
-
-4. Sort the overlay nodes so that dependencies are only to earlier
-fragments, in an attempt to get runtime dtoverlay application to

-ASoC: Add generic RPI driver for simple soundcards.
-
-The RPI simple sound card driver provides a generic ALSA SOC card driver
-supporting a variety of Pi HAT soundcards. The intention is to avoid
-the duplication of code for cards that can't be fully supported by
-the soc simple/graph cards but are otherwise almost identical.
-
-This initial commit adds support for the ADAU1977 ADC, Google VoiceHat,
-HifiBerry AMP, HifiBerry DAC and RPI DAC.

-ASoC: Create a generic Pi Hat WM8804 driver
-
-Reduce the amount of duplicated code by creating a generic driver for
-Pi Hat digi cards using the WM8804 codec.
-
-This replaces the
-Allo DigiOne, Hifiberry Digi/Pro, JustBoom Digi and IQAudIO Digi
-dedicate soundcard drivers with a generic driver.
-
-There are no significant changes to the runtime behavior of the drivers
-and end users should not have to change any configuration settings
-after upgrading.
-
-Minor changes
-* Check the return value of snd_soc_component_update_bits
-* Added some pr_debug tracing
-* Various checkpatch tidyups
-* Updated allodigi-one to use use 128FS at > 96 Khz. This appears to
- be an omission in the original driver code so followed the Hifiberry
- DAC driver approach.

-ASoC: Add support for AudioSense-Pi add-on soundcard
-
-AudioSense-Pi is a RPi HAT based on a TI's TLV320AIC32x4 stereo codec
-
-This hardware provides multiple audio I/O capabilities to the RPi.
-The codec connects to the RPi's SoC through the I2S Bus.
-
-The following devices can be connected through a 3.5mm jack
- 1. Line-In: Plain old audio in from mobile phones, PCs, etc.,
- 2. Mic-In: Connect a microphone
- 3. Line-Out: Connect the output to a speaker
- 4. Headphones: Connect a Headphone w or w/o microphones
-
-Multiple Inputs:
- It supports the following combinations
- 1. Two stereo Line-Inputs and a microphone
- 2. One stereo Line-Input and two microphones
- 3. Two stereo Line-Inputs, a microphone and
- one mono line-input (with h/w hack)
- 4. One stereo Line-Input, two microphones and
- one mono line-input (with h/w hack)

-
-The driver only defines a single DAI link and the code that tries

-as a CPU/platform driver doesn't make any sense.
-
-The DT overlay doesn't define a dmic property, so the code was never

-
-So drop the offending code to prevent issues if a dmic property
-should be added to the DT overlay.

-Subject: [PATCH] bcm2835-virtgpio: Virtual GPIO driver
-
-Add a virtual GPIO driver that uses the firmware mailbox interface to
-request that the VPU toggles LEDs.
-
-gpio: bcm-virt: Fix the get() method
-
-The get() method does not understand the on-the-wire encoding of the
-remote GPIO states, thinking they are simple on/off bits when they are
-really pairs of 16-bit counts. Rewrite the get() handler to return the
-value last written, which will eventually match the actual GPIO state
-if there are no other changes.
-
-See: https://github.com/raspberrypi/linux/issues/4638

-Subject: [PATCH] OF: DT-Overlay configfs interface
-
-This is a port of Pantelis Antoniou's v3 port that makes use of the
-new upstreamed configfs support for binary attributes.
-
-Original commit message:
-
-Add a runtime interface to using configfs for generic device tree overlay
-usage. With it its possible to use device tree overlays without having
-to use a per-platform overlay manager.
-
-Please see Documentation/devicetree/configfs-overlays.txt for more info.
-
-Changes since v2:
-- Removed ifdef CONFIG_OF_OVERLAY (since for now it's required)
-- Created a documentation entry
-- Slight rewording in Kconfig
-
-Changes since v1:
-- of_resolve() -> of_resolve_phandles().

-DT configfs: fix build error
-
-There is an error when compiling rpi-4.6.y branch:
- CC drivers/of/configfs.o
-drivers/of/configfs.c:291:21: error: initialization from incompatible pointer type [-Werror=incompatible-pointer-types]
- .default_groups = of_cfs_def_groups,
- ^
-drivers/of/configfs.c:291:21: note: (near initialization for 'of_cfs_subsys.su_group.default_groups.next')
-
-The .default_groups is linked list since commit
-1ae1602de028acaa42a0f6ff18d19756f8e825c6.
-This commit uses configfs_add_default_group to fix this problem.

-
-of: configfs: Use of_overlay_fdt_apply API call
-
-The published API to the dynamic overlay application mechanism now
-takes a Flattened Device Tree blob as input so that it can manage the
-lifetime of the unflattened tree. Conveniently, the new API call -
-of_overlay_fdt_apply - is virtually a drop-in replacement for
-create_overlay, which can now be deleted.

-+Howto use the configfs overlay interface.
-+
-+A device-tree configfs entry is created in /config/device-tree/overlays
-+and and it is manipulated using standard file system I/O.
-+Note that this is a debug level interface, for use by developers and
-+not necessarily something accessed by normal users due to the
-+security implications of having direct access to the kernel's device tree.
-+
-+* To create an overlay you mkdir the directory:
-+
-+ # mkdir /config/device-tree/overlays/foo
-+
-+* Either you echo the overlay firmware file to the path property file.
-+
-+ # echo foo.dtbo >/config/device-tree/overlays/foo/path
-+
-+* Or you cat the contents of the overlay to the dtbo file
-+
-+ # cat foo.dtbo >/config/device-tree/overlays/foo/dtbo
-+
-+The overlay file will be applied, and devices will be created/destroyed
-+as required.
-+
-+To remove it simply rmdir the directory.
-+
-+ # rmdir /config/device-tree/overlays/foo
-+
-+The rationalle of the dual interface (firmware & direct copy) is that each is
-+better suited to different use patterns. The firmware interface is what's
-+intended to be used by hardware managers in the kernel, while the copy interface
-+make sense for developers (since it avoids problems with namespaces).

-Subject: [PATCH] ARM: bcm2835: Set Serial number and Revision
-MIME-Version: 1.0
-Content-Type: text/plain; charset=UTF-8
-Content-Transfer-Encoding: 8bit
-
-The VideoCore bootloader passes in Serial number and
-Revision number through Device Tree. Make these available to
-userspace through /proc/cpuinfo.
-
-Mainline status:
-
-There is a commit in linux-next that standardize passing the serial
-number through Device Tree (string: /serial-number):
-ARM: 8355/1: arch: Show the serial number from devicetree in cpuinfo
-
-There was an attempt to do the same with the revision number, but it
-didn't get in:
-[PATCH v2 1/2] arm: devtree: Set system_rev from DT revision
-
-Signed-off-by: Noralf Trønnes <noralf@tronnes.org>

-Subject: [PATCH] dwc-otg: FIQ: Fix "bad mode in data abort handler"
-
-Create a semi-static mapping for the USB registers early in the boot
-process, before additional kernel threads are started, so all threads
-will have the mappings from the start. This avoids the need for
-data aborts to lazily update them.

-Subject: [PATCH] i2c-gpio: Also set bus numbers from reg property
-
-I2C busses can be assigned specific bus numbers using aliases in
-Device Tree - string properties where the name is the alias and the
-value is the path to the node. The current DT parameter mechanism
-does not allow property names to be derived from a parameter value
-in any way, so it isn't possible to generate unique or matching
-aliases for nodes from an overlay that can generate multiple
-instances, e.g. i2c-gpio.
-
-Work around this limitation (at least temporarily) by allowing
-the i2c adapter number to be initialised from the "reg" property
-if present.

-+Driver a GPIO line that can be used to turn the power off.
-+
-+The driver supports both level triggered and edge triggered power off.
-+At driver load time, the driver will request the given gpio line and
-+install a handler to power off the system. If the optional properties
-+'input' is not found, the GPIO line will be driven in the inactive
-+state. Otherwise its configured as an input.
-+
-+When the power-off handler is called, the gpio is configured as an
-+output, and drive active, so triggering a level triggered power off
-+condition. This will also cause an inactive->active edge condition, so
-+triggering positive edge triggered power off. After a delay of 100ms,
-+the GPIO is set to inactive, thus causing an active->inactive edge,
-+triggering negative edge triggered power off. After another 100ms
-+delay the GPIO is driver active again. If the power is still on and
-+the CPU still running after a 3000ms delay, a WARN_ON(1) is emitted.
-+
-+Required properties:
-+- compatible : should be "gpio-poweroff".
-+- gpios : The GPIO to set high/low, see "gpios property" in
-+ Documentation/devicetree/bindings/gpio/gpio.txt. If the pin should be
-+ low to power down the board set it to "Active Low", otherwise set
-+ gpio to "Active High".
-+
-+Optional properties:
-+- input : Initially configure the GPIO line as an input. Only reconfigure
-+ it to an output when the power-off handler is called. If this optional
-+ property is not specified, the GPIO is initialized as an output in its
-+ inactive state.
-+- active-delay-ms: Delay (default 100) to wait after driving gpio active
-+- inactive-delay-ms: Delay (default 100) to wait after driving gpio inactive
-+- timeout-ms: Time to wait before asserting a WARN_ON(1). If nothing is
-+ specified, 3000 ms is used.
-+- export : Export the GPIO line to the sysfs system
-+
-+Examples:
-+
-+gpio-poweroff {
-+ compatible = "gpio-poweroff";
-+ gpios = <&gpio 4 0>;

-Subject: [PATCH] irqchip: irq-bcm2835: Calc. FIQ_START at boot-time
-
-ad83c7cb2f37 ("irqchip/irq-bcm2836: Add support for DT interrupt polarity")
-changed the way that the BCM2836/7 local interrupts are mapped; instead
-of being pre-mapped they are now mapped on-demand. A side effect of this
-change is that the call to irq_of_parse_and_map from armctrl_of_init
-creates a new mapping, forming a gap between the IRQs and the FIQs. This
- gap breaks the FIQ<->IRQ mapping which up to now has been done by assuming:
-
-1) that the value of FIQ_START is the same as the number of normal IRQs
-that will be mapped (still true), and
-
-2) that this value is also the offset between an IRQ and its equivalent
-FIQ (which is no longer the case).
-
-Remove both assumptions by measuring the interval between the last IRQ
-and the last FIQ, passing it as the parameter to init_FIQ().
-

- hysteresis
-
-Step wise governor increases the mitigation level when the temperature
-goes above a threshold and will decrease the mitigation when the
-temperature falls below the threshold. If it were a case, where the
-temperature hovers around a threshold, the mitigation will be applied
-and removed at every iteration. This reaction to the temperature is
-inefficient for performance.
-
-The use of hysteresis temperature could avoid this ping-pong of
-mitigation by relaxing the mitigation to happen only when the
-temperature goes below this lower hysteresis value.

-The bInterval is set to 4 (i.e. 8 microframes => 1ms) and the only bit
-that the driver pays attention to is "link was reset". If there's a
-flapping status bit in that endpoint data, (such as if PHY negotiation

-
-Add the ability to interpret the high bits of the dreq specifier as
-flags to be included in the DMA_CS register. The motivation for this
-change is the ability to set the DISDEBUG flag for SD card transfers
-to avoid corruption when using the VPU debugger.

-Subject: [PATCH] media: tc358743: Check I2C succeeded during probe.
-
-The probe for the TC358743 reads the CHIPID register from
-the device and compares it to the expected value of 0.
-If the I2C request fails then that also returns 0, so
-the driver loads thinking that the device is there.
-
-Generally I2C communications are reliable so there is
-limited need to check the return value on every transfer,
-therefore only amend the one read during probe to check
-for I2C errors.

-+Broadcom BCM283x Camera Interface (Unicam)
-+------------------------------------------
-+
-+The Unicam block on BCM283x SoCs is the receiver for either
-+CSI-2 or CCP2 data from image sensors or similar devices.
-+
-+The main platform using this SoC is the Raspberry Pi family of boards.
-+On the Pi the VideoCore firmware can also control this hardware block,
-+and driving it from two different processors will cause issues.
-+To avoid this, the firmware checks the device tree configuration
-+during boot. If it finds device tree nodes called csi0 or csi1 then
-+it will stop the firmware accessing the block, and it can then
-+safely be used via the device tree binding.
-+
-+Required properties:
-+===================
-+- compatible : must be "brcm,bcm2835-unicam".
-+- reg : physical base address and length of the register sets for the
-+ device.
-+- interrupts : should contain the IRQ line for this Unicam instance.
-+- clocks : list of clock specifiers, corresponding to entries in
-+ clock-names property.
-+- clock-names : must contain an "lp" entry, matching entries in the
-+ clocks property.
-+
-+Unicam supports a single port node. It should contain one 'port' child node
-+with child 'endpoint' node. Please refer to the bindings defined in
-+Documentation/devicetree/bindings/media/video-interfaces.txt.
-+
-+Within the endpoint node the "remote-endpoint" and "data-lanes" properties
-+are mandatory.
-+Data lane reordering is not supported so the data lanes must be in order,
-+starting at 1. The number of data lanes should represent the number of
-+usable lanes for the hardware block. That may be limited by either the SoC or
-+how the platform presents the interface, and the lower value must be used.
-+
-+Lane reordering is not supported on the clock lane either, so the optional
-+property "clock-lane" will implicitly be <0>.
-+Similarly lane inversion is not supported, therefore "lane-polarities" will
-+implicitly be <0 0 0 0 0>.
-+Neither of these values will be checked.
-+
-+Example:
-+ csi1: csi1@7e801000 {
-+ compatible = "brcm,bcm2835-unicam";
-+ reg = <0x7e801000 0x800>,
-+ <0x7e802004 0x4>;
-+ interrupts = <2 7>;
-+ clocks = <&clocks BCM2835_CLOCK_CAM1>;
-+ clock-names = "lp";
-+
-+ port {
-+ csi1_ep: endpoint {
-+ remote-endpoint = <&tc358743_0>;
-+ data-lanes = <1 2>;
-+ };
-+ };
-+ };
-+
-+ i2c0: i2c@7e205000 {
-+ tc358743: csi-hdmi-bridge@0f {
-+ compatible = "toshiba,tc358743";
-+ reg = <0x0f>;
-+
-+ clocks = <&tc358743_clk>;
-+ clock-names = "refclk";
-+
-+ tc358743_clk: bridge-clk {
-+ compatible = "fixed-clock";
-+ #clock-cells = <0>;
-+ clock-frequency = <27000000>;
-+ };
-+
-+ port {
-+ tc358743_0: endpoint {
-+ remote-endpoint = <&csi1_ep>;
-+ clock-lanes = <0>;
-+ data-lanes = <1 2>;
-+ clock-noncontinuous;
-+ link-frequencies =
-+ /bits/ 64 <297000000>;
-+ };
-+ };
-+ };
-+ };

-Subject: [PATCH] media: tc358743: Return an appropriate colorspace
- from tc358743_set_fmt
-
-When calling tc358743_set_fmt, the code was calling tc358743_get_fmt
-to choose a valid format. However that sets the colorspace
-based on what was read back from the chip. When you set the format,
-then the driver would choose and program the colorspace based
-on the format code.
-
-The result was that if you called try or set format for UYVY
-when the current format was RGB3 then you would get told sRGB,
-and try RGB3 when current was UYVY and you would get told
-SMPTE170M.
-
-The value programmed into the chip is determined by this driver,
-therefore there is no need to read back the value. Return the
-colorspace based on the format set/tried instead.

- kernel
-
-The MMAL client_component field is used with the event
-mechanism to allow the client to identify the component for
-which the event is generated.
-The field is only 32bits in size, therefore we can't use a
-pointer to the component in a 64 bit kernel.
-
-Component handles are already held in an array per VCHI
-instance, so use the array index as the client_component handle
-to avoid having to create a new IDR for this purpose.

-Subject: [PATCH] usb: add plumbing for updating interrupt endpoint
- interval state
-
-xHCI caches device and endpoint data after the interface is configured,
-so an explicit command needs to be issued for any device driver wanting
-to alter the polling interval of an endpoint.
-
-Add usb_fixup_endpoint() to allow drivers to do this. The fixup must be
-called after calculating endpoint bandwidth requirements but before any
-URBs are submitted.
-
-If polling intervals are shortened, any bandwidth reservations are no
-longer valid but in practice polling intervals are only ever relaxed.
-
-Limit the scope to interrupt transfers for now.

-Subject: [PATCH] drivers: char: add chardev for mmap'ing the RPiVid
- control registers
-
-Based on the gpiomem driver, allow mapping of the decoder register
-spaces such that userspace can access control/status registers.
-This driver is intended for use with a custom ffmpeg backend accelerator
-prior to a v4l2 driver being written.

-
-driver: char: rpivid: Destroy the legacy device on remove
-
-The legacy name support created a new device that was never destroyed.
-If the driver was unloaded and reloaded, it failed due to the
-device already existing.
-
-Fixes: "75f1d14 driver: char: rpivid - also support legacy name"
-Signed-off-by: Dave Stevenson <dave.stevenson@raspberrypi.com>
-
-driver: char: rpivid: Clean up error handling use of ERR_PTR/IS_ERR
-
-The driver used an unnecessary intermediate void* variable so it
-only called ERR_PTR once to convert to the error value.
-
-Switch to converting as the error arises to remove these intermediate
-variables.
-
-Signed-off-by: Dave Stevenson <dave.stevenson@raspberrypi.com>
-
-driver: char: rpivid: Add error handling to the legacy device load
-
-The return value from device_create for the legacy device was never
-checked or handled. Add the required error handling.

- and MX3
-
-These wireless mouse/keyboard combo remote control devices specify
-multiple "wheel" events in their report descriptors. The wheel events
-are incorrectly defined and apparently map to accelerometer data, leading
-to spurious mouse scroll events being generated at an extreme rate when
-the device is moved.
-
-As a workaround, use HID_QUIRK_INCREMENT_USAGE_ON_DUPLICATE to mask
-feeding the extra wheel events to the input subsystem.

-Subject: [PATCH] net: bcmgenet: Workaround #2 for Pi4 Ethernet fail
-
-Some combinations of Pi 4Bs and Ethernet switches don't reliably get a
-DCHP-assigned IP address, leaving the unit with a self=assigned 169.254
-address. In the failure case, the Pi is left able to receive packets
-but not send them, suggesting that the MAC<->PHY link is getting into
-a bad state.
-
-It has been found empirically that skipping a reset step by the genet
-driver prevents the failures. No downsides have been discovered yet,
-and unlike the forced renegotiation it doesn't increase the time to
-get an IP address, so the workaround is enabled by default; add
-
- genet.skip_umac_reset=n
-
-to the command line to disable it.

-busy set of devices on the bus. The errors are benign, but throughput
-will suffer as the xHC will pause processing of transfers until the
-event ring is drained by the kernel. Expand the number of event TRB slots
-available by increasing the number of event ring segments in the ERST.
-
-Controllers have a hardware-defined limit as to the number of ERST
-entries they can process, so make the actual number in use
-min(ERST_MAX_SEGS, hw_max).

-
-media: i2c: imx258: Make image geometry meet sensor requirements
-
-The output image is defined as being 4208x3118 pixels in size.
-Y_ADD_STA register was set to 0, and Y_ADD_END to 3118, giving
-3119 lines total.
-
-The datasheet lists a requirement for Y_ADD_STA to be a multiple
-of a power of 2 depending on binning/scaling mode (2 for full pixel,
-4 for x2-bin/scale, 8 for (x2-bin)+(x2-subsample) or x4-bin, or 16
-for (x4-bin)+(x2-subsample)).
-(Y_ADD_END – Y_ADD_STA + 1) also has to be a similar power of 2.
-
-The current configuration for the full res modes breaks that second
-requirement, and we can't increase Y_ADD_STA to 1 to retain exactly
-the same field of view as that then breaks the first requirement.
-For the binned modes, they are worse off as 3118 is not a multiple of
-4.
-
-Increase the main mode to 4208x3120 so that it is the same FOV as the
-binned modes, with Y_ADD_STA at 0.
-Fix Y_ADD_STA and Y_ADD_END for the binned modes so that they meet the
-sensor requirements.
-
-This does change the Bayer order as the default configuration is for
-H&V flips to be enabled, so readout is from Y_STA_END to Y_ADD_STA,
-and this patch has changed Y_STA_END.

-media: i2c: imx258: Disable digital cropping on binned modes
-
-The binned modes set DIG_CROP_X_OFFSET and DIG_CROP_IMAGE_WIDTH
-to less than the full image, even though the image being captured
-is meant to be a scaled version of the full array size.
-
-Reduce X_OFFSET to 0, and increase IMAGE_WIDTH to the full array.

-
-The sensor supports H & V flips, so implement the relevant controls.
-Note that the Bayer order changes with these flips, therefore
-they set the V4L2_CTRL_FLAG_MODIFY_LAYOUT property.
-
-As we now support flips, remove the restriction of the sensor only
-probing if rotated 180 degrees, but do take that value and initialise
-VFLIP and HFLIP based on it.

