+
+The hcd would unconditionally set the transfer length to the endpoint

+Subject: [PATCH] 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.

-Subject: [PATCH] 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.

+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.
+
+See: https://github.com/raspberrypi/linux/issues/3291
+ https://github.com/raspberrypi/linux/pull/3297

-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.
-
-See: https://github.com/raspberrypi/linux/issues/3291
- https://github.com/raspberrypi/linux/pull/3297

+Subject: [PATCH] tty: amba-pl011: Add un/throttle support
+
+The PL011 driver lacks throttle and unthrottle methods. As a result,
+sending more data to the Pi than it can immediately sink while CRTSCTS
+is enabled causes a NULL pointer to be followed.
+
+Add a throttle handler that disables the RX interrupts, and an
+unthrottle handler that reenables them.

+Subject: [PATCH] mmc: sdhci-iproc: Fix vmmc regulators on iProc
+
+The Linux support for controlling card power via regulators appears to
+be contentious. I would argue that the default behaviour is contrary to
+the SDHCI spec - turning off the power writes a reserved value to the
+SD Bus Voltage Select field of the Power Control Register, which
+seems to kill the Arasan/iProc controller - but fortunately there is a
+hook in sdhci_ops to override the behaviour. Borrow the implementation
+from sdhci_arasan_set_power.

-Subject: [PATCH] mmc: sdhci-iproc: Fix vmmc regulators on iProc
-
-The Linux support for controlling card power via regulators appears to
-be contentious. I would argue that the default behaviour is contrary to
-the SDHCI spec - turning off the power writes a reserved value to the
-SD Bus Voltage Select field of the Power Control Register, which
-seems to kill the Arasan/iProc controller - but fortunately there is a
-hook in sdhci_ops to override the behaviour. Borrow the implementation
-from sdhci_arasan_set_power.

-Subject: [PATCH] bcm2838.dtsi: Use BCM2711 PCIe compatible string
-
-The BCM2711 PCIe controller has a limited address range in the B0
-silicon, and the driver uses a compatible string to identify the
-limitation. The current Pi 4 firmware will override the compatible
-string if it detects a downstream DTB and it is running on a newer
-revision but set the default value to enable the workaround for
-backwards-compatibility with old firmware.

+
+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.

+The previous version of the dwc2 overlay set the RX FIFO size to

+
+Minas Harutyunyan at Synopsys (the source of the DWC OTG design)

+
+The addr parameter of the mcp23017 overlay was broken by the addition
+of the noints parameter; splitting the mcp node in two without also
+modifying the second half from the addr parameter would cause the two
+halves to separate. Change the implementation strategy to patch
+fragment 2 (as was originally proposed). This will prevent the
+overlay from being applied at runtime until the "dtoverlay" command

+Subject: [PATCH] overlays: add hdmi-backlight-hwhack-gpio-overlay
+
+This is a Devicetree overlay for GPIO based backlight on/off capability.
+
+Use this if you have one of those HDMI displays whose backlight cannot be controlled via DPMS over HDMI and plan to do a little soldering to use an RPi gpio pin for on/off switching.
+
+See: https://www.waveshare.com/wiki/7inch_HDMI_LCD_(C)#Backlight_Control
+
+This was tested with a clone of the Waveshare "7 inch HDMI Touch LCD C" where I soldered two mosfets to override the backlight dip-switch.
+When the overlay is loaded, a sysfs backlight node appears which can be used to modify the brightness value (0 or 1), and is even used by DPMS to switch the display backlight off after the configured timeout.
+(On current Raspbian Buster Desktop, it's also possible to wakeup the display via a tap on the touch display :-) )

+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.

+Subject: [PATCH] ARM: dts: Remove virtgpio from bcm2711-rpi-4-b.dts
+
+Pi 4B doesn't need the virtgpio driver (it was added to reduce the
+overhead of driving the ACT LED on the Pi 3B's GPIO expander), so
+remove the instantiation by the Pi 4 DTS file to avoid confusion.
