-Subject: [PATCH 002/222] Add bcm2708_gpio driver
-
-Signed-off-by: popcornmix <popcornmix@gmail.com>
-
-bcm2708: Add extension to configure internal pulls
-
-The bcm2708 gpio controller supports internal pulls to be used as pull-up,
-pull-down or being entirely disabled. As it can be useful for a driver to
-change the pull configuration from it's default pull-down state, add an
-extension which allows configuring the pull per gpio.
-
-Signed-off-by: Julian Scheel <julian@jusst.de>
-
-bcm2708-gpio: Revert the use of pinctrl_request_gpio
-
-In non-DT systems, pinctrl_request_gpio always fails causing
-"requests probe deferral" messages. In DT systems, it isn't useful
-because the reference counting is independent of the normal pinctrl
-pin reservations.
-
-gpio: Only clear the currently occurring interrupt. Avoids losing interrupts
-
-See: linux #760
-
-bcm2708_gpio: Avoid calling irq_unmask for all interrupts
-
-When setting up the interrupts, specify that the handle_simple_irq
-handler should be used. This leaves interrupt acknowledgement to
-the caller, and prevents irq_unmask from being called for all
-interrupts.
-
-Issue: linux #760

-
-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
-devices are active at once.
-
-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.
-
-USB fix using a FIQ to implement split transactions
-
-This commit adds a FIQ implementaion that schedules
-the split transactions using a FIQ so we don't get
-held off by the interrupt latency of Linux
-
-dwc_otg: fix device attributes and avoid kernel warnings on boot
-
-dcw_otg: avoid logging function that can cause panics
-
-See: https://github.com/raspberrypi/firmware/issues/21
-Thanks to cleverca22 for fix
-
-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: make fiq_split_enable imply fiq_fix_enable
-
-Failing to set up the FIQ correctly would result in
-"IRQ 32: nobody cared" errors in dmesg.
-
-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
-
-Issuing low-speed packets when the root port is in full-speed mode
-causes the root port to stop responding. Explicitly fail when
-enqueuing URBs to a LS endpoint on a FS bus.
-
-Fix ARM architecture issue with local_irq_restore()
-
-If local_fiq_enable() is called before a local_irq_restore(flags) where
-the flags variable has the F bit set, the FIQ will be erroneously disabled.
-
-Fixup arch_local_irq_restore to avoid trampling the F bit in CPSR.
-
-Also fix some of the hacks previously implemented for previous dwc_otg
-incarnations.
-
-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
-
-fiq_fsm: Handle HC babble errors
-
-The HCTSIZ transfer size field raises a babble interrupt if
-the counter wraps. Handle the resulting interrupt in this case.
-
-dwc_otg: fix interrupt registration for fiq_enable=0
-
-Additionally make the module parameter conditional for wherever
-hcd->fiq_state is touched.
-
-fiq_fsm: Enable by default
-
-dwc_otg: Fix various issues with root port and transaction errors
-
-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.
-
-fiq_fsm: fix build on bcm2708 and bcm2709 platforms
-
-dwc_otg: put some barriers back where they should be for UP
-
-bcm2709/dwc_otg: Setup FIQ on core 1 if >1 core active
-
-dwc_otg: fixup read-modify-write in critical paths
-
-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.
-
-Also get rid of the useless return value.
-
-squash: dwc_otg: Allow to build without SMP
-
-usb: core: make overcurrent messages more prominent
-
-Hub overcurrent messages are more serious than "debug". Increase loglevel.
-
-usb: dwc_otg: Don't use dma_to_virt()
-
-Commit 6ce0d20 changes dma_to_virt() which breaks this driver.
-Open code the old dma_to_virt() implementation to work around this.
-
-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
-chance that this driver will also work on ARCH_BCM2835.
-
-transfer_buffer should not be NULL if the length is set, but the
-comment in the code indicates that there are situations where this
-might happen. drivers/usb/isp1760/isp1760-hcd.c also has a similar
-comment pointing to a possible: 'usb storage / SCSI bug'.

-+ * 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.

-+ *
-+ * 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
-+ * can write a hardware-agnostic gadget driver running inside a USB device.
-+ *
-+ * Hardware details are visible (see CONFIG_USB_ZERO_* below) but don't
-+ * affect most of the driver.
-+ *
-+ * 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
-+ * driver does).