-IMX258 wasn't doing that as register 0x350 (FRM_LENGTH_CTL)

- sensor
-
-media: i2c: imx290: set the format before VIDIOC_SUBDEV_G_FMT is called
-
-Commit d46cfdc86c30d5ec768924f0b1e2683c8d20b671 upstream.
-
-With the current driver 'media-ctl -p' issued right after the imx290 driver
-is loaded prints:
-pad0: Source
- [fmt:unknown/0x0]
-
-The format value of zero is due to the current_format field of the imx290
-struct not being initialized yet.
-
-As imx290_entity_init_cfg() calls imx290_set_fmt(), the current_mode field
-is also initialized, so the line which set current_mode to a default value
-in driver's probe() function is no longer needed.

-Subject: [PATCH] media: i2c: imx477: Support for the Sony IMX477
- sensor
-
-dt-bindings: media: i2c: Add IMX477 CMOS sensor binding
-
-Add YAML device tree binding for IMX477 CMOS image sensor.

-
-media: i2c: Add driver for Sony IMX477 sensor
-
-Adds a driver for the 12MPix Sony IMX477 CSI2 sensor.
-Whilst the sensor supports 2 or 4 CSI2 data lanes, this driver
-currently only supports 2 lanes.
-
-The following Bayer modes are currently available:
-
-4056x3040 12-bit @ 10fps
-2028x1520 12-bit (binned) @ 40fps
-2028x1050 12-bit (cropped/binned) @ 50fps
-1012x760 10-bit (scaled) @ 120 fps
-
-Signed-off-by: Naushir Patuck <naush@raspberrypi.com>
-
-media: i2c: imx477: Add support for adaptive frame control
-
-Use V4L2_CID_EXPOSURE_AUTO_PRIORITY to control if the driver should
-automatically adjust the sensor frame length based on exposure time,
-allowing variable frame rates and longer exposures.
-

-
-media: i2c: imx477: Return correct result on sensor id verification
-
-The test should return -EIO if the register read id does not match
-the expected sensor id.

-media: i2c: imx477: Selection compliance fixes
-
-To comply with the intended usage of the V4L2 selection target when
-used to retrieve a sensor image properties, adjust the rectangles
-returned by the imx477 driver.
-
-The top/left crop coordinates of the TGT_CROP rectangle were set to
-(0, 0) instead of (8, 16) which is the offset from the larger physical
-pixel array rectangle. This was also a mismatch with the default values
-crop rectangle value, so this is corrected. Found with v4l2-compliance.
-
-While at it, add V4L2_SEL_TGT_CROP_BOUNDS support: CROP_DEFAULT and
-CROP_BOUNDS have the same size as the non-active pixels are not readable
-using the selection API. Found with v4l2-compliance.
-
-This commit mirrors 543790f777ba1b3264c168c653db6d415e7c983f done for
-the imx219 sensor.

-
-The V4L2_CID_EXPOSURE_AUTO_PRIORITY was used to let the sensor control
-frame length (effectively framerate) based on the requested exposure
-time requested. Remove this feature as it is never used, and goes
-against how V4L2 likes to handle exposure and vblank controls.

-
-media: i2c: imx477: Add very long exposure control to the driver
-
-Add support for very long exposures by using the exposure multiplier
-register. Userland does not need to pass any additional controls to
-enable long exposures, it simply requests a larger vblank to extend the
-exposure control range appropriately.
-
-Currently, since hblank is fixed, a maximum of approximately 124 seconds
-of exposure time can be used. In a future change, hblank could also be
-controlled in userland to give over 200 seconds of exposure time.

-Save the format code in imx477_set_pad_format() when setting up a new

-+* Infineon irs1125 time of flight sensor
-+
-+The Infineon irs1125 is a time of flight digital image sensor with
-+an active array size of 352H x 286V. It is programmable through I2C
-+interface. The I2C address defaults to 0x3D, but can be reconfigured
-+to address 0x3C or 0x41 via I2C commands. Image data is sent through
-+MIPI CSI-2, which is configured as either 1 or 2 data lanes.
-+
-+Required Properties:
-+- compatible: value should be "infineon,irs1125" for irs1125 sensor
-+- reg: I2C bus address of the device
-+- clocks: reference to the xclk input clock.
-+- pwdn-gpios: reference to the GPIO connected to the reset pin.
-+ This is an active low signal to the iirs1125.
-+
-+The irs1125 device node should contain one 'port' child node with
-+an 'endpoint' subnode. For further reading on port node refer to
-+Documentation/devicetree/bindings/media/video-interfaces.txt.
-+
-+Endpoint node required properties for CSI-2 connection are:
-+- remote-endpoint: a phandle to the bus receiver's endpoint node.
-+- clock-lanes: should be set to <0> (clock lane on hardware lane 0)
-+- data-lanes: should be set to <1> or <1 2> (one or two lane CSI-2
-+ supported)
-+
-+Example:
-+ sensor@10 {
-+ compatible = "infineon,irs1125";
-+ reg = <0x3D>;
-+ #address-cells = <1>;
-+ #size-cells = <0>;
-+ clocks = <&irs1125_clk>;
-+ pwdn-gpios = <&gpio 5 0>;
-+
-+ irs1125_clk: camera-clk {
-+ compatible = "fixed-clock";
-+ #clock-cells = <0>;
-+ clock-frequency = <26000000>;
-+ };
-+
-+ port {
-+ sensor_out: endpoint {
-+ remote-endpoint = <&csiss_in>;
-+ clock-lanes = <0>;
-+ data-lanes = <1 2>;
-+ };
-+ };
-+ };

-Subject: [PATCH] Initialise rpi-firmware before clk-bcm2835
-
-The IMA (Integrity Measurement Architecture) looks for a TPM (Trusted
-Platform Module) having been registered when it initialises; otherwise
-it assumes there is no TPM. It has been observed on BCM2835 that IMA
-is initialised before TPM, and that initialising the BCM2835 clock
-driver before the firmware driver has the effect of reversing this
-order.
-
-Change the firmware driver to initialise at core_initcall, delaying the
-BCM2835 clock driver to postcore_initcall.
-

-Subject: [PATCH] of: overlay: Correct symbol path fixups
-
-When symbols from overlays are added to the live tree their paths must
-be rebased. The translated symbol is normally the result of joining
-the fragment-relative path (with a leading "/") to the target path
-(either copied directly from the "target-path" property or resolved
-from the phandle). This translation fails when the target is the root
-node (a common case for Raspberry Pi overlays) because the resulting
-path starts with a double slash. For example, if target-path is "/" and
-the fragment adds a node called "newnode", the label associated with
-that node will be assigned the path "//newnode", which can't be found
-in the tree.
-
-Fix the failure case by explicitly replacing a target path of "/" with
-an empty string.

-+V4L2_PIX_FMT_NV21_COL128
-+Formats with ½ horizontal and vertical chroma resolution. This format
-+has two planes - one for luminance and one for chrominance. Chroma
-+samples are interleaved. The difference to ``V4L2_PIX_FMT_NV12`` is the
-+memory layout. The image is split into columns of 128 bytes wide rather than
-+being in raster order.
-+
-+V4L2_PIX_FMT_NV12_10_COL128
-+Follows the same pattern as ``V4L2_PIX_FMT_NV21_COL128`` with 128 byte, but is
-+a 10bit format with 3 10-bit samples being packed into 4 bytes. Each 128 byte
-+wide column therefore contains 96 samples.
-+
-+
-+Description
-+===========
-+
-+This is the two-plane versions of the YUV 4:2:0 format where data is
-+grouped into 128 byte wide columns. The three components are separated into
-+two sub-images or planes. The Y plane has one byte per pixel and pixels
-+are grouped into 128 byte wide columns. The CbCr plane has the same width,
-+in bytes, as the Y plane (and the image), but is half as tall in pixels.
-+The chroma plane is also in 128 byte columns, reflecting 64 Cb and 64 Cr
-+samples.
-+
-+The chroma samples for a column follow the luma samples. If there is any
-+paddding, then that will be reflected via the selection API.
-+The luma height must be a multiple of 2 lines.
-+
-+The normal bytesperline is effectively fixed at 128. However the format
-+requires knowledge of the stride between columns, therefore the bytesperline
-+value has been repurposed to denote the number of 128 byte long lines between
-+the start of each column.
-+
-+**Byte Order.**

-+3 10-bit values are packed into 4 bytes as bits 9:0, 19:10, and 29:20, with
-+bits 30 & 31 unused. For the luma plane, bits 9:0 are Y0, 19:10 are Y1, and
-+29:20 are Y2. For the chroma plane the samples always come in pairs of Cr
-+and Cb, so it needs to be considered 6 values packed in 8 bytes.

-
-This is probably not the API we will want to add, but it
-should show what semantics are needed by drivers.
-
-The goal is to allow the OUTPUT (aka source) buffer and the
-controls associated to a request to be released from the request,
-and in particular return the OUTPUT buffer back to userspace,
-without signalling the media request fd.
-
-This is useful for devices that are able to pre-process
-the OUTPUT buffer, therefore able to release it before
-the decoding is finished. These drivers should signal
-the media request fd only after the CAPTURE buffer is done.

-Subject: [PATCH] staging: media: rpivid: Add Raspberry Pi V4L2 H265
- decoder
-
-This driver is for the HEVC/H265 decoder block on the Raspberry
-Pi 4, and conforms to the V4L2 stateless decoder API.
-
-Signed-off-by: John Cox <jc@kynesim.co.uk>
-
-staging: media: rpivid: Select MEDIA_CONTROLLER and MEDIA_CONTROLLER_REQUEST_API
-
-MEDIA_CONTROLLER_REQUEST_API is a hidden option. If rpivid depends on it,
-the user would need to first enable another driver that selects
-MEDIA_CONTROLLER_REQUEST_API, and only then rpivid would become available.
-
-By selecting it instead of depending on it, it becomes possible to enable
-rpivid without having to enable other potentially unnecessary drivers.

-media: rpivid: Remove the need to have num_entry_points set
-
-VAAPI H265 has num entry points but never sets it. Allow a VAAPI
-shim to work without requiring rewriting the VAAPI driver.
-num_entry_points can be calculated from the slice_segment_addr
-of the next slice so delay processing until we have that.
-
-Also includes some minor cosmetics.

-
-media: rpivid: Convert to MPLANE
-
-Use multi-planar interface rather than single plane interface. This
-allows dmabufs holding compressed data to be resized.
-
-Signed-off-by: John Cox <jc@kynesim.co.uk>
-
-media: rpivid: Add an enable count to irq claim Qs
-
-Add an enable count to the irq Q structures to allow the irq logic to
-block further callbacks if resources associated with the irq are not
-yet available.
-
-Signed-off-by: John Cox <jc@kynesim.co.uk>
-
-media: rpivid: Add a Pass0 to accumulate slices and rework job finish
-
-Due to overheads in assembling controls and requests it is worth having
-the slice assembly phase separate from the h/w pass1 processing. Create
-a queue to service pass1 rather than have the pass1 finished callback
-trigger the next slice job.
-
-This requires a rework of the logic that splits up the buffer and
-request done events. This code contains two ways of doing that, we use
-Ezequiel Garcias <ezequiel@collabora.com> solution, but expect that
-in the future this will be handled by the framework in a cleaner manner.
-
-Fix up the handling of some of the memory exhaustion crashes uncovered
-in the process of writing this code.

-media: rpivid: Fix H265 aux ent reuse of the same slot
-
-It is legitimate, though unusual, for an aux ent associated with a slot
-to be selected in phase 0 before a previous selection has been used and
-released in phase 2. Fix such that if the slot is found to be in use
-that the aux ent associated with it is reused rather than an new aux
-ent being created. This fixes a problem where when the first aux ent
-was released the second was lost track of.
-
-This bug spotted in Nick's testing. It may explain some other occasional,
-unreliable decode error reports where dmesg included "Missing DPB AUX
-ent" logging.

-media: rpivid: Update to compile with new hevc decode params

-media: rpivid: Make slice ctrl dynamic

-
-media: rpivid: Only create aux entries for H265 if needed

-Only create aux entries of mv info for frames where that info might

-media: rpivid: Avoid returning EINVAL to a G_FMT ioctl
-
-V4L2 spec says that G/S/TRY_FMT IOCTLs should never return errors for
-anything other than wrong buffer types. Improve the capture format

-to supported ones properly.

-
-media: rpivid: Ensure IRQs have completed before uniniting context
-
-Before uniniting the decode context sync with the IRQ queues to ensure
-that decode no longer has any buffers in use. This fixes a problem that
-manifested as ffmpeg leaking CMA buffers when it did a stream off on
-OUTPUT before CAPTURE, though in reality it was probably much more

-Subject: [PATCH] spi: Force CS_HIGH if GPIO descriptors are used
-
-Commit f3186dd87669 ("spi: Optionally use GPIO descriptors for CS GPIOs")
-amended of_spi_parse_dt() to always set SPI_CS_HIGH for SPI slaves whose
-Chip Select is defined by a "cs-gpios" devicetree property.
-
-This change breaks drivers whose probe functions set the mode field of
-the spi_device because in doing so they clear the SPI_CS_HIGH flag.
-
-Fix by setting SPI_CS_HIGH in spi_setup (under the same conditions as
-in of_spi_parse_dt()).
-
-See also: 83b2a8fe43bd ("spi: spidev: Fix CS polarity if GPIO descriptors are used")
-
-Fixes: f3186dd87669 ("spi: Optionally use GPIO descriptors for CS GPIOs")
-Signed-off-by: Phil Elwell <phil@raspberrypi.com>
-
-SQUASH: spi: Demote SPI_CS_HIGH warning to KERN_DEBUG
-
-This warning is unavoidable from a client's perspective and
-doesn't indicate anything wrong (just surprising).
-
-SQUASH with "spi: use_gpio_descriptor fixup moved to spi_setup"

-+Sensor Ancillary Metadata
-+
-+Description
-+===========
-+
-+This format describes ancillary data generated by a camera sensor and
-+transmitted over a stream on the camera bus. Sensor vendors generally have their
-+own custom format for this ancillary data. Some vendors follow a generic
-+CSI-2/SMIA embedded data format as described in the `CSI-2 specification.
-+<https://mipi.org/specifications/csi-2>`_
-+
-+The size of the embedded buffer is defined as a single line with a pixel width
-+width specified in bytes. This is obtained by a call to the
-+:c:type:`VIDIOC_SUBDEV_G_FMT` ioctl on the sensor subdevice where the ``pad``
-+field in :c:type:`v4l2_subdev_format` is set to 1. Note that this size is fixed
-+and cannot be modified with a call to :c:type:`VIDIOC_SUBDEV_S_FMT`.

-+BCM2835 ISP Driver
-+==================
-+
-+Introduction
-+------------
-+
-+The BCM2835 Image Sensor Pipeline (ISP) is a fixed function hardware pipeline
-+for performing image processing operations. Images are fed to the input
-+of the ISP through memory frame buffers. These images may be in various YUV,
-+RGB, or Bayer formats. A typical use case would have Bayer images obtained from
-+an image sensor by the BCM2835 Unicam peripheral, written to a memory
-+frame buffer, and finally fed into the input of the ISP. Two concurrent output
-+images may be generated in YUV or RGB format at different resolutions.
-+Statistics output is also generated for Bayer input images.
-+
-+The bcm2835-isp driver exposes the following media pads as V4L2 device nodes:
-+
-+.. tabularcolumns:: |l|l|l|l|
-+
-+.. cssclass: longtable

-Subject: [PATCH] zswap: Defer zswap initialisation
-
-Enabling zswap support in the kernel configuration costs about 1.5MB
-of RAM, even when zswap is not enabled at runtime. This cost can be
-reduced significantly by deferring initialisation (including pool
-creation) until the "enabled" parameter is set to true. There is a
-small cost to this in that some initialisation code has to remain in
-memory after the init phase, just in case they are needed later,
-but the total size increase is negligible.

-Subject: [PATCH] PCI: brcmstb: Add DT property to control L1SS
-
-The BRCM PCIe block has controls to enable control of the CLKREQ#
-signal by the L1SS, and to gate the refclk with the CLKREQ# input.
-These controls are mutually exclusive - the upstream code sets the
-latter, but some use cases require the former.
-
-Add a Device Tree property - brcm,enable-l1ss - to switch to the
-L1SS configuration.

-
-Instead of changing the exposure and framerate settings for all sequences,
-they can be changed for every sequence individually now. Therefore the
-IRS1125_CID_SAFE_RECONFIG ctrl has been removed and replaced by
-IRS1125_CID_SAFE_RECONFIG_S<seq_num>_EXPO and *_FRAME ctrls.
-
-The consistency check in the sequence ctrl IRS1125_CID_SEQ_CONFIG

-Subject: [PATCH] media: irs1125: Keep HW in sync after imager reset
-
-When closing the video device, the irs1125 is put in power down state.
-To keep V4L2 ctrls and the HW in sync, v4l2_ctrl_handler_setup is
-called after power up.
-
-The compound ctrl IRS1125_CID_MOD_PLL however has a default value
-of all zeros, which puts the imager into a non responding state.
-Thus, this ctrl is not written by the driver into HW after power up.
-The userspace has to take care to write senseful data.

-Subject: [PATCH] media: bcm2835-unicam: Driver for CCP2/CSI2 camera
- interface
-
-Add a driver for the Unicam camera receiver block on BCM283x processors.
-Compared to the bcm2835-camera driver present in staging, this driver
-handles the Unicam block only (CSI-2 receiver), and doesn't depend on
-the VC4 firmware running on the VPU.
-
-The commit is made up of a series of changes cherry-picked from the
-rpi-5.4.y branch of https://github.com/raspberrypi/linux/ with
-additional enhancements, forward-ported to the mainline kernel.

-+ * and TI CAL camera interface driver by
-+ * Benoit Parrot <bparrot@ti.com>
-+ *
-+ *
-+ * There are two camera drivers in the kernel for BCM283x - this one
-+ * and bcm2835-camera (currently in staging).
-+ *
-+ * This driver directly controls the Unicam peripheral - there is no
-+ * involvement with the VideoCore firmware. Unicam receives CSI-2 or
-+ * CCP2 data and writes it into SDRAM.
-+ * The only potential processing options are to repack Bayer data into an
-+ * alternate format, and applying windowing.
-+ * The repacking does not shift the data, so can repack V4L2_PIX_FMT_Sxxxx10P
-+ * to V4L2_PIX_FMT_Sxxxx10, or V4L2_PIX_FMT_Sxxxx12P to V4L2_PIX_FMT_Sxxxx12,
-+ * but not generically up to V4L2_PIX_FMT_Sxxxx16. The driver will add both
-+ * formats where the relevant formats are defined, and will automatically
-+ * configure the repacking as required.
-+ * Support for windowing may be added later.
-+ *
-+ * It should be possible to connect this driver to any sensor with a
-+ * suitable output interface and V4L2 subdevice driver.
-+ *
-+ * bcm2835-camera uses the VideoCore firmware to control the sensor,
-+ * Unicam, ISP, and all tuner control loops. Fully processed frames are
-+ * delivered to the driver by the firmware. It only has sensor drivers
-+ * for Omnivision OV5647, and Sony IMX219 sensors.
-+ *
-+ * The two drivers are mutually exclusive for the same Unicam instance.
-+ * The VideoCore firmware checks the device tree configuration during boot.
-+ * If it finds device tree nodes called csi0 or csi1 it will block the
-+ * firmware from accessing the peripheral, and bcm2835-camera will
-+ * not be able to stream data.

-Subject: [PATCH] media: bcm2835-unicam: Drop WARN on uing direct cache
- alias
-
-Pi 0&1 pass all ARM accesses through the VPU L2 cache, therefore
-the dma-ranges property sets the cache alias bits to other
-than the direct alias, hence this WARN was firing.
-
-It was overprotective coding, so assume that everything is OK
-with the dma-ranges, and remove the WARN.

-Subject: [PATCH] media: bcm2835-unicam: Always service interrupts
-
-From when bringing up the driver, there was a check in the isr
-to ignore interrupts (claiming them handled) should the driver
-not be streaming.
-
-The VPU now will not register a camera driver if it finds a
-CSI2 node enabled in device tree, therefore this flawed check is
-redundant.