-+ * The dwc_otg_driver module provides the initialization and cleanup entry
-+ * points for the DWC_otg driver. This module will be dynamically installed
-+ * after Linux is booted using the insmod command. When the module is
-+ * installed, the dwc_otg_driver_init function is called. When the module is
-+ * removed (using rmmod), the dwc_otg_driver_cleanup function is called.
-+ *
-+ * This module also defines a data structure for the dwc_otg_driver, which is
-+ * used in conjunction with the standard ARM lm_device structure. These
-+ * structures allow the OTG driver to comply with the standard Linux driver
-+ * model in which devices and drivers are registered with a bus driver. This
-+ * has the benefit that Linux can expose attributes of the driver and device
-+ * in its special sysfs file system. Users can then read or write files in
-+ * this file system to perform diagnostics on the driver components or the

-+ * 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)

-+ *
-+ * 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.

-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.

-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.

-From bd7ed510e2ee47dc4338cc049c004e0451a0ccc9 Mon Sep 17 00:00:00 2001
-From: Florian Meier <florian.meier@koalo.de>
-Date: Fri, 22 Nov 2013 14:22:53 +0100
-Subject: [PATCH 007/222] 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.
-
-Signed-off-by: Noralf Trønnes <noralf@tronnes.org>
-
-bcm2708-dmaengine: Add debug options
-
-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
-
-Signed-off-by: Noralf Trønnes <noralf@tronnes.org>
-
-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.

-From: gellert <gellert@raspberrypi.org>
-Date: Fri, 15 Aug 2014 16:35:06 +0100
-Subject: [PATCH 008/222] 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.
-
-Signed-off-by: Noralf Trønnes <noralf@tronnes.org>
-
-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}.
-
-Signed-off-by: Noralf Trønnes <noralf@tronnes.org>
-
-bcm2835-mmc: Add locks when accessing sdhost registers
-
-bcm2835-mmc: Add range of debug options for slowing things down
-
-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.
-
-Signed-off-by: Noralf Trønnes <noralf@tronnes.org>
-
-BCM270x_DT: add bcm2835-mmc entry
-
-Add Device Tree entry for bcm2835-mmc.
-In non-DT mode, don't add the device in the board file.

-From 74c824df73fca559e8d4114051f66eab362b441e Mon Sep 17 00:00:00 2001
-From: Phil Elwell <phil@raspberrypi.org>
-Date: Wed, 25 Mar 2015 17:49:47 +0000
-Subject: [PATCH 009/222] 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.

-From: popcornmix <popcornmix@gmail.com>
-Date: Mon, 26 Mar 2012 22:15:50 +0100
-Subject: [PATCH 011/222] bcm2708: alsa sound driver
-MIME-Version: 1.0
-Content-Type: text/plain; charset=UTF-8
-Content-Transfer-Encoding: 8bit
-
-Signed-off-by: popcornmix <popcornmix@gmail.com>
-
-alsa: add mmap support and some cleanups to bcm2835 ALSA driver
-
-snd-bcm2835: Add support for spdif/hdmi passthrough
-
-This adds a dedicated subdevice which can be used for passthrough of non-audio
-formats (ie encoded a52) through the hdmi audio link. In addition to this
-driver extension an appropriate card config is required to make alsa-lib
-support the AES parameters for this device.
-
-snd-bcm2708: Add mutex, improve logging
-
-Fix for ALSA driver crash
-
-Avoids an issue when closing and opening vchiq where a message can arrive before service handle has been written
-
-alsa: reduce severity of expected warning message
-
-snd-bcm2708: Fix dmesg spam for non-error case
-
-alsa: Ensure mutexes are released through error paths
-
-alsa: Make interrupted close paths quieter
-
-BCM270x: Add onboard sound device to Device Tree
-
-Add Device Tree support to alsa driver.
-Add device to Device Tree.
-Don't add platform devices when booting in DT mode.