-Subject: [PATCH] staging: vc04_services: Add new vc-sm-cma driver
-
-Add Broadcom VideoCore Shared Memory support.
-
-This new driver allows contiguous memory blocks to be imported
-into the VideoCore VPU memory map, and manages the lifetime of
-those objects, only releasing the source dmabuf once the VPU has
-confirmed it has finished with it.
-
-Signed-off-by: Dave Stevenson <dave.stevenson@raspberrypi.com>
-
-staging: vcsm-cma: Fix memory leak from not detaching dmabuf
-
-When importing there was a missing call to detach the buffer,
-so each import leaked the sg table entry.
-
-Actually the release process for both locally allocated and
-imported buffers is identical, so fix them to both use the same
-function.
-

-
-staging/vc-sm-cma: Avoid log spamming on Pi0/1 over cache alias.
-
-Pi 0/1 use the 0x80000000 cache alias as the ARM also sees the world
-through the VPU L2 cache.
-vc-sm-cma was trying to ensure it was in an uncached alias (0xc), and
-complaining on every allocation if it weren't. Reduce this logging.
-
-Signed-off-by: Dave Stevenson <dave.stevenson@raspberrypi.com>
-
-vc-sm-cma: Restore correct cache maintainance operations
-
-We have been using the more expensive flush operations rather than
-invalidate and clean since kernel rpi-5.9.y
-
-These are exposed with:
-52f1453513ba95084ab811a030032fe605b0cbe2 Re-expose some dmi APIs for use in VCSM
-
-But I believe that commit was dropped when (non-cma) vc-sm was dropped,
-and didn't get updated when the commit was restored

-Insert a break to fix a fallthrough warning from clang14. Since the
-fallthrough was to another break, this is a cosmetic change.

-+ * 3) Allocating buffers for use by the VPU.
-+ *
-+ * In the first and second cases the native handle is a dmabuf. Releasing the

-Subject: [PATCH] staging: vc04_services: Add a V4L2 M2M codec driver
-MIME-Version: 1.0
-Content-Type: text/plain; charset=UTF-8
-Content-Transfer-Encoding: 8bit
-
-This adds a V4L2 memory to memory device that wraps the MMAL
-video decode and video_encode components for H264 and MJPEG encode
-and decode, MPEG4, H263, and VP8 decode (and MPEG2 decode
-if the appropriate licence has been purchased).
-
-This patch squashes all the work done in developing the driver
-on the Raspberry Pi rpi-5.4.y kernel branch.
-Thanks to Kieran Bingham, Aman Gupta, Chen-Yu Tsai, and
-Marek Behún for their contributions. Please refer to the
-rpi-5.4.y branch for the full history.

-
-staging: bcm2835-codec: Allow decode res changed before STREAMON(CAPTURE)
-
-The V4L2 stateful video decoder API requires that you can STREAMON
-on only the OUTPUT queue, feed in buffers, and wait for the
-SOURCE_CHANGE event.
-This requires that we enable the MMAL output port at the same time
-as the input port, because the output port is the one that creates
-the SOURCE_CHANGED event.

-
-staging/bcm2835-codec: Do not send buffers to the VPU unless streaming
-
-With video decode we now enable both input and output ports on

-earlier than desired if they are queued befoer STREAMON.
-
-Check that the queue is streaming before sending buffers to the VPU.

-
-staging: bcm2835-codec: Format changed should trigger drain
-
-When a format changed event occurs, the spec says that it
-triggers an implicit drain, and that needs to be signalled
-via -EPIPE.
-
-For BCM2835, the format changed event happens at the point
-the format change occurs, so no further buffers exist from
-before the resolution changed point. We therefore signal the
-last buffer immediately.
-We don't have a V4L2 available to us at this point, so set
-the videobuf2 queue last_buffer_dequeued flag directly.
-
-Signed-off-by: Dave Stevenson <dave.stevenson@raspberrypi.com>
-
-staging: bcm2835-codec: Signal the firmware to stop on all changes
-
-The firmware defaults to not stopping video decode if only the
-pixel aspect ratio or colourspace change. V4L2 requires us
-to stop decoding on any change, therefore tell the firmware
-of the desire for this alternate behaviour.

-staging: bcm2835-codec: Queue flushed buffers instead of completing

-
-Signed-off-by: Dave Stevenson <dave.stevenson@raspberrypi.com>
-
-staging: bcm2835_codec: Correct flushing code for refcounting
-
-Completions don't reference count, so setting the completion
-on the first buffer returned and then not reinitialising it
-means that the flush function doesn't behave as intended.

-
-staging/bcm2835-codec: bytesperline for YUV420/YVU420 needs to be 64
-
-Matching https://github.com/raspberrypi/linux/pull/4419, the ISP
-block (which is also used on the input of the encoder, and output
-of the decoder) needs the base address of all planes to be aligned
-to multiples of 32. This includes the chroma planes of YUV420 and
-YVU420.
-If the height is only a multiple of 2 (not 4), then you get an odd
-number of lines in the second plane, which means the 3rd plane
-starts at a multiple of bytesperline/2.
-
-Set the minimum bytesperline alignment to 64 for those formats
-so that the plane alignment is always right.
-
-Signed-off-by: Dave Stevenson <dave.stevenson@raspberrypi.com>
-
-staging/bcm2835-codec: Allow a different stride alignment per role
-
-Deinterlace and decode aren't affected in the same way as encode
-and ISP by the alignment requirement on 3 plane YUV420.
-Decode would be affected, but it always aligns the height up to
-a macroblock, and uses the selection API to reflect that.

-Add in the facility to set the bytesperline alignment per role.

-
-bcm2835-codec: Return empty buffers to the VPU instead of queueing to vbuf2
-
-The encoder can skip frames totally should rate control overshoot
-the target bitrate too far. In this situation it generates an
-output buffer of length 0.
-V4L2 treats a buffer of length 0 as an end of stream flag, which is
-not appropriate in this case, therefore we can not return that buffer
-to the client.
-
-The driver was returning the buffer to videobuf2 in the QUEUED state,
-however that buffer was then not dequeued again, so the number of
-buffers was reduced each time this happened. In the pathological
-case of using GStreamer's videotestsrc in mode 1 for noise, this happens
-sufficiently frequently to totally stall the pipeline.

-If the port is still enabled then return the buffer straight back to

-Subject: [PATCH] staging: vc04_services: ISP: Add a more complex ISP
- processing component
-
-Driver for the BCM2835 ISP hardware block. This driver uses the MMAL
-component to program the ISP hardware through the VC firmware.
-
-The ISP component can produce two video stream outputs, and Bayer
-image statistics. This can't be encompassed in a simple V4L2
-M2M device, so create a new device that registers 4 video nodes.
-
-This patch squashes all the development patches from the earlier
-rpi-5.4.y branch into one
-
-Signed-off-by: Naushir Patuck <naush@raspberrypi.com>

-Subject: [PATCH] gpio: Add gpio-fsm driver
-
-The gpio-fsm driver implements simple state machines that allow GPIOs
-to be controlled in response to inputs from other GPIOs - real and
-soft/virtual - and time delays. It can:
-+ create dummy GPIOs for drivers that demand them,
-+ drive multiple GPIOs from a single input, with optional delays,
-+ add a debounce circuit to an input,
-+ drive pattern sequences onto LEDs
-etc.

-
-gpio-fsm: Rename 'num-soft-gpios' to avoid warning
-
-As of 5.10, the Device Tree parser warns about properties that look
-like references to "suppliers" of various services. "num-soft-gpios"
-resembles a declaration of a GPIO called "num-soft", causing the value
-to be interpreted as a phandle, the owner of which is checked for a
-"#gpio-cells" property.
-
-To avoid this warning, rename the gpio-fsm property to "num-swgpios".
-

-
-gpio-fsm: Show state info in /sys/class/gpio-fsm
-
-Add gpio-fsm sysfs entries under /sys/class/gpio-fsm. For each state
-machine show the current state, which state (if any) will be entered
-after a delay, and the current value of that delay.
-
-Signed-off-by: Phil Elwell <phil@raspberrypi.com>
-
-gpio-fsm: Fix shutdown timeout handling
-
-The driver is intended to jump directly to a shutdown state in the
-event of a timeout during shutdown, but the sense of the test was
-inverted.
-
-Signed-off-by: Phil Elwell <phil@raspberrypi.com>
-
-gpio-fsm: Clamp the delay time to zero
-
-The sysfs delay_ms value is calculated live, and it is possible for
-the time left to appear to be negative briefly if the timer handling
-hasn't completed. Ensure the displayed value never goes below zero,
-for the sake of appearances.

-Subject: [PATCH] firmware: raspberrypi: Add support for tryonce reboot
- flag
-
-Define a new mailbox (SET_REBOOT_FLAGS) which may be used to
-pass optional flags to the Raspberry Pi firmware that changes
-the behaviour of the bootloader and firmware during a reboot.
-
-Currently this just defines the 'tryboot' flag which causes
-the firmware to load tryboot.txt instead config.txt. This
-alternate configuration file can be used to specify the
-path of an alternate firmware and kernels allowing a fallback
-mechanism to be implemented for OS upgrades.

-Subject: [PATCH] PCI: brcmstb: Restore initial fundamental reset
-
-[1] replaced a single reset function with a pointer to one of two
-implementations, but also removed the call asserting the reset
-at the start of brcm_pcie_setup. Doing so breaks Raspberry Pis with
-VL805 XHCI controllers lacking dedicated SPI EEPROMs, which have been
-used for USB booting but then need to be reset so that the kernel
-can reconfigure them. The lack of a reset causes the firmware's loading
-of the EEPROM image to RAM to fail, breaking USB for the kernel.
-

-
-We now have the hardware I2C controller pinmuxed to the drive the
-display I2C, but this controller does not support clock stretching.
-The Atmel micro-controller in the panel requires clock stretching
-to allow it to prepare any data to be read.

-a delay between them for the Atmel to prepare the data.

-Subject: [PATCH] spi: bcm2835: Workaround/fix for zero-length
- transfers
-
-A relatively recent commit ([1]) contained optimisation for the PIO
-SPI FIFO-filling functions. The commit message includes the phrase
-"[t]he blind and counted loops are always called with nonzero count".
-This is technically true, but it is still possible for count to become
-zero before the loop is entered - if tfr->len is zero. Moving the loop
-exit condition to the end of the loop saves a few cycles, but results
-in a near-infinite loop should the revised count be zero on entry.
-
-Strangely, zero-lengthed transfers aren't filtered by the SPI framework
-and, even more strangely, the Python3 spidev library is triggering them
-for no obvious reason.
-
-Avoid the problem completely by bailing out of the main transfer
-function early if trf->len is zero, although there may be a case for
-moving the mitigation into the framework.
-
-See: https://github.com/raspberrypi/linux/issues/4100

- logic
-
-If multiple sets of interrupts occur simultaneously, it may be unsafe
-to swap buffers, as the hardware may already be re-using the current
-buffers. In such cases, avoid swapping buffers, and wait for the next
-opportunity at the Frame End interrupt to signal completion.
-
-Additionally, check the packet compare status when watching for frame
-end for buffers swaps, as this could also signify a frame end event.

-Subject: [PATCH] Assign crypto aliases to different AES implementation
- modules
-
-The kernel modules aes-neon-blk and aes-neon-bs perform poorly, at least on
-Cortex-A72 without crypto extensions. In fact, aes-arm64 outperforms them
-on benchmarks, despite it being a simpler implementation (only accelerating
-the single-block AES cipher).
-
-For modes of operation where multiple cipher blocks can be processed in
-parallel, aes-neon-bs outperforms aes-neon-blk by around 60-70% and aes-arm64
-is another 10-20% faster still. But the difference is even more marked with
-modes of operation with dependencies between neighbouring blocks, such as
-CBC encryption, which defeat parallelism: in these cases, aes-arm64 is
-typically around 250% faster than either aes-neon-blk or aes-neon-bs.
-
-The key trade-off with aes-arm64 is that the look-up tables are situated in
-RAM. This leaves them potentially open to cache timing attacks. The two other
-modules, by contrast, load the look-up tables into NEON registers and so are
-able to perform in constant time.
-
-This patch aims to load aes-arm64 more often.
-
-If none of the currently-loaded crypto modules implement a given algorithm,
-a new one is typically selected for loading using a platform-neutral alias
-describing the required algorithm. To enable users to still
-load aes-neon-blk or aes-neon-bs if they really want them, while still
-ensuring that aes-arm64 is usually selected, remove the aliases from
-aes-neonbs-glue.c and aes-glue.c and apply them to aes-cipher-glue.c, but
-still build the two NEON modules.
-
-Since aes-glue.c can also be used to build aes-ce-blk, leave them enabled
-if USE_V8_CRYPTO_EXTENSIONS is defined, to ensure they are selected if we
-in future use a CPU which has the crypto extensions enabled.
-
-Note that the algorithm priority specifiers are unchanged, so if
-aes-neon-bs is loaded at the same time as aes-arm64, the former will be
-used in preference. However, aes-neon-blk and aes-arm64 have tied priority,
-so whichever module was loaded first will be used (assuming aes-neon-bs is
-not loaded).

-media: i2c: ov9281: Remove override of subdev name
-
-From the original Rockchip driver, the subdev was renamed
-from the default to being "mov9281 <dev_name>" whereas the
-default would have been "ov9281 <dev_name>".
-
-Remove the override to drop back to the default rather than
-a vendor custom string.

-DMABUFs are all handled by videobuf2, so there is no reason not

-
-Note that this driver is still using the vmalloc allocator, so
-the buffers it allocates will not be compatible with the codec
-or ISP driver that require contiguous buffers. However this
-driver should be able to import the buffers allocated by them.

-Subject: [PATCH] staging: vc04_services: isp: Set the YUV420/YVU420
- format stride to 64 bytes
-
-The bcm2835 ISP requires the base address of all input/output planes to have 32
-byte alignment. Using a Y stride of 32 bytes would not guarantee that the V
-plane would fulfil this, e.g. a height of 650 lines would mean the V plane
-buffer is not 32 byte aligned for YUV420 formats.
-
-Having a Y stride of 64 bytes would ensure both U and V planes have a 32 byte
-alignment, as the luma height will always be an even number of lines.

-MIME-Version: 1.0
-Content-Type: text/plain; charset=UTF-8
-Content-Transfer-Encoding: 8bit
-
-The vidioc_enum_input() v4l2 ioctl is capable of returning
-sensor/input status as well. This is used in current
-GStreamer HEAD for signal detection [1].
-
-bcm2835-unicam does handle this syscall, but it didn't ask
-the subdevice driver about the input status. The input then
-appeared as always present.
-
-This commit adds the necessary query. There is a precedent for
-this - the R-Car VIN V4L2 driver does a similar call [2].

-Subject: [PATCH] usb: xhci: workaround for bogus SET_DEQ_PENDING
- endpoint state
-
-See https://github.com/raspberrypi/linux/issues/3981
-
-An unknown unsafe memory access can result in the ep_state variable
-in xhci_virt_ep being trampled with a stuck SET_DEQ_PENDING state
-despite successful completion of a Set TR Deq Pointer command.
-
-All URB enqueue/dequeue calls for the endpoint will fail in this state
-so no transfers are possible until the device is reconnected.
-
-As a workaround, clear the flag if we see it set and issue a new Set
-TR Deq command anyway - this should be harmless, as a prior Set TR Deq
-command will only have been issued in the Stopped state, and if the
-endpoint is Running then the controller is required to ignore it and
-respond with a Context State Error event TRB.

-
-Conditional on a new compatible string, change the pagelist encoding
-such that the top 24 bits are the pfn, leaving 8 bits for run length
-(-1), giving a 36-bit address range.
-
-Manage the split between addresses for the VPU and addresses for the
-40-bit DMA controller with a dedicated DMA device pointer that on non-
-BCM2711 platforms is the same as the main VCHIQ device. This allows
-the VCHIQ node to stay in the usual place in the DT.

-Subject: [PATCH] staging: vchiq_arm: Usa a DMA pool for small bulks
-
-During a bulk transfer we request a DMA allocation to hold the
-scatter-gather list. Most of the time, this allocation is small
-(<< PAGE_SIZE), however it can be requested at a high enough frequency
-to cause fragmentation and/or stress the CMA allocator (think time
-spent in compaction here, or during allocations elsewhere).
-
-Implement a pool to serve up small DMA allocations, falling back
-to a coherent allocation if the request is greater than
-VCHIQ_DMA_POOL_SIZE.

-Subject: [PATCH] staging: mmal-vchiq: Reset buffers_with_vpu on
- port_enable
-
-Should we go through the timeout failure case with port_disable
-not returning all buffers for whatever reason, the
-buffers_with_vpu counter gets left at a non-zero value, which
-will cause reference counting issues should the instance be
-reused.
-
-Reset the count when the port is enabled again, but before
-any buffers have been sent to the VPU.

-Subject: [PATCH] media/bcm2835-unicam: Parse pad numbers correctly
-
-The driver was making big assumptions about the source device
-using pad 0 and 1, which doesn't follow for more complex
-devices where Unicam's source device may be a sink device for
-something else.
-
-Read the pad numbers through media controller, and reference
-them appropriately.

-Subject: [PATCH] media/bcm2835-unicam: Add support for configuration
- via MC API
-
-Adds Media Controller API support for more complex pipelines.
-libcamera is about to switch to using this mechanism for configuring
-sensors.
-
-This can be enabled by either a module parameter, or device tree.
-
-Various functions have been moved to group video-centric and
-mc-centric functions together.
-
-Based on a similar conversion done to ti-vpe.

-
-media: bcm2835-unicam: Fixup for 5.18 and new get_mbus_config struct
-
-The number of active CSI2 data lanes has moved within the struct
-v4l2_mbus_config used by the get_mbus_config API call.
-Update the driver to match the changes in mainline.

-Subject: [PATCH] drivers: bcm2835_isp: Allow multiple users for the
- ISP driver.
-
-Add a second (identical) set of device nodes to allow concurrent use of the ISP
-hardware by another user. This change effectively creates a second state
-structure (struct bcm2835_isp_dev) to maintain independent state for the second
-user. Node and media entity names are appened with the instance index
-appropriately.
-
-Further users can be added by changing the BCM2835_ISP_NUM_INSTANCES define.

-Subject: [PATCH] usb: xhci: add VLI_TRB_CACHE_BUG quirk
-
-The VL805 fetches up to 4 transfer TRBs at a time. TRB reads don't cross
-a 64B boundary, and if a TRB is fetched and is not on a 64B boundary,
-the read is sized up to the next 64B boundary.
-
-However the VL805 implements a readahead prefetch for TRBs on a transfer
-ring. This fetches the next 64B after any TRB read has happened. Near
-the end of a ring segment, the prefetcher can read the first 64B of the
-next page in physical memory and this is where the behaviour causes a
-bug.
-
-The controller does not tag reads with which endpoint they are for, so
-if the start of the next page is a ring segment used by a victim
-endpoint, and the victim endpoint is about to fetch TRBs from the start
-of the segment, the victim endpoint will read from the prefetched data
-and not perform a read to main memory. If the data is stale, the ring
-cycle state bit may not be correct and the endpoint will silently halt.
-
-Adjust trbs_per_seg for transfer rings allocated for this controller.

-Subject: [PATCH] media: i2c: ov9281: Increase diff between VTS and max
- exposure
-
-The driver did allow the exposure to go up to VTS - 4 lines,
-but this would produce a visible line on 1280x800, and a stall of
-the sensor at 640x480.
-
-Whilst it appears to work with a difference of 5, the datasheet states
-there should be at least 25 lines difference between VTS and exposure,
-so use that value.

-Subject: [PATCH] drivers: bcm2835_unicam: Disable trigger mode
- operation
-
-On a Pi3 B/B+ platform the imx219 sensor frequently generates a single corrupt
-frame when the sensor first starts. This can either be a missing line, or
-invalid samples within the line. This only occurrs using the Unicam kernel
-driver.
-
-Disabling trigger mode elimiates this corruption. Since trigger mode is a
-legacy feature copied from the firmware driver and not expected to be needed,
-remove it. Tested on the Raspberry Pi cameras and shows no ill effects.

-If the first ov9281_read_reg() call fails, id_msb will be used

-practice because the value of id is not used when either call to
-ov9281_read_reg() fails, as the boolean OR will short circuit due to the
-ret condition being checked first. Regardless, it is not good to use
-variables uninitialized so silence the warning by initializing id_msb to
-0, as was done with id.

-The default clock-stretch timeout is 35 mS, which works well for

-longer. Rather than trying to prescribe a safe default for everyone,

- Panel
-
-The Geekworm MZP280 panel is a 480x640 (portrait) panel with a
-capacitive touch interface and a 40 pin header meant to interface
-directly with the Raspberry Pi. The screen is 2.8 inches diagonally,
-and there appear to be at least 4 distinct versions all with the same
-panel timings.
-
-Timings were derived from drivers posted on the github located here:
-https://github.com/tianyoujian/MZDPI/tree/master/vga
-
-Additional details about this panel family can be found here:

-Subject: [PATCH] drm/panel: Add panel driver for TDO Y17B based panels
-
-The Top DisplayOptoelectronics (TDO) T17B driver chip is used
-in the TL040HDS20CT panel (found in the Pimoroni HyperPixel4
-Square display) and potentially other displays.
-The driver chip supports SPI for configuration and DPI
-video data.