-VCHIQ: Make service closure fully synchronous (drv)
-
-This is one half of a two-part patch, the other half of which is to
-the vchiq_lib user library. With these patches, calls to
-vchiq_close_service and vchiq_remove_service won't return until any
-associated callbacks have been delivered to the callback thread.
-
-VCHIQ: Add per-service tracing
-
-The new service option VCHIQ_SERVICE_OPTION_TRACE is a boolean that
-toggles tracing for the specified service.
-
-This commit also introduces vchi_service_set_option and the associated
-option VCHI_SERVICE_OPTION_TRACE.
-
-vchiq: Make the synchronous-CLOSE logic more tolerant
-
-vchiq: Move logging control into debugfs
-
-vchiq: Take care of a corner case tickled by VCSM
-
-Closing a connection that isn't fully open requires care, since one
-side does not know the other side's port number. Code was present to
-handle the case where a CLOSE is sent immediately after an OPEN, i.e.
-before the OPENACK has been received, but this was incorrectly being
-used when an OPEN from a client using port 0 was rejected.
-
-(In the observed failure, the host was attempting to use the VCSM
-service, which isn't present in the 'cutdown' firmware. The failure
-was intermittent because sometimes the keepalive service would
-grab port 0.)
-
-This case can be distinguished because the client's remoteport will
-still be VCHIQ_PORT_FREE, and the srvstate will be OPENING. Either
-condition is sufficient to differentiate it from the special case
-described above.
-
-vchiq: Avoid high load when blocked and unkillable
-
-vchiq: Include SIGSTOP and SIGCONT in list of signals not-masked by vchiq to allow gdb to work
-
-vchiq_arm: Complete support for SYNCHRONOUS mode
-
-vchiq: Remove inline from suspend/resume
-
-vchiq: Allocation does not need to be atomic
-
-vchiq: Fix wrong condition check
-
-The log level is checked from within the log call. Remove the check in the call.

-BCM270x: Add vchiq device to platform file and Device Tree
-
-Prepare to turn the vchiq module into a driver.

-
-bcm2708: vchiq: Add Device Tree support
-
-Turn vchiq into a driver and stop hardcoding resources.
-Use devm_* functions in probe path to simplify cleanup.
-A global variable is used to hold the register address. This is done
-to keep this patch as small as possible.
-Also make available on ARCH_BCM2835.
-Based on work by Lubomir Rintel.

-+** Functions to modify the state variables;
-+**	set_suspend_state
-+**	set_resume_state
-+**
-+** There are more state variables than we might like, so ensure they remain in
-+** step.  Suspend and resume state are maintained separately, since most of
-+** these state machines can operate independently.  However, there are a few
-+** states where state transitions in one state machine cause a reset to the
-+** other state machine.  In addition, there are some completion events which
-+** need to occur on state machine reset and end-state(s), so these are also
-+** dealt with in these functions.
-+**
-+** In all states we set the state variable according to the input, but in some
-+** cases we perform additional steps outlined below;
-+**
-+** VC_SUSPEND_IDLE - Initialise the suspend completion at the same time.
-+**			The suspend completion is completed after any suspend
-+**			attempt.  When we reset the state machine we also reset
-+**			the completion.  This reset occurs when videocore is
-+**			resumed, and also if we initiate suspend after a suspend
-+**			failure.
-+**
-+** VC_SUSPEND_IN_PROGRESS - This state is considered the point of no return for
-+**			suspend - ie from this point on we must try to suspend
-+**			before resuming can occur.  We therefore also reset the
-+**			resume state machine to VC_RESUME_IDLE in this state.
-+**
-+** VC_SUSPEND_SUSPENDED - Suspend has completed successfully. Also call
-+**			complete_all on the suspend completion to notify
-+**			anything waiting for suspend to happen.
-+**
-+** VC_SUSPEND_REJECTED - Videocore rejected suspend. Videocore will also
-+**			initiate resume, so no need to alter resume state.
-+**			We call complete_all on the suspend completion to notify
-+**			of suspend rejection.
-+**
-+** VC_SUSPEND_FAILED - We failed to initiate videocore suspend.  We notify the
-+**			suspend completion and reset the resume state machine.
-+**
-+** VC_RESUME_IDLE - Initialise the resume completion at the same time.  The
-+**			resume completion is in it's 'done' state whenever
-+**			videcore is running.  Therfore, the VC_RESUME_IDLE state
-+**			implies that videocore is suspended.
-+**			Hence, any thread which needs to wait until videocore is
-+**			running can wait on this completion - it will only block
-+**			if videocore is suspended.
-+**
-+** VC_RESUME_RESUMED - Resume has completed successfully.  Videocore is running.
-+**			Call complete_all on the resume completion to unblock
-+**			any threads waiting for resume.	 Also reset the suspend
-+**			state machine to it's idle state.
-+**
-+** VC_RESUME_FAILED - Currently unused - no mechanism to fail resume exists.