-Subject: [PATCH] usb: xhci: add a quirk for Superspeed bulk OUT
- transfers on VL805
-
-The VL805 has a bug in its internal FIFO space accounting that results
-in bulk OUT babble if a TRB in a large multi-element TD has a data
-buffer size that is larger than and not a multiple of wMaxPacketSize for
-the endpoint. If the downstream USB3.0 link is congested, or latency is
-increased through an intermediate hub, then the VL805 enters a suspected
-FIFO overflow condition and transmits repeated, garbled data to the
-endpoint.
-
-TDs with TRBs of exact multiples of wMaxPacketSize and smaller than
-wMaxPacketSize appear to be handled correctly, so split buffers at a
-1024-byte length boundary and put the remainder in a separate smaller
-TRB.

- vcsm buffer on stop_streaming
-
-On stop_streaming() the vcsm buffer handle gets released by the buffer cleanup
-code. This will subsequently cause and error if userland re-queues the same
-buffer on the next start_streaming() call.
-
-Remove this cleanup code and rely on the vb2_ops->buf_cleanup() call to do the
-cleanups instead.

-Subject: [PATCH] media: i2c: Rename ad5398 to ad5398_vcm
-
-There's already a regulator module called ad5398 that exposes
-this device through the regulator API. That is meaningless in
-the terms that it uses and how it maps to V4L2, so a new driver
-was added. However the module name collision wasn't noted, so
-rename it now.

-Subject: [PATCH] mm,page_alloc,cma: introduce a customisable threshold
- for allocating pages in cma
-
-On some platforms the cma area can be half the entire system memory,
-meaning that allocations start happening in the cma area immediately.
-This leads to fragmentation and subsequent fatal cma_alloc failures.
-
-We introduce an "alloc_in_cma_threshold" parameter which requires that
-this many sixteenths of the free pages must be in cma before it will
-try to use them. By default this is set to 12, but the previous
-behaviour can be restored by setting it to 8 on startup.

-The panel sends MIPI DCS commands during prepare and is expecting

-
-Set the prepare_prev_first flag so that the upstream DSI host

- recovery
-
-See https://github.com/raspberrypi/linux/issues/5019
-
-If an SD card has degraded performance such that IO operations time out
-then the MMC block layer will leak SG DMA mappings in the swiotlb during
-recovery. It retries the same SG and this causes the leak, as it is
-mapped twice - once in sdhci_pre_req() and again during single-block
-reads in sdhci_prepare_data().
-
-Resetting the card (including power-cycling if a regulator for vmmc is
-present) ought to be enough to recover a stuck state, so for now don't
-try single-block reads in the recovery path.

-Subject: [PATCH] media: i2c: arducam_64mp: Advertise embedded data
- node on media pad 1
-
-This commit updates the arducam_64mp driver to adverise support for
-embedded data streams.
-
-The arducam_64mp sensor subdevice overloads the media pad to differentiate
-between image stream (pad 0) and embedded data stream (pad 1) when
-performing the v4l2_subdev_pad_ops functions.

-snd_bcm2835: disable HDMI audio when vc4 is used (#3640)
-
-Things don't work too well when both the vc4 driver and the firmware
-driver are trying to control the same audio output:
-
-[ 763.569406] bcm2835_audio bcm2835_audio: vchi message timeout, msg=5
-
-Hence, when the vc4 HDMI driver is used, let it control audio. This is done
-by introducing a new device tree property to the audio node, and
-extending the vc4-kms-v3d overlays to set it appropriately.

- condtion
-
-If we get a simultaneous FS + FE interrupt for the same frame, it cannot be
-marked as completed and returned to userland as the framebuffer will be refilled
-by Unicam on the next sensor frame. Additionally, the timestamp will be set to 0
-as the FS interrupt handling code will not have run yet.
-
-To avoid these problems, the frame is considered dropped in the FE handler,
-and will be returned to userland on the subsequent sensor frame.

- overrun
-
-The Unicam hardware has been observed to cause a buffer overrun when using the
-dummy buffer as a circular buffer. The conditions that cause the overrun are not
-fully known, but it seems to occur when the memory bus is heavily loaded.
-
-To avoid the overrun, program the hardware with a buffer size of 0 when using
-the dummy buffer. This will cause overrun into the allocated dummy buffer, but
-avoid out of bounds writes.

-Subject: [PATCH] usb: xhci: expand mitigations for VLI_SS_BULK_OUT_BUG
- quirk
-
-The VL805 can cause data corruption if a SS Bulk OUT endpoint enters a
-flow-control condition and there are TRBs in the transfer ring that are
-not an integral size of wMaxPacket and the endpoint is behind one or more
-hubs.
-
-This is frequently the case encountered when FAT32 filesystems are
-present on mass-storage devices with cluster sizes of 1 sector, and the
-filesystem is being written to with an aggregate of small files.
-
-The initial implementation of this quirk separated TRBs that didn't
-adhere to this limitation into two - the first a multiple of wMaxPacket
-and the second the 512-byte remainder - in an attempt to force TD
-fragments to align with packet boundaries. This reduced the incidence
-rate of data corruption but did not resolve it.
-
-The fix as recommended by VIA is to disable bursts if this sequence of
-TRBs can occur.
-
-Limit turning off bursts to just USB mass-storage devices by searching
-the device's configuration for an interface with a class type of
-USB_CLASS_MASS_STORAGE.

-Subject: [PATCH] usb: xhci: account for num_trbs_free when
- invalidating TDs
-
-If a ring has a number of TDs enqueued past the dequeue pointer, and the
-URBs corresponding to these TDs are dequeued, then num_trbs_free isn't
-updated to show that these TDs have been converted to no-ops and
-effectively "freed". This means that num_trbs_free creeps downwards
-until the count is exhausted, which then triggers xhci_ring_expansion()
-and effectively leaks memory by infinitely growing the transfer ring.
-
-This is commonly encounted through the use of a usb-serial port where
-the port is repeatedly opened, read, then closed.
-
-Move the num_trbs_free crediting out of the Set TR Dequeue Pointer
-handling and into xhci_invalidate_cancelled_tds().
-
-There is a potential for overestimating the actual space on the ring if
-the ring is nearly full and TDs are arbitrarily enqueued by a device
-driver while it is dequeueing them, but dequeues are usually batched
-during device close/shutdown or endpoint error recovery.
-
-See https://github.com/raspberrypi/linux/issues/5088

-Subject: [PATCH] drivers: usb: dwc_otg: fix reference passing when
- checking bandwidth
-
-The pointer (struct usb_host_endpoint *)->hcpriv should contain a
-reference to dwc_otg_qh_t if the driver has already seen a URB submitted
-to this endpoint.
-
-It then checks whether the qh exists and is already in a schedule in
-order to decide whether to allocate periodic bandwidth or not. Passing a
-pointer to an offset inside of struct usb_host_endpoint instead of just
-the pointer means it dereferences bogus addresses.
-
-Rationalise (delete) a variable while we're at it.

- functions
-
-Configuring GCC to use task stack protector canaries means it will
-insert calls to check functions in FIQ code. This is bad, as a) the
-FIQ's stack is banked and b) the failure invokes __stack_chk_fail which
-eventually tries to call printk(). Printing to the console inside the
-FIQ is generally fatal.
-
-Add CFLAGS to stop this happening in FIQ code.
-
-Also catch one function where notrace wasn't specified.

-Subject: [PATCH] drm/vc4: hdmi: Fix hdmi_enable_4kp60 detection
-
-In order to support higher HDMI frequencies, users have to set the
-hdmi_enable_4kp60 parameter in their config.txt file.
-
-We were detecting this so far by calling clk_round_rate() on the core
-clock with the frequency we're supposed to run at when one of those
-modes is enabled. Whether or not the parameter was enabled could then be
-inferred by the returned rate since the maximum clock rate reported by
-the firmware was one of the side effect of setting that parameter.
-
-However, the recent clock rework we did changed what clk_round_rate()
-was returning to always return the minimum allowed, and thus this test
-wasn't reliable anymore.
-
-Let's use the new clk_get_max_rate() function to reliably determine the
-maximum rate allowed on that clock and fix the 4k@60Hz output.
-
-Fixes: e9d6cea2af1c ("clk: bcm: rpi: Run some clocks at the minimum rate allowed")

- code
-
-In order to support higher HDMI frequencies, users have to set the
-hdmi_enable_4kp60 parameter in their config.txt file.
-
-This will have the side-effect of raising the maximum of the core clock,
-tied to the HVS, and managed by the HVS driver.
-
-However, we are querying this in the HDMI driver by poking into the HVS
-structure to get our struct clk handle.
-
-Let's make this part of the HVS bind implementation to have all the core
-clock related setup in the same place.

-

-BCM54213PE is an Ethernet PHY that supports PTP hardware timestamping.
-BCM54210PW ia another Ethernet PHY, but one without PTP support.
-Unfortunately the two PHYs return the same ID when queried, so some
-extra information is required to determine whether the PHY is PTP-
-capable.
-
-There are two Raspberry Pi products that use these PHYs - Pi 4B and
-CM4 - and fortunately they use different PHY addresses, so use that as
-a differentiator. Choose to treat a PHY with the same ID but another
-address as a BCM54210PE, which seems more common.
-

-Subject: [PATCH] drm/vc4_hdmi: Allow hotplug detect to be forced
-
-See: https://forum.libreelec.tv/thread/24783-tv-avr-turns-back-on-right-after-turning-them-off
-
-While the kernel provides a :D flag for assuming device is connected,
-it doesn't stop this function from being called and generating a cec_phys_addr_invalidate
-message when hotplug is deasserted.
-
-That message provokes a flurry of CEC messages which for many users results in the TV
-switching back on again and it's very hard to get it to stay switched off.
-
-It seems to only occur with an AVR and TV connected but has been observed across a
-number of manufacturers.
-
-The issue started with https://github.com/raspberrypi/linux/pull/4371
-and this provides an optional way of getting back the old behaviour

-Subject: [PATCH] usb: xhci: add XHCI_VLI_HUB_TT_QUIRK
-
-The integrated USB2.0 hub in the VL805 chipset has a bug where it
-incorrectly determines the remaining available frame time before the
-host next sends a SOF packet with an incremented frame_number.
-
-See the USB2.0 specification sections 11.3 and 11.14.2.3.
-
-The hub's non-periodic TT handler can transmit the IN/OUT handshake
-token too late, so a following 64-byte DATA0/1 packet causes the ACK
-handshake to collide with the propagated SOF. This causes port babble.
-
-Avoid ringing doorbells for vulnerable endpoints during uFrame 7 if the
-TR is Idle to stop one source of babble. An IN transfer for a Running TR
-may happen at any time, so there's not much we can do about that.
-
-Ideally a hub firmware update to properly implement frame timeouts is
-needed, and to avoid spinning for up to 125us when submitting TDs to
-Idle rings.

-Subject: [PATCH] vc4_hdmi: Avoid log spam for audio start failure
-
-We regularly get dmesg error reports of:
-[ 18.184066] hdmi-audio-codec hdmi-audio-codec.3.auto: ASoC: error at snd_soc_dai_startup on i2s-hifi: -19
-[ 18.184098] MAI: soc_pcm_open() failed (-19)
-
-Currently I get 30 of these when booting to desktop.
-We always say, ignore they are harmless, but removing them would be good.
-
-A bit of investigation shows, for me, the errors are all generated by second, unused hdmi interface.
-
-It shows as an alsa device, and pulseaudio attempts to open it (numerous times), generating a kernel
-error message each time.
-
-systemctl --user restart pulseaudio.service generates 6 additional error messages.
-
-The error messages all come through:
-https://github.com/raspberrypi/linux/blob/a009a9c0d79dfec114ee5102ec3d3325a172c952/sound/soc/soc-pcm.c#L39
-
-which suggests returning ENOTSUPP, rather that ENODEV will be quiet. And indeed it is.
-
-Note: earlier kernels do not have the quiet ENOTSUPP, so additional cherry-picks will be needed to backport

-
-Since we've recently added a ton of tests, the list starts to be a bit
-of a mess and creates unneeded conflicts.
-
-Let's order it alphabetically.

-MIME-Version: 1.0
-Content-Type: text/plain; charset=UTF-8
-Content-Transfer-Encoding: 8bit
-
-As the number of kunit tests in KMS grows further, we start to have
-multiple test suites that, for example, need to register a mock DRM
-driver to interact with the KMS function they are supposed to test.
-
-Let's add a file meant to provide those kind of helpers to avoid
-duplication.

-Subject: [PATCH] drm/vc4: kms: Sort the CRTCs by output before
- assigning them
-
-On the vc4 devices (and later), the blending is done by a single device
-called the HVS. The HVS has three FIFO that can operate in parallel, and
-route their output to 6 CRTCs and 7 encoders on the BCM2711.
-
-Each of these CRTCs and encoders have some constraints on which FIFO
-they can feed from, so we need some code to take all those constraints
-into account and assign FIFOs to CRTCs.
-
-The problem can be simplified by assigning those FIFOs to CRTCs by
-ascending output index number. We had a comment mentioning it already,
-but we were never actually enforcing it.
-
-It was working still in most situations because the probe order is
-roughly equivalent, except for the (optional, and fairly rarely used on
-the Pi4) VEC which was last in the probe order sequence, but one of the
-earliest device to assign.
-
-This resulted in configurations that were rejected by our code but were
-still valid with a different assignment.
-
-We can fix this by making sure we assign CRTCs to FIFOs by ordering
-them by ascending HVS output index.
-

-
-It's fairly hard to figure out the instance of the CRTC affected by an
-atomic change using the default name.
-
-Since we can provide our own to the CRTC initialization functions, let's
-do so to make the debugging sessions easier.

-Subject: [PATCH] drm/vc4: crtc: Introduce a lower-level crtc init
- helper
-MIME-Version: 1.0
-Content-Type: text/plain; charset=UTF-8
-Content-Transfer-Encoding: 8bit
-
-The current vc4_crtc_init() helper assumes that we will be using
-hardware planes and calls vc4_plane_init().
-
-While it's a reasonable assumption, we'll want to mock the plane and
-thus provide our own. Let's create a helper that will take the plane as
-an argument.

-From: Maxime Ripard <maxime@cerno.tech>
-Date: Mon, 21 Nov 2022 17:04:31 +0100
-Subject: [PATCH] drm/vc4: tests: Fail the current test if we access a
- register
-
-Accessing a register when running under kunit is a bad idea since our
-device is completely mocked.
-
-Fail the current test if we ever access any of our hardware registers.

-Subject: [PATCH] drm/vc4: tests: Add unit test suite for the PV muxing
-
-The HVS to PixelValve muxing code is fairly error prone and has a bunch
-of arbitrary constraints due to the hardware setup.
-
-Let's create a test suite that makes sure that the possible combinations
-work and the invalid ones don't.

-+KUnit Tests
-+===========
-+
-+The VC4 Driver uses KUnit to perform driver-specific unit and
-+integration tests.
-+
-+These tests are using a mock driver and can be ran using the
-+command::
-+ ./tools/testing/kunit/kunit.py run \
-+ --kunitconfig=drivers/gpu/drm/vc4/tests/.kunitconfig \
-+ --cross_compile aarch64-linux-gnu- --arch arm64
-+
-+Parts of the driver that are currently covered by tests are:
-+ * The HVS to PixelValve dynamic FIFO assignment, for the BCM2835-7
-+ and BCM2711.

-Subject: [PATCH] dt: Correct cam_reg GPIO assignments for CM1&3.
-
-The standard instructions for wiring up cameras on CM1&3
-assign GPIOs for both the shutdown and LED pins on the
-camera connectors.
-The assignment in DT matched the LED wiring, not the shutdown
-line, so didn't control the camera power correctly.
-
-Update the base DT accordingly.

-Subject: [PATCH] media: dw9807-vcm: Add support for DW9817
- bidirectional VCM driver
-
-The DW9817 is effectively the same as DW9807 from a programming
-interface, however it drives +/-100mA instead of 0-100mA. This means
-that the power on ramp needs to take the lens from the midpoint, and
-power off return it there. It also changes the default position for
-the module.

-
-Uses the regulator notifier framework so that the current

-regulator powers it up. This means that should the VCM
-and sensor share a common regulator then starting the sensor
-will automatically restore the default position. If they
-have independent regulators then it will behave be powered
-up when the VCM subdev is opened.

-Subject: [PATCH] media/i2c: Add a driver for the Sony IMX708 image
- sensor
-
-The imx708 is a 12MP MIPI sensor with a 16:9 aspect ratio, here using
-two CSI-2 lanes. It is a "quad Bayer" sensor with all 3 modes offering
-10-bit output:
-
-12MP: 4608x2592 up to 14.35fps (full FoV)
-1080p: 2304x1296 up to 56.02fps (full FoV)
-720p: 1536x864 up to 120.12fps (cropped)
-
-This imx708 sensor driver is based heavily on the imx477 driver and
-has been tested on the Raspberry Pi platform using libcamera.

-Subject: [PATCH] net: phy: broadcom: Make LEDs 3+4 shadow LEDs 1+2
-
-CM4 uses BCM54210PE, which supports 2 additional LEDs, choosing LED3
-for the amber LED because it shows activity by default (LED4 is not
-connected). However, this makes it uncontrollable by the eth_led<n>
-dtparams which target LEDs 1+2.
-
-Solve the problem by making LEDs 3+4 mirror LEDs 1+2 (which is much
-simpler than adding baseboard-specific overrides, but comes with a
-risk of making one of the LEDs redundant).
-
-See: https://github.com/raspberrypi/linux/issues/5289

- RGB or YCbCr
-
-Add a custom property "Output format" that allows the overriding
-of the default colourspace choice in the way that the old
-firmware hdmi_pixel_encoding property did. If the chosen format is not
-supported, then it will still drop back to the older behaviour.
-
-This won't be acceptable to upstream, but it adds back the missing
-functionality of hdmi_pixel_encoding.

-
-bcm2835_mmc_probe() ignores errors returned by mmc_of_parse() and in
-particular ignores -EPROBE_DEFER, which may be returned if the power
-sequencing driver configured in the devicetree is compiled as a module.
-
-The user-visible result is that access to the SDIO device fails because

-Subject: [PATCH] drm/vc4: hvs: Defer dlist slots deallocation
-
-During normal operations, the cursor position update is done through an
-asynchronous plane update, which on the vc4 driver basically just
-modifies the right dlist word to move the plane to the new coordinates.
-
-However, when we have the overscan margins setup, we fall back to a
-regular commit when we are next to the edges. And since that commit
-happens to be on a cursor plane, it's considered a legacy cursor update
-by KMS.
-
-The main difference it makes is that it won't wait for its completion
-(ie, next vblank) before returning. This means if we have multiple
-commits happening in rapid succession, we can have several of them
-happening before the next vblank.
-
-In parallel, our dlist allocation is tied to a CRTC state, and each time
-we do a commit we end up with a new CRTC state, with the previous one
-being freed. This means that we free our previous dlist entry (but don't
-clear it though) every time a new one is being committed.
-
-Now, if we were to have two commits happening before the next vblank, we
-could end up freeing reusing the same dlist entries before the next
-vblank.
-
-Indeed, we would start from an initial state taking, for example, the
-dlist entries 10 to 20, then start a commit taking the entries 20 to 30
-and setting the dlist pointer to 20, and freeing the dlist entries 10 to
-20. However, since we haven't reach vblank yet, the HVS is still using
-the entries 10 to 20.
-
-If we were to make a new commit now, chances are the allocator are going
-to give the 10 to 20 entries back, and we would change their content to
-match the new state. If vblank hasn't happened yet, we just corrupted
-the active dlist entries.
-
-A first attempt to solve this was made by creating an intermediate dlist
-buffer to store the current (ie, as of the last commit) dlist content,
-that we would update each time the HVS is done with a frame. However, if
-the interrupt handler missed the vblank window, we would end up copying
-our intermediate dlist to the hardware one during the composition,
-essentially creating the same issue.
-
-Since making sure that our interrupt handler runs within a fixed,
-constrained, time window would require to make Linux a real-time kernel,
-this seems a bit out of scope.
-
-Instead, we can work around our original issue by keeping the dlist
-slots allocation longer. That way, we won't reuse a dlist slot while
-it's still in flight. In order to achieve this, instead of freeing the
-dlist slot when its associated CRTC state is destroyed, we'll queue it
-in a list.
-
-A naive implementation would free the buffers in that queue when we get
-our end of frame interrupt. However, there's still a race since, just
-like in the shadow dlist case, we don't control when the handler for
-that interrupt is going to run. Thus, we can end up with a commit adding
-an old dlist allocation to our queue during the window between our
-actual interrupt and when our handler will run. And since that buffer is
-still being used for the composition of the current frame, we can't free
-it right away, exposing us to the original bug.
-
-Fortunately for us, the hardware provides a frame counter that is
-increased each time the first line of a frame is being generated.
-Associating the frame counter the image is supposed to go away to the
-allocation, and then only deallocate buffers that have a counter below
-or equal to the one we see when the deallocation code should prevent the
-above race from occuring.

-Subject: [PATCH] vc4/hdmi: Always enable GCP with AVMUTE cleared
-
-See: https://forum.libreelec.tv/thread/24780-le-10-0-1-rpi4-no-picture-after-update-from-le-10-0-0
-
-Issue is some displays go blank at the point of firmware to kms handover.
-Plugging/unplugging hdmi cable, power cycling display, or switching standby off/on
-typically resolve this case.
-
-Finally managed to find a display that suffers from this, and track down the issue.
-
-The firmware uses AVMUTE in normal operation. It will set AVMUTE before disabling hdmi
-clocks and phy. It will clear AVMUTE after clocks and phy are set up for a new hdmi mode.
-
-But with the hdmi handover from firmware to kms, AVMUTE will be set by firmware.
-
-kms driver typically has no GCP packet (except for deep colour modes).
-The spec isn't clear on whether to consider the AVMUTE as continuing indefinitely
-in the absense of a GCP packet, or to consider that state to have ended.
-
-Most displays behave as we want, but there are a number (from mutiple manufacturers)
-which need to see AVMUTE cleared before displaying a picture.
-
-Lets just always enable GCP packet with AVMUTE cleared. That resolves the issue on
-problematic displays.
-
-From HDMI 1.4 spec:
-A CD field of zero (Color Depth not indicated) shall be used whenever the Sink does
-not indicate support for Deep Color. This value may also be used in Deep Color mode
-to transmit a GCP indicating only non-Deep Color information (e.g. AVMUTE).
-
-So use CD=0 where we were previously not enabling a GCP.

-Subject: [PATCH] kunit: Provide a static key to check if KUnit is
- actively running tests
-
-KUnit does a few expensive things when enabled. This hasn't been a
-problem because KUnit was only enabled on test kernels, but with a few
-people enabling (but not _using_) KUnit on production systems, we need a
-runtime way of handling this.
-
-Provide a 'kunit_running' static key (defaulting to false), which allows
-us to hide any KUnit code behind a static branch. This should reduce the
-performance impact (on other code) of having KUnit enabled to a single
-NOP when no tests are running.
-
-Note that, while it looks unintuitive, tests always run entirely within
-__kunit_test_suites_init(), so it's safe to decrement the static key at
-the end of this function, rather than in __kunit_test_suites_exit(),
-which is only there to clean up results in debugfs.

-Subject: [PATCH] kunit: Use the static key when retrieving the current
- test
-
-In order to detect if a KUnit test is running, and to access its
-context, the 'kunit_test' member of the current task_struct is used.
-Usually, this is accessed directly or via the kunit_fail_current_task()
-function.
-
-In order to speed up the case where no test is running, add a wrapper,
-kunit_get_current_test(), which uses the static key to fail early.
-Equally, Speed up kunit_fail_current_test() by using the static key.
-
-This should make it convenient for code to call this
-unconditionally in fakes or error paths, without worrying that this will
-slow the code down significantly.
-
-If CONFIG_KUNIT=n (or m), this compiles away to nothing. If
-CONFIG_KUNIT=y, it will compile down to a NOP (on most architectures) if
-no KUnit test is currently running.
-
-Note that kunit_get_current_test() does not work if KUnit is built as a
-module. This mirrors the existing restriction on kunit_fail_current_test().
-
-Note that the definition of kunit_fail_current_test() still wraps an
-empty, inline function if KUnit is not built-in. This is to ensure that
-the printf format string __attribute__ will still work.
-
-Also update the documentation to suggest users use the new
-kunit_get_current_test() function, update the example, and to describe
-the behaviour when KUnit is disabled better.

-Subject: [PATCH] drm/vc4: hvs: Destroy dlist allocations immediately
- when running a test
-
-When running a kunit test, the driver runs with a mock device. As such,
-any attempt to read or write to a hardware register will fail the
-current test immediately.
-
-The dlist allocation management recently introduced will read the
-current frame count from the HVS to defer its destruction until a
-subsequent frame has been output. This obviously involves a register
-read that fails the Kunit tests.
-
-Change the destruction deferral function to destroy the allocation
-immediately if we run under kunit. This is essentially harmless since
-the main reason for that deferall is to prevent any access to the
-hardware dlist while a frame described by that list is rendered. On our
-mock driver, we have neither a hardware dlist nor a rendering, so it
-doesn't matter.

-Subject: [PATCH] ARM: dts: Set the LED default-state to "off"
-
-The default-state property for an LED determines the state of the LED
-when its trigger is set to "none". Many users expect that specifying a
-trigger of "none" means that the LED will be off, and there is a logic
-to that assumption, but the current default of "keep" makes the
-assumption false.
-
-Given that no Pi models have a default-trigger of "none", changing the
-default-state should have no visible impact for most people, but doing
-so will permit a more obvious and more consistent way of turning off
-the LEDs.
-
-Note that 6.2 included an upstream DT reorganisation that required some
-downstream changes, and while doing that I changed the default states.
-This commit brings rpi-6.1.y into line with rpi-6.2.y.
-
-See: https://github.com/raspberrypi/firmware/issues/1742

-Subject: [PATCH] drm/vc4_plane: Add support for YUV444 formats
-
-Support displaying DRM_FORMAT_YUV444 and DRM_FORMAT_YVU444 formats.
-Tested with kmstest and kodi. e.g.
-
-kmstest -r 1920x1080@60 -f 400x300-YU24
-
-Note: without the shift of width, only half the chroma is fetched,
-resulting in correct left half of image and corrupt colours on right half.
-
-The increase in width shouldn't affect fetching of Y data,
-as the hardware will clamp at dest width.

-This aligns vc4 with Intel, AMD and Synopsis drivers and fixes max bpc

-
-max_bpc in connector state is clamped at max_bpc from display info and

-Subject: [PATCH] vc04_services: bcm2835_codec: Ignore READ_ONLY ctrls
- in s_ctrl
-
-In adding the MPEG2/MPEG4/H264 level and profile controls to
-the decoder, they weren't declared as read-only, nor handlers
-added to bcm2835_codec_s_ctrl. That resulted in an error message
-"Invalid control" being logged every time v4l2_ctrl_handler_setup
-was called from bcm2835_codec_create_component.
-
-Define those controls as read only, and exit early from s_ctrl
-on read only controls.
-
-Fixes: "media: bcm2835-v4l2-codec: Add profile & level ctrls to decode"

-
-Historically, downstream Pi DTS files have named the LEDs led0 and (if
-present) led1, while upstream have used the more meaningful "ACT" and
-"PWR". As part of a closer alignment with upstream, make the LED names
-match.

-Restore the ACT LED declaration, but leave it disabled in order to

- value
-
-The datasheet for this sensor documents the minimum vblanking as being
-32 lines. It does fix some problems with occasional black lines at the
-bottom of images (tested on Raspberry Pi).

-Subject: [PATCH] media: i2c: imx219: make HBLANK r/w to allow longer
- exposures
-
-The HBLANK control was read-only, and always configured such
-that the sensor HTS register was 3448. This limited the maximum
-exposure time that could be achieved to around 1.26 secs.
-
-Make HBLANK read/write so that the line time can be extended,
-and thereby allow longer exposures (and slower frame rates).
-Retain the overall HTS setting when changing modes rather than
-resetting it to a default.

-Subject: [PATCH] media: imx219: Advertise embedded data node on media
- pad 1
-
-This commit updates the imx219 driver to adverise support for embedded
-data streams. This can then be used by the bcm2835-unicam driver, which
-has recently been updated to expose the embedded data stream to
-userland.
-
-The imx219 sensor subdevice overloads the media pad to differentiate
-between image stream (pad 0) and embedded data stream (pad 1) when
-performing the v4l2_subdev_pad_ops functions.

-Subject: [PATCH] drm/vc4: drop unnecessary and harmful HDMI RGB format
- check
-
-RGB is a mandatory format for all DVI and HDMI monitors so there's
-no need to check for presence of the DRM_COLOR_FORMAT_RGB444 bit in
-color_formats.
-
-More importantly this checks breaks working around EDID issues with
-eg video=HDMI-A-1:1024x768D or drm.edid_firmware=edid/1024x768.bin
-as the RGB444 bit is only set when a valid EDID with digital bit set in
-the input byte is present - which isn't the case when no EDID can be
-read from the display device at all or with the in-built kernel EDIDs,

-+description: |-
-+ The Sony IMX296 is a 1/2.9-Inch active pixel type CMOS Solid-state image
-+ sensor with square pixel array and 1.58 M effective pixels. This chip
-+ features a global shutter with variable charge-integration time. It is
-+ programmable through I2C and 4-wire interfaces. The sensor output is
-+ available via CSI-2 serial data output (1 Lane).
-+

-+ - sony,imx296lq
-+ description:
-+ The IMX296 sensor exists in two different models, a colour variant
-+ (IMX296LQ) and a monochrome variant (IMX296LL). The device exposes the
-+ model through registers, allowing for auto-detection with a common
-+ "sony,imx296" compatible string. However, some camera modules disable the
-+ ability to read the sensor model register, which disables this feature.
-+ In those cases, the exact model needs to be specified as "sony,imx296ll"
-+ or "sony,imx296lq".

-Subject: [PATCH] media: i2c: IMX296 camera sensor driver
-
-The IMX296LLR is a monochrome 1.60MP CMOS sensor from Sony. The driver
-supports cropping and binning (but not both at the same time due to
-hardware limitations) and exposure, gain, vertical blanking and test
-pattern controls.
-
-Preliminary support is also included for the color IMX296LQR sensor.

- support
-
-Add support for setting horizontal and/or vertial flips in the IMX296
-sensor through the V4L2_CID_HFLIP and V4L2_CID_VFLIP controls.
-
-Add a new helper function to return the media bus format code that
-depends on the sensor flips.
-
-Grab the V4L2_CID_HFLIP and V4L2_CID_VFLIP controls on stream on, and
-release on stream off to ensure flips cannot be changed while the sensor
-is streaming.

-
-Busy spinning after halt is dumb
-We've previously applied this patch to arch/arm
-but it is currenltly missing in arch/arm64
-
-Pi4 after "sudo halt" uses 520mA
-Pi4 after "sudo shutdown now" uses 310mA
-
-Make them both use the lower powered option

- control with long exposure
-
-Setting V4L2_CID_WIDE_DYNAMIC_RANGE was causing the long exposure
-shift count to be reset, which is incorrect if the user has already
-changed the frame length to cause it to have a non-zero value.
-
-Because it only updates control ranges and doesn't set any registers,
-the control can also be applied when the sensor is not powered on.

-Subject: [PATCH] dtoverlays: Add inverted override property to
- ssd1306-spi
-
-The new ssd130x DRM driver supports both SSD1306 I2C and SPI panels and is
-compatible with the ssd1307fb driver bindings. So the "solomon,com-invdir"
-DT property (to invert the COM pin scan dir) can also be used for SPI now.
-
-This allows to configure panels whose scan direction needs to be inverted.

-
-Upstream commit b817888a0c50.
-
-The imx290_write_buffered_reg() function wraps a register write with
-register hold, to enable changing multiple registers synchronously. It
-is used for the gain only, which is an 8-bit register, defeating its
-purpose.
-
-The feature is useful, but should be implemented differently. Drop the
-function for now, to prepare for a rework of register access.

-Subject: [PATCH] media: i2c: imx290: Simplify error handling when
- writing registers
-
-Upstream commit e611f3dac54c.
-
-Error handling for register writes requires checking the error status of
-every single write. This makes the code complex, or incorrect when the
-checks are omitted. Simplify this by passing a pointer to an error code
-to the imx290_write_reg() function, which allows writing multiple
-registers in a row and only checking for errors at the end.
-
-While at it, rename imx290_write_reg() to imx290_write() as there's
-nothing else than registers to write, and rename imx290_read_reg()
-accordingly.

-
-Upstream commit 79d99ae8a77e.
-
-Define macros for all registers programmed by the driver for which
-documentation is available to increase readability. This starts making
-use of 16-bit registers in the register arrays, so the value field has
-to be increased to 32 bits.

-Subject: [PATCH] media: i2c: imx290: Fix max gain value
-
-Upstream commit 6d7a87f2d3a6.
-
-The gain is expressed in multiple of 0.3dB, as a value between 0.0dB
-and 72.0dB. Gains between 0.0dB and 30.0dB (included) apply analog gain
-only, higher gains from 30.3dB to 72dB apply additional digital gain.
-
-The maximum gain value is erroneously set to 72. Increase it to 100 to
-cover the whole analog gain range. Support for digital gain can be added
-separately if needed.
-
-The IMX327 and IMX462 are largely compatible with the IMX290, but have
-an analog gain range of 0.0dB to 29.4dB and 42dB of digital gain. When
-support for those sensors gets added to the driver, the gain control
-should be adjusted accordingly.

-Subject: [PATCH] media: i2c: imx290: Factor out subdev init and
- cleanup to functions
-
-Upstream commit dfb704da8300.
-
-The probe() function is large. Make it more readable by factoring the
-subdev initialization code out. While at it, rename the error labels as
-the "free_" prefix isn't accurate.
-
-No functional change intended.

-
-Avoid accessing the imx290 current_format and current_mode fields in
-imx290_calc_pixel_rate() to prepare for the removal of those fields.
-Among the two callers of the function, imx290_ctrl_update() has an
-explicit mode pointer already, and we can also give it a format pointer.
-Use those explicitly.
-
-While at it, inline the imx290_get_link_freq() function in

- in one place
-
-Upstream commit 693b5cb598cc
-
-The hblank, vblank, pixel rate and link frequency values and limits are
-currently computed when creating controls, in imx290_ctrl_init(), and
-updated in imx290_ctrl_update(). This duplicates the logic in different
-places. Simplify the code by setting the control values and limits to
-hardcoded values when creating the controls, and call

-Subject: [PATCH] media: i2c: imx290: Factor out black level setting to
- a function
-
-Upstream commit ee4ce8936693
-
-The black level programmed in the BLKLEVEL register depends on the
-output format. The black level value computation is currently performed
-in imx290_set_ctrl(), in addition to having different black level values
-in the output-specific register value tables. Move it to a separate
-function to simplify the imx290_set_ctrl() code.

-Subject: [PATCH] media: i2c: imx290: Use V4L2 subdev active state
-
-Upstream commit a2514b9a634a
-
-Use the V4L2 subdev active state API to store the active format. This
-simplifies the driver not only by dropping the imx290 current_format
-field, but it also allows dropping the imx290 lock, replaced with the
-state lock.
-
-The lock check in imx290_ctrl_update() can be dropped as
-imx290_set_fmt() can't be called anywmore with which set to ACTIVE
-before controls are initialized.

-Subject: [PATCH] media: i2c: imx290: Rename, extend and expand usage
- of imx290_pixfmt
-
-Upstream commit 10591fe63691
-
-The imx290_pixfmt structure contains information about formats,
-currently limited to the bpp value. Extend it with the register settings
-for each format, and rename it to imx290_format_info to make its purpose
-clearer. Add a function named imx290_format_info() to look up format
-info for a media bus code, and use it through the code. This allows
-dropping the imx290 bpp field as the value is now looked up dynamically.
-
-The error handling in imx290_setup_format() can also be dropped, as the
-format is guaranteed by imx290_set_fmt() to be valid.

-
-Upstream commit a8c3e0c1bf1e
-
-Use runtime PM autosuspend to avoid powering off the sensor during fast
-stop-reconfigure-restart cycles. This also fixes runtime PM handling in
-the probe function that didn't suspend the device, effectively leaving
-it resumed forever.
-
-While at it, improve documentation of power management in probe() and
-remove().

-Subject: [PATCH] media: i2c: imx290: Initialize runtime PM before
- subdev
-
-Upstream commit 02852c01f654
-
-Initializing the subdev before runtime PM means that no subdev
-initialization can interact with the runtime PM framework. This can be
-problematic when modifying controls, as the .s_ctrl() handler commonly
-calls pm_runtime_get_if_in_use(). These code paths are not trivial,
-making the driver fragile and possibly causing subtle bugs.
-
-To make the subdev initialization more robust, initialize runtime PM
-first.

-volunteering myself.
-
-The name of the input clock, "xclk", is wrong as the hardware manual

-Subject: [PATCH] media: i2c: imx290: Fix the pixel rate at 148.5Mpix/s
-
-Should be upstream commit 4381df0c756f
-
-The datasheet lists the link frequency changes between
-1080p and 720p modes. This is correct that the link frequency
-changes as measured on an oscilloscope.
-
-Link frequency is not necessarily the same as pixel rate.
-
-The datasheet gives standard configurations for 1080p and 720p
-modes at a number of frame rates.
-Looking at the 1080p mode it gives:
-HMAX = 0x898 = 2200
-VMAX = 0x465 = 1125
-2200 * 1125 * 60fps = 148.5MPix/s
-
-Looking at the 720p mode it gives:
-HMAX = 0xce4 = 3300
-VMAX = 0x2ee = 750
-3300 * 750 * 60fps = 148.5Mpix/s
-
-This driver currently scales the pixel rate proportionally to the
-link frequency, however the above shows that this is not the
-correct thing to do, and currently all frame rate and exposure
-calculations give incorrect results.
-
-Correctly report the pixel rate as being 148.5MPix/s under any
-mode.

-
-Should be upstream commit 7d4f22ba99cc
-
-Commit "97589ad61c73 media: i2c: imx290: Add support for 2 data lanes"
-added support for running in two lane mode (instead of 4), but
-without changing the link frequency that resulted in a max of 30fps.
-
-Commit "98e0500eadb7 media: i2c: imx290: Add configurable link frequency
-and pixel rate" then doubled the link frequency when in 2 lane mode,
-but didn't undo the correction for running at only 30fps, just extending
-horizontal blanking instead.
-
-Remove the 30fps limit on 2 lane by correcting the register config
-in accordance with the datasheet for 60fps operation over 2 lanes.

-
-Should be upstream commit b3aa351ea88a
-
-The default VMAX for 60fps in 720p mode is 750 according to the
-datasheet, however the driver always left it at 1125 thereby stopping
-60fps being achieved.
-
-Make VMAX (and therefore V4L2_CID_VBLANK) mode dependent so that 720p60
-can be achieved.

-
-Should be upstream commit 42765b80f8c6
-
-The sensor supports H & V flips, so add the relevant hooks for
-V4L2_CID_HFLIP and V4L2_CID_VFLIP to configure them.
-
-Note that the Bayer order is maintained as the readout area
-shifts by 1 pixel in the appropriate direction (note the
-comment about the top margin being 8 pixels whilst the bottom
-margin is 9). The V4L2_SEL_TGT_CROP region is therefore
-adjusted appropriately.

-Subject: [PATCH] fbdev: Don't cancel deferred work if pagelist empty
-
-Since [1], the fbdev deferred IO framework is careful to cancel
-pending updates on close to prevent dirty pages being accessed after
-they may have been reused. However, this is not necessary in the case
-that the pagelist is empty, and drivers that don't make use of the
-pagelist may have wanted updates cancelled for no good reason.
-
-Avoid penalising fbdev drivers that don't make use of the pagelist by
-making the cancelling of deferred IO on close conditional on there
-being a non-empty pagelist.

-frequency is handled thorugh the "link-frequency" overlay parameter.

- with same node
-
-media_pipeline_start and media_pipeline_stop now validate that
-the pipeline is being started and stopped with the same pipe
-and pad handles.
-When running with embedded metadata (eg imx477 and imx708), the
-start typically happens from the metadata pad, whilst stop is
-always from the image pad.
-
-Always pass the image pad to media_pipeline_start to ensure
-that the calls are balanced.

-
-There is an off-by-one error in the default brightness for the PWM backlight
-in the MIPI DBI SPI overlay that produces the following message in the
-kernel logs:
-
- pwm-backlight backlight_pwm: invalid default brightness level: 16, using 15
-
-The value is 0-based, so the max brightness is 15, not 16.

- pwm-max to u8
-
-There is no DT binding for emc2305 as mainline are still
-discussing how to do a generic fan binding.
-The 5.15 driver was reading the "emc2305," properties
-"cooling-levels", "pwm-max", "pwm-min", and "pwm-channel" as u8.
-The overlay was writing them as u16 (;) so it was working.
-
-The 6.1 driver was reading as u32, which failed as there is
-insufficient data.
-
-As this is all downstream only, revert to u8 to match 5.15.

-Subject: [PATCH] serial: 8250: Add NOMSI bug for bcm2835aux
-
-The BCM2835 mini-UART has no modem status interrupt, causing all
-transmission to stop, never to use, if a speed change ever happens
-while the CTS signal is high.
-
-Add a simple polling mechanism in order to allow recovery in that
-situation.

-Subject: [PATCH] pinctrl: bcm2835: Workaround for edge IRQ loss
-
-It has been observed that edge events can be lost when GPIO edges occur
-close to each other. Investigation suggests this is due to a hardware
-bug, although no mechanism has been identified.
-
-Work around the event loss by moving the IRQ acknowledgement into the
-main ISR, adding missing events by explicit level-change detection.

-Subject: [PATCH] drm/v3d: New debugfs end-points to query GPU usage
- stats.
-
-Two new debugfs interfaces are implemented:
-
-- gpu_usage: exposes the total runtime since boot of each
-of the 5 scheduling queues available at V3D (BIN, RENDER,
-CSD, TFU, CACHE_CLEAN). So if the interface is queried at
-two different points of time the usage percentage of each
-of the queues can be calculated.
-
-- gpu_pid_usage: exposes the same information but to the
-level of detail of each process using the V3D driver. The
-runtime for process using the driver is stored. So the
-percentages of usage by PID can be calculated with
-measures at different timestamps.
-
-The storage of gpu_pid_usage stats is only done if
-the debugfs interface is polled during the last 70 seconds.
-If a process does not submit a GPU job during last 70
-seconds its stats will also be purged.

-Subject: [PATCH] bcm2835-dma: Derive slave DMA addresses correctly
-
-Slave addresses for DMA are meant to be supplied as physical addresses
-(contrary to what struct snd_dmaengine_dai_dma_data does). It is up to
-the DMA controller driver to perform the translation based on its own
-view of the world, as described in Device Tree.
-
-Now that the Pi Device Trees have the correct peripheral mappings,
-replace the hacky address munging with phys_to_dma().

-
-The bcm2835_dma_create_cb_chain() function is in charge of building up
-the descriptors chain for a given transfer.
-
-It was initially supporting only the BCM2835-style DMA controller, and
-was later expanded to support controllers with 40-bits channels that use
-a different descriptor layout.
-
-However, some part of the function only use the old style descriptor,
-even when building a chain of new-style descriptors, resulting in weird
-bugs.

-
-The sequence we were doing was not safe.
-
-Clearing CS meant BCM2835_DMA_WAIT_FOR_WRITES was cleared
-and so polling BCM2835_DMA_WAITING_FOR_WRITES has no benefit
-
-Broadcom have provided a recommended sequence to abort
-a dma lite channel, so switch to that.

-Subject: [PATCH] bcm2711-rpi-ds: Switch to dma40 channel for hdmi
- audio
-
-Also tweak the flags:
-Remove NO_WAIT_RESP (27)
-Add BURST_LENGTH (30)
-
-The AXI path from DMA controller to HDMI audio fifo
-is long, and may have considerable delay.
-
-When using DMA without waiting for responses it is
-very easy to overfill the fifo as when the fifo
-removes DREQ there may be large numbers of writes
-in flight.
-
-This means the DREQ fifo threshold must be set low
-enough to accommodate the maximum number of in flight
-writes (unknown by something like 24),
-which means the 32 element fifo only requests data
-when it contains fewer than 8 entries, making it
-susceptable to underflow.
-
-If we wait for write responses we can set the DREQ
-fifo threshold much higher as there are a controlled
-number of writes in flight.
-
-However the overall bandwidth is reduced by setting
-this, so also enable a burstsize of 4 to improve
-bandwidth.

-Subject: [PATCH] ARM: dts: bcm2711-rpi: Set a 1GB ZONE_DMA limit
-
-The arm64 initialisation uses the physical address reachable by all
-DMA controllers to set the size of ZONE_DMA. This fails on BCM2711
-with the current dts files because the declaration of the I/O space
-fools it into thinking the legacy 30-bit DMA channels can see most
-of the 32-bit space.
-
-Take advantage of the simple nature of the implementation by adding
-a node with a restricted dma-ranges property solely so to act as the
-limiting factor in the calculation.

-Subject: [PATCH] ARM: dts: bcm27xx: Add stdout-path to serial0
-
-Rather than deleting the upstream stdout-path declaration, overwrite
-it with one selecting serial0, which will always be the UART mapped
-to the 40-pin header (provided enable_uart=1 is specified). Doing
-so has the advantage that earlycon can be configured just by adding
-"earlycon" to the command line.

-Subject: [PATCH] input: edt-ft5x06: Only read data for number of
- points reported
-
-Rather than always reading the maximum number of points supported
-by the chip (which may be as high as 10), read the number of
-active points first, and read data for just those.
-In most cases this will result in less data on the I2C bus,
-with only the maximum touch points taking more due to a second
-read that has to configure the start address.

-Subject: [PATCH] pps: Compatibility hack should be X86-specific
-
-As of [1], using PPS_FETCH on a 64-bit ARM kernel with a 32-bit userland
-is broken, returning a timeout. This is because the requested 4-byte
-alignment for struct pps_ktime_compat (illegal on arm64) results in the
-timeout flags field being uninitialised.
-
-Make the hack specific to X86_64 builds with CONFIG_COMPAT defined.

-Subject: [PATCH] bcm2835-dma: Fixes for dma_abort
-
-There is a problem with the current abort scheme
-when dma is blocked on a DREQ which prevents halting.
-
-This is triggered by SPI driver which aborts dma
-in this state and so leads to a halt timeout.
-
-Discussion with Broadcom suggests the sequence:
-
-CS.ACTIVE=0
-while (CS.OUTSTANDING_TRANSACTIONS == 0)
- wait()
-DEBUG.RESET=1
-
-should be safe on a dma40 channel.
-
-Unfortunately the non-dma40 channels don't have
-OUTSTANDING_TRANSACTIONS, so we need a more
-complicated scheme.
-
-We attempt to abort the channel, which will work
-if there is no blocked DREQ.
-
-It it times out, we can assume there is no AXI
-transfer in progress and reset anyway.
-
-The length of the timeout is observed at ~20us.

-Subject: [PATCH] panel-sitronix-st7701: Fix panel prepare over SPI
-
-A DSI write is issued in st7701_prepare even when the probed panel
-runs on SPI. In practice, this results in a panic with the
-vc4-kms-dpi-hyperpixel2r overlay active.
-
-Perform the equivalent write over SPI in this case.

-Subject: [PATCH] media: i2c: imx219: fix binning and rate_factor for 480p and
- 1232p
-
-At a high FPS with RAW10, there is frame corruption for 480p because the
-rate_factor of 2 is used with the normal 2x2 bining [1]. This commit
-ties the rate_factor to the selected binning mode. For the 480p mode,
-analog 2x2 binning mode with a rate_factor of 2 is always used. For the
-1232p mode the normal 2x2 binning mode is used for RAW10 while analog
-2x2 binning mode is used for RAW8.

-Subject: [PATCH] ALSA: pcm: fix ELD constraints for (E)AC3, DTS(-HD) and MLP
- formats
-
-commit 04b49b90caeed0b5544ff616d654900d27d403b6 upstream.
-
-The SADs of compressed formats contain the channel and sample rate
-info of the audio data inside the compressed stream, but when
-building constraints we must use the rates and channels used to
-transport the compressed streams.
-
-eg 48kHz 6ch EAC3 needs to be transmitted as a 2ch 192kHz stream.
-
-This patch fixes the constraints for the common AC3 and DTS formats,
-the constraints for the less common MPEG, DSD etc formats are copied
-directly from the info in the SADs as before as I don't have the specs
-and equipment to test those.

-Subject: [PATCH] ASoC: hdmi-codec: fix channel info for compressed formats
-
-commit 4e0871333661d2ec0ed3dc00a945c2160eccae77 upstream.
-
-According to CTA 861 the channel/speaker allocation info in the
-audio infoframe only applies to uncompressed (PCM) audio streams.
-
-The channel count info should indicate the number of channels
-in the transmitted audio, which usually won't match the number of
-channels used to transmit the compressed bitstream.
-
-Some devices (eg some Sony TVs) will refuse to decode compressed
-audio if these values are not set correctly.
-
-To fix this we can simply set the channel count to 0 (which means
-"refer to stream header") and set the channel/speaker allocation to 0
-as well (which would mean stereo FL/FR for PCM, a safe value all sinks
-will support) when transmitting compressed audio.

-Subject: [PATCH] media: i2c: arducam_64mp: Modify the line length of 1280x720
- resolution
-
-Arducam 64MP has specific requirements for the line length, and if these
-conditions are not met, the camera will not function properly. Under the
-previous configuration, once a stream off operation is performed, the
-camera will not output any data, even if a stream on operation is
-performed. This prevents us from switching from 1280x720 to another
-resolution.

-usbnet: smsc95xx: Simplify MAC address parsing
-
-Parsing the MAC address provided on the kernel command line can be
-simplified quite a bit by taking advantage of the kernel's built-in
-mac_pton() helper.
-
-Likewise emitting the MAC address can be simplified with the %pM
-format string conversion.

-
-The Raspberry Pi Codec Zero (and IQaudIO Codec) don't notify the DA7213
-codec when it needs to change PLL frequencies. As a result, audio can
-be played at the wrong rate - play a 48kHz sound immediately after a
-44.1kHz sound to see the effect, but in some configurations the codec
-can lock into the wrong state and always get some rates wrong.
-
-Add the necessary notification to fix the issue.

-Subject: [PATCH] can: isotp: add module parameter for maximum pdu size
-
-commit 96d1c81e6a0478535342dff6c730adb076cd84e8 upstream.
-
-With ISO 15765-2:2016 the PDU size is not limited to 2^12 - 1 (4095)
-bytes but can be represented as a 32 bit unsigned integer value which
-allows 2^32 - 1 bytes (~4GB). The use-cases like automotive unified
-diagnostic services (UDS) and flashing of ECUs still use the small
-static buffers which are provided at socket creation time.
-
-When a use-case requires to transfer PDUs up to 1025 kByte the maximum
-PDU size can now be extended by setting the module parameter
-max_pdu_size. The extended size buffers are only allocated on a
-per-socket/connection base when needed at run-time.
-
-changes since v2: https://lore.kernel.org/all/20230313172510.3851-1-socketcan@hartkopp.net
-- use ARRAY_SIZE() to reference DEFAULT_MAX_PDU_SIZE only at one place
-
-changes since v1: https://lore.kernel.org/all/20230311143446.3183-1-socketcan@hartkopp.net
-- limit the minimum 'max_pdu_size' to 4095 to maintain the classic
- behavior before ISO 15765-2:2016

-Subject: [PATCH] drivers: irqchip: irq-bcm2835: Concurrency fix
-
-The commit shown in Fixes: aims to improve interrupt throughput by
-getting the handlers invoked on different CPU cores. It does so (*) by
-using an irq_ack hook to change the interrupt routing.
-
-Unfortunately, the IRQ status bits must be cleared at source, which only
-happens once the interrupt handler has run - there is no easy way for
-one core to claim one of the IRQs before sending the remainder to the
-next core on the list, so waking another core immediately results in a
-race with a chance of both cores handling the same IRQ. It is probably
-for this reason that the routing change is deferred to irq_ack, but that
-doesn't guarantee no clashes - after irq_ack is called, control returns
-to bcm2836_chained_handler_irq which proceeds to check for other pending
-IRQs at a time when the next core is probably doing the same thing.
-
-Since the whole point of the original commit is to distribute the IRQ
-handling, there is no reason to attempt to handle multiple IRQs in one
-interrupt callback, so the problem can be solved (or at least made much
-harder to reproduce) by changing a "while" into an "if", so that each
-invocation only handles one IRQ.
-
-(*) I'm not convinced it's as effective as claimed since irq_ack is
-called _after_ the interrupt handler, but the author thought it made a
-difference.
-
-See: https://github.com/raspberrypi/linux/issues/5214
- https://github.com/raspberrypi/linux/pull/1794
-
-Fixes: fd4c9785bde8 ("ARM64: Round-Robin dispatch IRQs between CPUs.")

-Subject: [PATCH] drm/ili9486: Resolve clash in spi_device_id names
-
-For "Really Good Reasons" [1] the SPI core requires a match
-between compatible device strings and the name in spi_device_id.
-
-The ili9486 driver uses compatible strings "waveshare,rpi-lcd-35"
-and "ozzmaker,piscreen", but "rpi-lcd-35" and "piscreen" are missing,
-so add them.
-
-Compatible string "ilitek,ili9486" is already used by
-staging/fbtft/fb_ili9486, therefore leaving it present in ili9486 as an
-spi_device_id causes the incorrect module to be loaded, therefore remove
-this id.

-Subject: [PATCH] f2fs: fix to avoid NULL pointer dereference in
- f2fs_issue_flush()
-
-commit b3d83066cbebc76dbac8a5fca931f64b4c6fff34 upstream.
-
-With below two cases, it will cause NULL pointer dereference when
-accessing SM_I(sbi)->fcc_info in f2fs_issue_flush().
-
-a) If kthread_run() fails in f2fs_create_flush_cmd_control(), it will
-release SM_I(sbi)->fcc_info,
-
-- mount -o noflush_merge /dev/vda /mnt/f2fs
-- mount -o remount,flush_merge /dev/vda /mnt/f2fs -- kthread_run() fails
-- dd if=/dev/zero of=/mnt/f2fs/file bs=4k count=1 conv=fsync
-
-b) we will never allocate memory for SM_I(sbi)->fcc_info w/ below
-testcase,
-
-- mount -o ro /dev/vda /mnt/f2fs
-- mount -o rw,remount /dev/vda /mnt/f2fs
-- dd if=/dev/zero of=/mnt/f2fs/file bs=4k count=1 conv=fsync
-
-In order to fix this issue, let change as below:
-- fix error path handling in f2fs_create_flush_cmd_control().
-- allocate SM_I(sbi)->fcc_info even if readonly is on.

-Subject: [PATCH] overlays: Add a sample hat_map
-
-The HAT map is way of associating named overlays with HATs whose
-EEPROMs were programmed with the contents of the overlay.
-Unfortunately, change in the DT and kernel drivers has meant that some
-of these embedded overlays no longer function, or even don't apply.
-
-The HAT map is a mapping from HAT UUIDs to overlay names. If a HAT with
-a listed UUID is detected, the embedded overlay is ignored and the
-overlay named in the mapping is loaded in its place.

-Subject: [PATCH] gpio_brcmstb: Allow to build for ARCH_BCM2835
-
-gpio-brcmstb: Report the correct bank width
-
-gpio: brcmstb: Use bank address as gpiochip label
-
-If the path to the device node is used as gpiochip label then
-gpio-brcmstb instances with multiple banks end up with duplicated
-names. Instead, use a combination of the driver name with the physical
-address of the bank, which is both unique and helpful for devmem
-debugging.

-
-gpio: mmio: Add DIRECT mode for shared access
-
-The generic MMIO GPIO library uses shadow registers for efficiency,
-but this breaks attempts by raspi-gpio to change other GPIOs in the
-same bank. Add a DIRECT mode that makes fewer assumptions about the
-existing register contents, but note that genuinely simultaneous
-accesses are likely to lose updates.
-
-Signed-off-by: Phil Elwell <phil@raspberrypi.com>
-
-gpio: brcmstb: Don't always clear interrupt mask
-
-If the GPIO controller is not being used as an interrupt source
-leave the interrupt mask register alone. On BCM2712 it might be used
-to generate interrupts to the VPU firmware, and on other devices it
-doesn't matter since no interrupts will be generated.

-Subject: [PATCH] mmc: brcmstb: add support for BCM2712
-
-BCM2712 has an SD Express capable SDHCI implementation and uses
-the SDIO CFG register block present on other STB chips.
-
-Add plumbing for SD Express handover and BCM2712-specific functions.
-
-Due to the common bus infrastructure between BCM2711 and BCM2712,
-the driver also needs to implement 32-bit IO accessors.
-
-mmc: brcmstb: override card presence if broken-cd is set
-
-Not just if the card is declared as nonremovable.
-
-sdhci: brcmstb: align SD express switchover with SD spec v8.00
-
-Part 1 of the Physical specification, figure 3-24, details the switch
-sequence for cards initially probed as SD. Add a missing check for DAT2
-level after switching VDD2 on.
-
-sdhci: brcmstb: clean up SD Express probe and error handling
-
-Refactor to avoid spurious error messages in dmesg if the requisite SD
-Express DT nodes aren't present.
-
-Signed-off-by: Jonathan Bell <jonathan@raspberrypi.com>
-
-mmc: sdhci-brcmstb: only use the delay line PHY for tuneable speeds
-
-The MMC core has a 200MHz core clock which allows the use of DDR50 and
-below without incremental phase tuning. SDR50/SDR104 and the EMMC HS200
-speeds require tuning.

-
-To support 2 concurrent libcamera applications, we need 2 node groups,
-need to allow multiple opens of each node (because libcamera does this)
-and create a separate media device per group (to support file-locking).
-
-This triggered significant rearrangement of the driver. Some calls

-Logging changes arising from multiple v4l2_dev. Refactored probe()
-and initialization. Avoid dynamically-allocated entity name strings.

-media: bcm2712: Fix v4l2-compliance warn on invalid pixfmt
-
-The V4L2 API for the TRY_FMT/S_FMT ioctl allows the ioctl handler to
-return an error code only in specific conditions. If an invalid pixel
-format is supplied it should be adjusted instead of an error being
-returned.
-
-Albeit, v4l2-compliance treats this situation as a warning and not as
-an error because the behaviour has been discussed in length in the past.
-
-warn: v4l2-test-formats.cpp(794): TRY_FMT cannot handle an invalid pixelformat.
-warn: v4l2-test-formats.cpp(795): This may or may not be a problem. For more information see:
-warn: v4l2-test-formats.cpp(796): http://www.mail-archive.com/linux-media@vger.kernel.org/msg56550.html
-VIDIOC_TRY_FMT returned -1 (Invalid argument)
-
-Regardless of the warning vs failure decision, adjust the try_format()
-function implementation to use V4L2_PIX_FMT_YUV420M as default pixel
-format if the supplied one is invalid.

-media: bcm2712: Fix v4l2-compliance warn on HOG pix format
-
-The try_format() implementation for the HOG video device node returns
-an error if the supplied pixel format is not correct.
-
-As per the video device output and capture video nodes, this contradicts
-the V4L2 specification even if it is treated as a warning by
-v4l2-compliance.
-
-Fix this by forcing the buffer pixel format and size to the default
-supported one. While at here, use the BIT() macro in the format
-initialization function.

-
-media: bcm2712: Fix formats enumeration
-
-Right now a single implementation of enum_fmt() is used for all nodes
-in a group. This means that all the BE supported formats are listed for
-all the nodes. This is incorrect as the meta capture and output node
-formats should be restricted, and the meta formats should not be
-enumerated for video output and capture devices.
-
-Fix this by restricting the enumeration of META formats to the config
-and hog nodes. Split out from the list of supported_formats the
-V4L2_META_FMT_RPI_BE_CFG which is only used for the meta_out node, while
-V4L2_PIX_FMT_RPI_BE is kept in the list of supported_formats as it can
-be used as an opaque format for both meta_cap, video_cap and video_out
-nodes.

-irqchip: bcm2712-mip: add a quick hack to optionally shift MSI vectors
-
-There are two MIP peripherals in bcm2712, the first gets a first-class
-treatment where 64 consecutive GIC SPIs are assigned to all 64 output
-vectors. The second gets an agglomeration of 17 GIC SPIs, but only 8 of
-these are consecutive starting at the 8th output vector.
-
-For now, allow the use of this smaller contiguous range within a larger
-whole.

-
-Increase polling interval for MDIO completion
-
-MDIO is a slow bus (single-digit MHz). Polling at 1us intervals
-is a bit aggressive, so increase to 100us as the transaction
-usually takes 100-200us to complete.

-net: macb: add hack to prevent TX stalls in a quiet system
-
-See https://github.com/raspberrypi/linux-2712/issues/89
-
-There is some critical window during TX where a further write to the
-TSTART bit while TX is active does not cause newly queued TX descriptors
-to be consumed.
-
-For now "wait a bit, then try anyway" seems to work.
-
-Requires further investigation, but this unsticks NFS reliably.

-net: macb: set default interrupt moderation for GEM hardware
-
-Defaulting to intmod = 0 is antisocial, as the MAC can generate over
-130,000 interrupts per second. 50us is a sensible default.

-Subject: [PATCH] usb: dwc3: Set DMA and coherent masks early
-
-dwc3 allocates scratch and event buffers in the top-level driver. Hack the
-probe function to set the DMA mask before trying to allocate these.
-
-I think the event buffers are only used in device mode, but the scratch
-buffers may be used if core hibernation is enabled.
-
-usb: dwc3: add support for new DT quirks
-
-Apply the optional axi-pipe-limit and dis-in-autoretry-quirk properties
-during driver probe.

-
-If two instances of a dwc3 host controller are specified in devicetree,
-then the probe order may be arbitrary which results in the device names
-swapping on a per-boot basis.
-
-If a "usb" alias with the instance number is specified, then use
-that to construct the device name instead of autogenerating one.

-Subject: [PATCH] PCI: brcmstb: Add BCM2712 support
-
-PCI: brcmstb: differing register offsets on 2712
-
-pcie-brcmstb: Add 2712 bridge reset support
-
-pcie: 2712 PORT_MASK and rescal support
-
-pcie-brcmstb: don't alter the L1SS debug register
-
-For reasons unknown, this disables the reference clock
-
-pcie-brcmstb: fix BAR2 enable and window decode
-
-Set UBUS ACCESS_EN to let inbound DMA work. Also BCM2712 has grown
-an index in the inbound window size decode register.
-
-PCIe: brcmstb: Enable support for 64 MSI-Xs
-
-Signed-off-by: Phil Elwell <phil@raspberrypi.com>
-
-pcie-brcmstb: Suppress read error responses
-
-If the link is down or the EP fails to return a read completion, the
-RC's default behaviour is to return an AXI error. This causes fatal
-exceptions on A76, so it's better to respond with all 1s instead.
-
-pcie-brcmstb: increase UBUS timeout to cater for link retrain events
-
-pcie-brcmstb: Handle additional inbound regions
-
-Signed-off-by: Phil Elwell <phil@raspberrypi.com>
-
-pcie-brcmstb: Add support for external MSI controller
-
-pcie-brcmstb: add a reasonable default traffic class to priority map
-
-BCM2712 supports multiple traffic classes (TCs) with independent
-maximally sized transfer queues for each TC. Traffic classes have no
-transaction ordering requirements between them, which facilitates
-out-of-order completions and arbitration between posted writes for
-data streams that have no dependence on each other.
-
-In addition to the above benefits of splitting endpoint traffic into
-individual queues, priorities can be assigned to traffic classes by
-a heuristic or deterministic mechanism. The heuristic elevates AXI
-QOS priority in accordance with the number of pending transfers in
-each TC's queue, but for true priority signalling a forwarding
-mechanism using vendor-defined messages is implemented.
-
-Receipt of a 3 DWORD VDM assigns a priority tag to a TC on-the-fly,
-and this tag corresponds to a configurable AXI QOS value.
-
-As a simple baseline, assign a linear map of AXI QOS to each tag.
-
-pcie: brcmstb: set up the VDM forwarding interface when setting up QoS
-
-pcie-brcmstb: add DT bindings for MPS-size Read Completion Mode
-
-This controller has an optional feature that allows read completion
-TLPs to be sized up to the Maximum Packet Size of a configured link.
-
-This can exceed the Read Completion Boundary of 128B specified in
-the PCIe specification, but depending on endpoint support may increase
-link read bandwidth significantly.
-
-pcie-brcmstb: clean up debug messages
-
-pcie-brcmstb: fix BCM2712A0 PHY PM errata
-
-The power management clock is 54MHz not 50MHz, so adjust the PM clock period
-to suit. Powering off the PHY PLL in L1.2 is unsafe, so force it on.
-
-pcie-brcmstb: set CLKREQ functionality according to link partner support
-
-The RC supports either L1 with clock PM or L1 sub-state control, not both
-at the same time. Examine the link partner's capabilities to determine
-which is the most suitable scheme to use.
-
-pcie: brcmstb: don't reset block bridges in suspend or removal cases
-
-BCM2712 has a single rescal block for all three root complexes, and
-holding PCIE1's bridge in reset will hang the chip if a different
-RC wants to access any of the rescal registers.
-
-pcie: brcmstb: guard 2712-specific setup with a RC type check
-
-BCM2711 doesn't implement the UBUS control registers.
-
-pcie: brcmstb: On 2712 keeping the PLL powered in L1.x is not required
-
-A separate misconfiguration when enabling SSC (the MDIO registers no
-longer do the same thing on BCM2712) had the side-effect of breaking
-PLL powerdown and resume sequencing.
-
-Allow entry into a true L1.2 state where analogue is depowered.
-
-pcie: brcmstb: Fix reset warning on probe failure
-
-Signed-off-by: Phil Elwell <phil@raspberrypi.com>
-
-bcm2712: pcie: adjust PHY PLL setup to use a 54MHz input refclk
-
-Use canned MDIO writes from Broadcom that switch the ref_clk output
-pair to run from the internal fractional PLL, and set the internal PLL
-to expect a 54MHz input reference clock.
-
-Gen3 operation is not guaranteed to be stable in this setup, so default
-to gen2.
-
-This only works if the LCPLL is bypassed (requires latest bootloader).
-
-pcie: brcmstb: add missing register writes
-
-drivers: pcie: brcmstb: cater for BCM2712C0 bug dropping QoS on the floor
-
-The AXI QoS value extracted from the request fifo ends up as zero forever.
-Disabling this means that "panic" signalling doesn't do anything useful,
-but static priorites do work.
-
-Also align the selected TC:QoS map with RP1's expectations of service.
-
-Signed-off-by: Jonathan Bell <jonathan@raspberrypi.com>
-
-drivers: pcie: brcmstb: shuffle TC priorities up to 8
-
-Use the range 8-11 which puts the highest below HVS but leaves space
-below for other 2712 masters.
-
-Signed-off-by: Jonathan Bell <jonathan@raspberrypi.com>
-
-drivers: pcie: brcmstb: optionally enable QoS features by DT for BCM2712
-
-It's a bad idea to universally enable "realtime" priorities for TCs
-across all the RC instances on the chip. Endpoints other than RP1 may
-make use of these, so you don't want e.g. NVMe descriptor fetches getting
-higher priority than your remote display.
-
-Add two optional DT properties controlling the behaviour - FIFO-based
-backpressure QoS or "message-based". Message-based signalling is
-fundamentally broken due to a chip bug, so it collapses into a set of
-static assignments that RP1 needs.
-
-The default if neither property is specified is to assign everything a
-QoS of 0.
-
-Signed-off-by: Jonathan Bell <jonathan@raspberrypi.com>
-
-drivers: pcie: brcmstb: adjust completion timeouts for bcm2712
-
-Setting the RC config retry timeout makes CRS auto-polling work, but
-the UBUS timeout will override the config retry. Both need to be large.

-Subject: [PATCH] i2c: designware: Add SMBUS quick command support
-
-The SMBUS emulation code turns an SMBUS quick command into a zero-
-length read. This controller can't do zero length accesses, but it
-can do quick commands, so reverse the emulation. The alternative
-would be to properly implement the SMBUS support but that is a lot
-more work, and unnecessary just to get i2cdetect working.

-Subject: [PATCH] dmaengine: dw-axi-dmac: Fixes for RP1
-
-Don't assume that DMA addresses of devices are the same as their
-physical addresses - convert correctly.
-
-The CFG2 register layout is used when there are more than 8 channels,
-but also when configured for more than 16 target peripheral devices
-because the index of the handshake signal has to be made wider.
-
-Reset the DMAC on probe
-
-The driver goes to the trouble of tracking when transfers have been
-paused, but then doesn't report that state when queried.
-
-Not having APB registers is not an error - for most use cases it's
-not even of interest, it's expected. Demote the message to debug level,
-which is disabled by default.
-
-Each channel has a descriptor pool, which is shared between transfers.
-It is unsafe to treat the total number of descriptors allocated from a
-pool as the number allocated to a specific transfer; doing so leads
-to releasing buffers that shouldn't be released and walking off the
-ends of descriptor lists. Instead, give each transfer descriptor its
-own count.
-
-Support partial transfers:
-Some use cases involve streaming from a device where the transfer only
-proceeds when the device's FIFO occupancy exceeds a certain threshold.
-In such cases (e.g. when pulling data from a UART) it is important to
-know how much data has been transferred so far, in order that remaining
-bytes can be read from the FIFO directly by software.
-
-Add the necessary code to provide this "residue" value with a finer,
-sub-transfer granularity.
-
-In order to prevent the occasional byte getting stuck in the DMA
-controller's internal buffers, restrict the destination memory width
-to the source register width.

-Subject: [PATCH] ASOC: dwc: Fix 16-bit audio handling
-
-IMO the Synopsys datasheet could be clearer in this area, but it seems
-that the DMA data ports (DMATX and DMARX) expect left and right samples
-in alternate writes; if a stereo pair is pushed in a single 32-bit
-write, the upper half is ignored, leading to double speed audio with a
-confused stereo image. Make sure the necessary changes happen by
-updating the DMA configuration data in the hw_params method.
-
-The set_bclk_ratio change was made at a time when it looked like it
-could be causing an error, but I think the division of responsibilities
-is clearer this way (and the kernel log clearer without the info-level
-message).

-Subject: [PATCH] drivers: char: add generic gpiomem driver
-
-Based on bcm2835-gpiomem.
-
-We allow export of the "GPIO registers" to userspace via a chardev as
-this allows for finer access control (e.g. users must be group gpio, root
-not required).
-
-This driver allows access to either rp1-gpiomem or gpiomem, depending on
-which nodes are populated in devicetree.
-
-RP1 has a different look-and-feel to BCM283x SoCs as it has split ranges
-for IO controls and the parallel registered OE/IN/OUT access. To handle
-this, the driver concatenates the ranges for an IO bank and the
-corresponding RIO instance into a contiguous buffer.

-Subject: [PATCH] drivers: iommu: Add BCM2712 IOMMU
-
-Add a driver for BCM2712 IOMMUs.
-There is a small driver for the Shared IOMMU TLB Cache.
-Each IOMMU instance is a separate device.
-
-IOMMUs are set up with a "pass-through" range covering
-the lowest 40BGytes (which should cover all of SDRAM)
-for the benefit of non-IOMMU-aware devices that share
-a physical IOMMU; and translation for addresses in the
-range 40GB to 42GB.
-
-An optional parameter adds a DMA offset (which otherwise
-would be lost?) to virtual addresses for DMA masters on a
-bus such as PCIe.

-Subject: [PATCH] irqchip/irq-brcmstb-l2: Add config for 2711 controller
-
-We currently see these regularly:
-[ 25.157560] irq 31, desc: 00000000c15e6d2c, depth: 0, count: 0, unhandled: 0
-[ 25.164658] ->handle_irq(): 00000000b1775675, brcmstb_l2_intc_irq_handle+0x0/0x1a8
-[ 25.172352] ->irq_data.chip(): 00000000fea59f1c, gic_chip_mode1+0x0/0x108
-[ 25.179166] ->action(): 000000003eda6d6f
-[ 25.183096] ->action->handler(): 000000002c09e646, bad_chained_irq+0x0/0x58
-[ 25.190084] IRQ_LEVEL set
-[ 25.193142] IRQ_NOPROBE set
-[ 25.196198] IRQ_NOREQUEST set
-[ 25.199255] IRQ_NOTHREAD set
-
-with:
-$ cat /proc/interrupts | grep 31:
- 31: 1 0 0 0 GICv2 129 Level (null)
-
-The interrupt is described in DT with IRQ_TYPE_LEVEL_HIGH
-
-But the current compatible string uses the controller in edge triggered mode
-(as that config matches our register layout).
-
-Add a new compatible structure for level driven interrupt with our register layout.
-
-We had already been using this compatible string in device tree, so no change needed
-there.

-Subject: [PATCH] rtc: rtc-rpi: Add simple RTC driver for Raspberry Pi
-
-This supports setting and reading the real time clock
-and supports wakeup alarms.
-
-To support wake up alarms you want this bootloader config:
- POWER_OFF_ON_HALT=1
- WAKE_ON_GPIO=0
-
-You can test with:
- echo +600 | sudo tee /sys/class/rtc/rtc0/wakealarm
- sudo halt
-
-That will halt (in an almost no power state),
-then wake and restart after 10 minutes.

-+* Raspberry Pi RTC
-+
-+This is a Linux interface to an RTC managed by firmware, hence it's
-+virtual from a Linux perspective.
-+
-+The interface uses the firmware mailbox api to access the RTC registers.
-+
-+Required properties:
-+compatible: should be "raspberrypi,rpi-rtc"
-+firmware: Reference to the RPi firmware device node.
-+
-+Example:

-+ rpi_rtc: rpi_rtc {

-Subject: [PATCH] hwmon: (pwm-fan) Add fan speed register support
-
-Some platforms include a fan-speed register that reports RPM directly
-as an alternative to counting interrupts from the fan tachometer input.
-Add support for reading a register at a given offset (rpm-offset) within
-a block declared in another node (rpm-regmap). This indirection allows
-the usual address mapping to be performed, and for address sharing with
-another driver.

-
-LBM allocations need a different size depending on the line length,
-format, etc.
-
-This can get tricky, and fail. Let's add some more prints to ease the
-debugging when it does.

-
-The vc4_plane_atomic_check() directly returns the result of the final
-function it calls.
-
-Using the already defined ret variable to check its content on error,
-and a separate return 0 on success, makes it easier to extend.

-Subject: [PATCH] drm/vc4: Introduce generation number enum
-
-With the introduction of the BCM2712 support, we will get yet another
-generation of display engine to support.
-
-The binary check of whether it's VC5 or not thus doesn't work anymore,
-especially since some parts of the driver will have changed with BCM2711,
-and some others with BCM2712.
-
-Let's introduce an enum to store the generation the driver is running
-on, which should provide more flexibility.

-Subject: [PATCH] drm/vc4: Make v3d paths unavailable on any generation newer
- than vc4
-
-The V3D IP has been separate since BCM2711, so let's make sure we issue
-a WARN if we're running not only on BCM2711, but also anything newer.

-Subject: [PATCH] drm/vc4: hvs: Test if the EOF interrupts are enabled
-
-We currently enable the EOF interrupts through the CRTC destroy_state
-implementation.
-
-However, nothing guarantees that we can't call destroy_state multiple
-times in a row, and therefore before the EOF interrupt even happens.
-
-This means we would enable the interrupt multiple times but disable it
-only once. It wasn't an issue so far since the interrupts were only
-enabled by setting a bit in a register, but with BCM2712 we will use an
-external interrupt controller, with a refcounted interrupt.

-
-Just like the HVS itself, the COB parameters will be fairly different in
-the BCM2712.
-
-Let's move the COB parameters computation and its initialisation to a
-separate function that will be easier to extend in the future.

-
-With the introduction of the support for BCM2712, the check of whether
-we're running on vc5 or not to compute the LBM alignment requirement
-doesn't work anymore.
-
-Moreover, the LBM size will need to be computed in words for the
-BCM2712, while we've had sizes in bytes so far.
-
-Aligning on either 64 or 32 words is thus fairly harmful on BCM2712, so
-let's just explicitly align the size when needed, and then call
-drm_mm_insert_node_generic() with an alignment of 1.

-Subject: [PATCH] drm/vc4: hvs: Change prototype of __vc4_hvs_alloc to pass
- registers
-
-The BCM2712 HVS has registers to report the size of the various SRAM the
-driver uses, and their size actually differ depending on the stepping.
-
-The initialisation of the memory pools happen in the __vc4_hvs_alloc()
-function that also allocates the main HVS structure, that will then hold
-the pointer to the memory mapping of the registers.
-
-This creates some kind of circular dependency that we can break by
-passing the mapping pointer as an argument for __vc4_hvs_alloc() to use
-to query to get the SRAM sizes and initialise the memory pools
-accordingly.

-Subject: [PATCH] drm/vc4: Move the buffer offset out of the vc4_plane_state
-
-The offset fields in vc4_plane_state are described as being
-the offset for each buffer in the bo, however it is used to
-store the complete DMA address that is then written into the
-register.
-
-The DMA address including the fb ofset can be retrieved
-using drm_fb_dma_get_gem_addr, and the offset adjustment due to
-clipping is local to vc4_plane_mode_set.
-Drop the offset field from the state, and compute the complete
-DMA address in vc4_plane_mode_set.

-Subject: [PATCH] drm/vc4: hvs: Remove ABORT_ON_EMPTY flag
-
-ABORT_ON_EMPTY chooses whether the HVS abandons the current frame
-when it experiences an underflow, or attempts to continue.
-
-In theory the frame should be black from the point of underflow,
-compared to a shift of sebsequent pixels to the left.
-
-Unfortunately it seems to put the HVS is a bad state where it is not
-possible to recover simply. This typically requires a reboot
-following the 'flip done timed out message'.
-
-Discussion with Broadcom has suggested we don't use this flag.
-All their testing is done with it disabled.
-
-Additionally setting BLANK_INSERT_EN causes the HDMI to output
-blank pixels on an underflow which avoids it losing sync.
-
-After this change a 'flip done timed out' due to sdram bandwidth
-starvation or too low a clock is recoverable once the situation improves.

-
-The HVS found in the BCM2712, while having a similar role, is very
-different from the one found in the previous SoCs. Indeed, the register
-layout is fairly different, and the DLIST format is new as well.
-
-Let's introduce the needed functions to support the new HVS.

-Subject: [PATCH] drm/vc4: crtc: Add support for BCM2712 PixelValves
-
-The PixelValves found on the BCM2712 are similar to the ones found in
-the previous generation.
-
-Compared to BCM2711, the pixelvalves only drive one HDMI controller each
-and HDMI1 PixelValve has a FIFO long enough to support 4k at 60Hz.

-
-The HDMI controllers found in the BCM2712 are largely the ones found in
-the BCM2711 with a different PHY.
-
-There's some difference with how timings are split between registers,
-and HDMI1 is now able to run at 4k/60Hz.

-Subject: [PATCH] drm/vc4: txp: Add support for BCM2712 MOP
-
-The BCM2712 has an evolution of what used to be called TXP in the
-earlier SoCs, but is now called MOP.
-
-There's a few differences still, so we can add a new compatible to deal
-with them easily.

-Hook the proper implementations of reset, duplicate_state, destroy and

-The BCM2712 comes with a different LBM size computation than the
-previous generations, so let's add the few examples provided as kunit
-tests to make sure we always satisfy those requirements.

-Subject: [PATCH] drm/vc4: kms: Avoid setting core and disp clocks for hdmi
- modes
-
-On 2712, the firmware always runs these clock at a speed sufficient
-for dual 4kp60.
-
-The requests here prevent the gpu from going into its lowest voltage
-mode, so just skip the clock requests.
-
-With this applied the idle voltage on my pi 5 reduces from 0.7424V
-to 0.72V.

-vc4 has always fixed up the timing, so the values defined have

-The display appears to want a slightly longer HFP, so extend

-Subject: [PATCH] ASoC: hdmi-codec: Fix broken channel map reporting
-
-Commit b84b53149476b22cc3b8677b771fb4cf06d1d455 upstream.
-
-Commit 4e0871333661 ("ASoC: hdmi-codec: fix channel info for
-compressed formats") accidentally changed hcp->chmap_idx from
-ca_id, the CEA channel allocation ID, to idx, the index to
-the table of channel mappings ordered by preference.
-
-This resulted in wrong channel maps being reported to userspace,
-eg for 5.1 "FL,FR,LFE,FC" was reported instead of the expected
-"FL,FR,LFE,FC,RL,RR":
-
-~ # speaker-test -c 6 -t sine
-...
- 0 - Front Left
- 3 - Front Center
- 1 - Front Right
- 2 - LFE
- 4 - Unknown
- 5 - Unknown
-
-~ # amixer cget iface=PCM,name='Playback Channel Map' | grep ': values'
- : values=3,4,8,7,0,0,0,0
-
-Switch this back to ca_id in case of PCM audio so the correct channel
-map is reported again and set it to HDMI_CODEC_CHMAP_IDX_UNKNOWN in
-case of non-PCM audio so the PCM channel map control returns "Unknown"
-channels (value 0).
-
-Fixes: 4e0871333661 ("ASoC: hdmi-codec: fix channel info for compressed formats")

-Subject: [PATCH] media: rp1: cfe: Fix use of freed memory on errors
-
-cfe_probe_complete() calls cfe_put() on both success and fail code paths.
-This works for the success path, but causes the cfe_device struct to be
-freed, even if it will be used later in the teardown code.
-
-Fix this by making the ref handling a bit saner: Let the video nodes
-have the refs as they do now, but also keep a ref in the "main" driver,
-released only at cfe_remove() time. This way the driver does not depend
-on the video nodes keeping the refs.

-Subject: [PATCH] media: rp1: cfe: Fix width & height in cfe_start_channel()
-
-The logic for handling width & height in cfe_start_channel() is somewhat
-odd and, afaics, broken. The code reads:
-
-bool start_fe = is_fe_enabled(cfe) &&
- test_all_nodes(cfe, NODE_ENABLED, NODE_STREAMING);
-
-if (start_fe || is_image_output_node(node)) {
- width = node->fmt.fmt.pix.width;
- height = node->fmt.fmt.pix.height;
-}
-
-cfe_start_channel() is called for all video nodes that will be used. So
-this means that if, say, fe_stats is enabled as the last node, start_fe
-will be true, and width and height will be taken from fe_stats' node.
-The width and height will thus contain garbage, which then gets
-programmed to the csi2 registers.
-
-It seems that this often still works fine, though, probably if the width
-& height are large enough.
-
-Drop the above code, and instead get the width & height from the csi2
-subdev's sink pad for the csi2 channel that is used. For metadata the
-width & height will be 0 as before.

-Subject: [PATCH] media: rp1: cfe: Rename xxx_dbg_irq() to xxx_dbg_verbose()
-
-Rename the xxx_dbg_irq() macros to xxx_dbg_verbose(), as they can be
-used to verbose debugs outside irq context too.

-Subject: [PATCH] media: rp1: csi2: Track CSI-2 errors
-
-Track the errors from the CSI-2 receiver: overflows and discards. These
-are recorded in a table which can be read by the userspace via debugfs.
-
-As tracking the errors may cause much more interrupt load, the tracking
-needs to be enabled with a module parameter.
-
-Note that the recording is not perfect: we only record the last
-discarded DT for each discard type, instead of recording all of them.
-This means that e.g. if the device is discarding two unmatched DTs, the
-debugfs file only shows the last one recorded. Recording all of them
-would need a more sophisticated recording system to avoid the need of a
-very large table, or dynamic allocation.

-Subject: [PATCH] vc4/drm: Remove the clear of SCALER_DISPBKGND_FILL
-
-Since "drm/vc4: hvs: Support BCM2712 HVS" booting Pi4
-with dual 4kp30 displays connected fails with:
-vc4-drm gpu: [drm] *ERROR* [CRTC:107:pixelvalve-4] flip_done timed out
-
-It has been tracked down to the referenced commit adding a
-path to clear the SCALER_DISPBKGND_FILL when not required.
-
-Dual 4kp30 works with a core clock of 297MHz when background fill
-is enabled, but requires a higher value with it disabled.
-320MHz still fails, while 330MHz seems okay.
-
-Lets always enable background fill for Pi0-4.

-Subject: [PATCH] media/rpivid: Allow use of iommu in rpivid
-
-In order to use iommu on hevc set dma mask_and_coherent in probe.
-I am assured dma_set_mask_and_coherent is benign on Pi4 (which has
-no iommu) and it seems to be so in practice.
-Also adds a bit of debug to make internal buffer allocation failure
-easier to spot in future

- startup
-
-When polled without the use of IRQ, FT5x06 registers may return
-undefined initial data, causing unwanted touches or event spamming.
-A simple way to filter this out is to suppress touches until the
-TD_STATUS register changes for the first time.
-
-Increase the delay before first polling to 300ms, to avoid
-transient I2C read flakiness that seems to occur after reset.

-Subject: [PATCH] vc_mem: Add the DMA memcpy support from bcm2708_fb
-
-bcm2708_fb is disabled by the vc4-kms-v3d overlay, which means that the
-DMA memcpy support it provides is not available to allow vclog to read
-the VC logs from the top 16MB on Pi 2 and Pi 3. Add the code to the
-vc_mem driver, which will still be enabled.
-
-It ought to be possible to do a proper DMA_MEM_TO_MEM copy via the
-generic DMA customer API, but that can be a later step.

-Subject: [PATCH] drm/vc4: Correct address offset for planes with src_[xy]
- offsets
-
-11cf37e741b4 switched to using drm_fb_dma_get_gem_addr instead of
-drm_fb_dma_get_gem_obj and adding fb->offset[].
-
-However the tiled formats need to compute the offset in a more
-involved manner than drm_fb_dma_get_gem_addr applies, and we
-were ending up with the offset for src_[xy] being applied twice.
-
-Switch back to using drm_fb_dma_get_gem_obj and fully computing
-the offsets ourselves.
-
-Fixes: 11cf37e741b4 ("drm/vc4: Move the buffer offset out of the vc4_plane_state")

- format
-
-Now that we have removed unique PISP media bus codes, the cfe format
-table has multiple entries with the same media bus code for 16-bit
-formats. The test in cfe_video_link_validate() did not account for this.
-Fix it by testing the media bus code and the V4L2 pixelformat 4cc
-together.
-
-As a drive-by, ensure we have a valid CSI2 datatype id when programming
-the hardware block.

-Subject: [PATCH] dt: Add overrides for drm framebuffer allocations on Pi5
-
-Adds dtparam overrides to the base Pi5 DT such that vc4,
-DSI0, DSI1, or DPI can be requested to be /dev/fb[012].
-No override is specified by default, so the order will be
-based on probe order (aka semi-random). Any device that
-doesn't have an override specified will be placed above
-all specified overrides. Having an fb1 or fb2 override but
-no fb0 one will result in no console via fbcon.

-Subject: [PATCH] fixup! overlays: mcp23017: allow specification of the i2c bus
-
-The incorrect fragment order (*) caused broke the interrupt usage, and
-while it was being fixed the lack of a reference to the pinctrl
-declaration was noticed.
-
-See: https://github.com/raspberrypi/linux/issues/5677

-(*) Ideally all fragments would appear in the file in the order in which
-they should be merged, but that is easy to forget and can be awkward, so
-the firmware merges all "intra" fragments (those that target other
-fragments in the overlay) before "inter" fragments (those that target
-the base DTB). However, intra fragments that target other intra
-fragments is a level of nesting too far for this logic to cope, so they
-must appear before the fragments they target.

-
-The code handling freeing stale dlists had 2 issues:
-- it disabled the interrupt as soon as the first EOF interrupt
- occurred, even if it didn't clear all stale allocations, thus
- leading to stale entries
-- It didn't free stale entries from disabled channels, so eg
- "kmstest -c 0" could leave a stale alloc on channel 1 floating
- around.
-
-Keep the interrupt enabled whilst there are any outstanding
-allocs, and discard those on disabled channels. This second
-channel does require us to call vc4_hvs_stop_channel from
-vc4_crtc_atomic_disable so that the channel actually gets stopped.

-Subject: [PATCH] drm/vc4: crtc: Support odd horizontal timings on BCM2712
-
-BCM2711 runs pixelvalve at two pixels per clock cycle which results
-in an unfortunate limitation that odd horizontal timings are not
-possible. This is apparent on the standard DMT mode of 1366x768@60
-which cannot be driven with correct timing.
-
-BCM2712 defaults to the same behaviour, but has a mode to support
-odd timings. While internally it still runs at two pixels per clock,
-setting the PV_VCONTROL_ODD_TIMING bit makes it appear externally
-to behave as it is one pixel per clock.
-
-Switching to this mode fixes 1366x768@60 mode, and other custom
-resultions with odd horizontal timings.

-
-With a DMA FIFO threshold greater than 1 (encoded as 0), it is possible
-for data in the FIFO to be inaccessible, causing the transfer to fail
-after a timeout. If the transfer includes a transmission, reduce the
-RX threshold when the TX completes, otherwise use 1 for the whole

-Subject: [PATCH] drivers: mmc: sdhci: add SPURIOUS_INT_RESP quirk
-
-Certain controllers (dwc-mshc) generate timeout conditions separately to
-command-completion conditions, where the end result is interrupts are
-separated in time depending on the current SDCLK frequency.
-
-This causes spurious interrupts if SDCLK is slow compared to the CPU's
-ability to process and return from interrupt. This occurs during card
-probe with an empty slot where all commands that would generate a
-response time out.
-
-Add a quirk to squelch command response interrupts when a command
-timeout interrupt is received.

-
-It is permitted for a plane to be configured such that none
-of it is on-screen via either negative dest rectangle X,Y
-offset, or just an offset that is greater than the crtc
-dimensions.
-
-These planes were resized via drm_atomic_helper_check_plane_state
-such that the source rectangle had a zero width or height, but
-they still created a dlist entry even though they contributed
-no pixels. In the case of vc6_plane_mode_set, that it could result
-in negative values being written into registers, which caused
-incorrect behaviour.
-
-Drop planes that result in a source width or height of 0 pixels
-to avoid the incorrect rendering.

-Subject: [PATCH] drm: vc4: Block swiotlb bounce buffers being imported as
- dmabuf
-
-The dmabuf import already checks that the backing buffer is contiguous
-and rejects it if it isn't. vc4 also requires that the buffer is
-in the bottom 1GB of RAM, and this is all correctly defined via
-dma-ranges.
-
-However the kernel silently uses swiotlb to bounce dma buffers
-around if they are in the wrong region. This relies on dma sync
-functions to be called in order to copy the data to/from the
-bounce buffer.
-
-DRM is based on all memory allocations being coherent with the
-GPU so that any updates to a framebuffer will be acted on without
-the need for any additional update. This is fairly fundamentally
-incompatible with needing to call dma_sync_ to handle the bounce
-buffer copies, and therefore we have to detect and reject mappings
-that use bounce buffers.

-Subject: [PATCH] drm/vc4: Set TV margins on the composite connector state
-MIME-Version: 1.0
-Content-Type: text/plain; charset=UTF-8
-Content-Transfer-Encoding: 8bit
-
-The Raspberry Pi bootloader can pass a set of margin values to the
-kernel cmdline as part of the video= option. These should result in
-black borders on the output to compensate for TVs where the visible area
-on the screen is smaller than the full extents of the video image.
-
-With the VC4 driver this currently works on an HDMI connector, but not
-on a composite video connector.
-
-The TV margins from the kernel cmdline are available in the
-drm_cmdline_mode structure of the composite video connector. Apply them
-to the connector state in the connector reset function. This is how it
-is implemented for the VC4 HDMI connector.

-Subject: [PATCH] dtoverlays: Add option for cam0 to camera-mux-Nport overlays
-
-Seeing as the mux can be connected to either CAM/DISP1 or
-CAM/DISP0 on a Pi5, add a cam0 override to allow configuration
-of which is used. Default (as with all camera overlays) is CAM/DISP1.
-
-The overlay does NOT update the camera regulator used by all the
-sensors as doing so would be a nightmare. The Arducam mulitplexer
-boards these overlays are initially supporting seem to tie the
-regulator GPIO for all the sensors high anyway.
-If it was viewed as necessary, then creating an additional
-regulator that listed cam[01]_reg as the parent should work.

-Subject: [PATCH] drm/panel: add panel-dsi
-
-Equivalent to panel-dpi for configuring a simple DSI panel with
-device tree side timings and bus settings.
-Motiviation is the same as for panel-dpi of wanting to support
-new simple panels without needing to patch the kernel.

-Subject: [PATCH] dts: bcm2712: put usb under /axi not /soc
-
-On 2712, the DWC USB controller is no longer attached to the Videocore
-30-bit bus with its associated aliases, and can see the bottom 4GB of
-RAM directly.
-
-Ideally it should make use of IOMMU6 but for now software bounce buffers
-get it working.

-Subject: [PATCH] media: Add MIPI CCI register access helper functions
-
-The CSI2 specification specifies a standard method to access camera sensor
-registers called "Camera Control Interface (CCI)".
-
-This uses either 8 or 16 bit (big-endian wire order) register addresses
-and supports 8, 16, 24 or 32 bit (big-endian wire order) register widths.
-
-Currently a lot of Linux camera sensor drivers all have their own custom
-helpers for this, often copy and pasted from other drivers.
-
-Add a set of generic helpers for this so that all sensor drivers can
-switch to a single common implementation.
-
-These helpers take an extra optional "int *err" function parameter,
-this can be used to chain a bunch of register accesses together with
-only a single error check at the end, rather than needing to error
-check each individual register access. The first failing call will
-set the contents of err to a non 0 value and all other calls will
-then become no-ops.

-
-The CSI-2 subdev's set_fmt currently allows setting the source and sink
-pad formats quite freely. This is not right, as the CSI-2 block can only
-do one of the following when processing the stream: 1) pass through as
-is, 2) expand to 16-bits, 3) compress.
-
-The csi2_pad_set_fmt() should take this into account, and only allow

-
-pisp_fe_pad_set_fmt() allows setting the pad formats quite freely. This
-is not correct, and the function should only allow formats as supported
-by the hardware. Fix this by:
-
-Allow no format changes for FE_CONFIG_PAD and FE_STATS_PAD. They should
-always be the hardcoded initial ones.
-
-Allow setting FE_STREAM_PAD freely (but the mbus code must be
-supported), and propagate the format to the FE_OUTPUT0_PAD and
-FE_OUTPUT1_PAD pads.
-
-Allow changing the mbus code for FE_OUTPUT0_PAD and FE_OUTPUT1_PAD pads
-only if the mbus code is the compressed version of the sink side code.
-
-TODO: FE supports scaling and cropping. This should be represented here
-too?

-Subject: [PATCH] media: rp1: csi2: Use get_frame_desc to get CSI-2 VC and DT
-
-Use get_frame_desc pad op for asking the CSI-2 VC and DT from the source
-device driver, instead of hardcoding to VC 0, and getting the DT from a
-formats table. To keep backward compatibility with sources that do not
-implement get_frame_desc, implement a fallback mechanism that always
-uses VC 0, and gets the DT from the formats table, based on the CSI2's
-sink pad's format.

-Subject: [PATCH] media: rp1: cfe: Add is_image_node()
-
-The hardware supports streaming from memory (in addition to streaming
-from the CSI-2 RX), but the driver does not support this at the moment.
-
-There are multiple places in the driver which uses
-is_image_output_node(), even if the "output" part is not relevant. Thus,
-in a minor preparation for the possible support for streaming from
-memory, and to make it more obvious that the pieces of code are not
-about the "output", add is_image_node() which will return true for both
-input and output video nodes.
-
-While at it, reformat also the metadata related macros to fit inside 80
-columns.

-Subject: [PATCH] media: rp1: cfe: Dual purpose video nodes
-
-The RP1 CSI-2 DMA can capture both video and metadata just fine, but at
-the moment the video nodes are only set to support either video or
-metadata.
-
-Make the changes to support both video and metadata. This mostly means
-tracking both video format and metadata format separately for each video
-node, and using vb2_queue_change_type() to change the vb2 queue type
-when needed.
-
-Briefly, this means that the user can get/set both video and meta
-formats to a single video node. The vb2 queue buffer type will be
-changed when the user calls REQBUFS or CREATE_BUFS ioctls. This buffer
-type will be then used as the "mode" for the video node when the user
-starts the streaming, and based on that either the video or the meta
-format will be used.
-
-A bunch of macros are added (node_supports_xxx()), which tell if a node
-can support a particular mode, whereas the existing macros
-(is_xxx_node()) will tell if the node is currently in a particular mode.
-Note that the latter will only work correctly between the start of the
-streaming and the end of the streaming, and thus should be only used in
-those code paths.
-
-However, as the userspace (libcamera) does not support dual purpose
-video nodes, for the time being let's keep the second video node as
-V4L2_CAP_META_CAPTURE only to keep the userspace working.

-
-The driver registers for line-end interrupts, but never uses them. This
-just causes extra interrupt load, with more complexity in the driver.
-
-Drop the LE handling. It can easily be added back if later needed.

-
-Improve the link validation for metadata by:
-- Allowing capture buffers that are larger than the incoming frame
- (instead of requiring exact match).
-
-- Instead of assuming that a metadata unit ("pixel") is 8 bits, use
- find_format_by_code() to get the format and use the bit depth from
- there. E.g. bit depth for RAW10 metadata will be 10 bits, when we
- move to the upstream metadata formats.

-Printing the prefix is generally "12-3456 " which is 8 desired
-characters (the length of EDT_NAME_PREFIX_LEN) and the NULL.
-The space is therefore being truncated to fit the NULL in.
-
-Increase the length snprintf is allowed to use.

-Subject: [PATCH] drivers: media: cfe: Add more robust ISR handlers
-
-Update the ISR logic to be more robust to sensors in problematic states
-where interrupts may start arriving overlapped and/or missing.
-
-1) Test for cur_frame in the FE handler, and if present, dequeue it in
-an error state so that it does not get orphaned.
-
-2) Move the sequence counter and timestamp variables to the node
-structures. This allows the ISR to track channels running ahead when
-interrupts arrive unordered.
-
-3) Add a test to ensure we don't have a spurios (but harmlesS) call to
-the FE handler in some circumstances.

-Subject: [PATCH] spi: bcm2835: Support spi0-0cs and SPI_NO_CS mode
-
-The forced conversion of native CS lines into software CS lines is done
-whether or not the controller has been given any CS lines to use. This
-breaks the use of the spi0-0cs overlay to prevent SPI from claiming any
-CS lines, particularly with spidev which doesn't pass in the SPI_NO_CS
-flag at creation.
-
-Use the presence of an empty cs-gpios property as an indication that no
-CS lines should be used, bypassing the native CS conversion code.

-On allocation failure clear out ALL stale entries, and retry the

-Subject: [PATCH 1252/1295] Improvement on backup-switchover-mode overlay value
- definitions (#5884)
-
-For the RV3028 RTC, the definitions for its `backup-switchover-mode` overlay
-were not intelligible neither complete/exhaustive.
-
-Accordingly to the https://github.com/raspberrypi/linux/issues/2912#issuecomment-477670051
-these one here proposed should be correct.
-
-`/boot/config.txt` should be as a configuration example, for rv3028, on a
- Uputronics GPS Extension HAT:
-
- # For GPS Expansion Board from Uputronics
- dtparam=i2c_arm=on
- dtoverlay=i2c-rtc,rv3028,backup-switchover-mode=3
- dtoverlay=pps-gpio,gpiopin=18
- init_uart_baud=115200
-
-From my tests (`sudo rmmod rtc_rv3028 && sudo i2cget -y 1 0x52 0x37`):
-
-`Default from factory`: `0x10`
-`Mode 0`: `0x10`
-`Mode 1`: `0x14`
-`Mode 2`: `0x18`
-`Mode 3`: `0x1c`
-
-`Mode 3`: `0x1c` is consistent with the manufacturer configuration script: http://store.uputronics.com/files/configure-rv3028.sh

-
-Since bcm2712-iommu{,-cache}.c doesn't have usual module descriptors
-such as `MODULE_LICENSE`, configuring this as 'M' fails the build with
-`ERROR: modpost: missing MODULE_LICENSE() in <...>/bcm2712-iommu.o`.
-Since it seems like the code is not intended to be built as a module
-anyway (it registers the driver with `builtin_platform_driver()`), don't

-
-According to kconfig-language.txt [1], select should be used only for
-"non-visible symbols ... and for symbols with no dependencies". Since
-MFD_RP1 both is visible and has a dependency, "select" should not be
-used and "depends on" should be used instead.
-
-In particular, this fixes the build of this kernel tree on NixOS, where

-Subject: [PATCH 1262/1295] Update touch PiTFT overlays
-
-Expose the invert and swap touch parameters on 2.8" and 3.5" resistive touchscreens. Add
-the DRM parameter to the PiTFT 2.2" and 2.8" Capacitive overlay in the same
-way it is on the resistive overlays. Change the DRM driver to `adafruit,yx240qv29`
-because the rotations are consistent with the FBTFT Driver. Fix the override size parameters
-on the 2.8" capacitive PiTFT.

-Subject: [PATCH 1266/1295] ASoC: adds support for AMP4 Pro to the DAC Plus
- driver
-
-The AMP4 Pro is a I2S master mode capable amplifier with
-clean onboard clock generators.
-We can share the card driver between TAS575x amplifiers
-and the PCM512x DACs as they are SW compatible.
-From a HW perspective though we need to limit the sample
-rates to the standard audio rates to avoid running the
-onboard clocks through the PLL. Using the PLL would require
-even a different HW.
-DAI/stream name are also set accordingly to allow the user
-a convenient identification of the soundcard
-
-Needs the pcm512x driver with TAS575x support (already in
-upstream kernel).

- embedded buffer
-
-Increase the size of the default embedded buffer to 16k. This is done to
-match what is advertised by the IMX219 driver and workaround a problem
-where the embedded stream is not actually used. Without full streams API
-support, the media pipeline validation will fail in these circumstances.

-MIME-Version: 1.0
-Content-Type: text/plain; charset=UTF-8
-Content-Transfer-Encoding: 8bit
-
-Currently, the V3D driver uses PAGE_SHIFT over the assumption that
-PAGE_SHIFT = 12, as the PAGE_SIZE = 4KB. But, the RPi 5 is using
-PAGE_SIZE = 16KB, so the MMU PAGE_SHIFT is different than the system's
-PAGE_SHIFT.
-
-Enable V3D to be used in system's with any PAGE_SIZE by making sure that
-everything MMU-related uses the MMU page shift.

- overlays for Hifiberry DAC+
-
-As the easy switching of the I2S module bewteen clock producer/consumer
-on the PI5 is not possible, two specific DT-overlays are introduced.
-The DAC+PRO boards with onboard clocks use the -PRO overlay, the boards
-without oscillators the -STD version.
-The "hifiberry-dacplus,slave" parameter in the -STD overlay disables
-the automatic clock detection inside the hifiberry-dacplus driver.
-
-The former hifiberry-dacplus overlay is kept for compatibility but
-will be deprecated.

- Hifiberry DACplusADC
-
-As we have never released a (standard) DACplusADC board with onboard
-clocks, we can simply use a fixed setup avoiding incompatibilities
-with Pi5 during driver init. Setting 'hifiberry-dacplusadc,slave' in
-the overlays disables the failing clock probing mechanism.
-
-Removes 'slave' parameter description from README which is still
-supported but not needed.