-From: Tim Gover <tgover@broadcom.com>
-Date: Tue, 22 Jul 2014 15:41:04 +0100
-Subject: [PATCH 014/222] vcsm: VideoCore shared memory service for BCM2835
-
-Add experimental support for the VideoCore shared memory service.
-This allows user processes to allocate memory from VideoCore's
-GPU relocatable heap and mmap the buffers. Additionally, the memory
-handles can passed to other VideoCore services such as MMAL, OpenMax
-and DispmanX
-
-TODO
-* This driver was originally released for BCM28155 which has a different
-  cache architecture to BCM2835. Consequently, in this release only
-  uncached mappings are supported. However, there's no fundamental
-  reason which cached mappings cannot be support or BCM2835
-* More refactoring is required to remove the typedefs.
-* Re-enable the some of the commented out debug-fs statistics which were
-  disabled when migrating code from proc-fs.
-* There's a lot of code to support sharing of VCSM in order to support
-  Android. This could probably done more cleanly or perhaps just
-  removed.

-vcsm: Use boolean as it cannot be built as module
-
-On building the bcm_vc_sm as a module we get the following error:
-
-v7_dma_flush_range and do_munmap are undefined in vc-sm.ko.
-
-Fix by making it not an option to build as module
-

-Subject: [PATCH 016/222] lirc: added support for RaspberryPi GPIO
-
-lirc_rpi: Use read_current_timer to determine transmitter delay. Thanks to jjmz and others
-See: https://github.com/raspberrypi/linux/issues/525
-
-lirc: Remove restriction on gpio pins that can be used with lirc
-
-Compute Module, for example could use different pins
-
-lirc_rpi: Add parameter to specify input pin pull
-
-Depending on the connected IR circuitry it might be desirable to change the
-gpios internal pull from it pull-down default behaviour. Add a module
-parameter to allow the user to set it explicitly.
-
-Signed-off-by: Julian Scheel <julian@jusst.de>
-
-lirc-rpi: Use the higher-level irq control functions
-
-This module used to access the irq_chip methods of the
-gpio controller directly, rather than going through the
-standard enable_irq/irq_set_irq_type functions. This
-caused problems on pinctrl-bcm2835 which only implements
-the irq_enable/disable methods and not irq_unmask/mask.
-
-lirc-rpi: Correct the interrupt usage
-
-1) Correct the use of enable_irq (i.e. don't call it so often)
-2) Correct the shutdown sequence.
-3) Avoid a bcm2708_gpio driver quirk by setting the irq flags earlier
-
-lirc-rpi: use getnstimeofday instead of read_current_timer
-
-read_current_timer isn't guaranteed to return values in
-microseconds, and indeed it doesn't on a Pi2.
-
-Issue: linux#827
-
-lirc-rpi: Add device tree support, and a suitable overlay
-
-The overlay supports DT parameters that match the old module
-parameters, except that gpio_in_pull should be set using the
-strings "up", "down" or "off".
-
-lirc-rpi: Also support pinctrl-bcm2835 in non-DT mode

-+ * lirc_rpi - Device driver that records pulse- and pause-lengths
-+ *	      (space-lengths) (just like the lirc_serial driver does)
-+ *	      between GPIO interrupt events on the Raspberry Pi.
-+ *	      Lots of code has been taken from the lirc_serial module,
-+ *	      so I would like say thanks to the authors.

-Subject: [PATCH 019/222] Add Chris Boot's spi driver.
-
-spi: bcm2708: add device tree support
-
-Add DT support to driver and add to .dtsi file.
-Setup pins and spidev in .dts file.
-SPI is disabled by default.
-
-Signed-off-by: Noralf Tronnes <notro@tronnes.org>
-
-BCM2708: don't register SPI controller when using DT
-
-The device for the SPI controller is in the Device Tree.
-Only register the device when not using DT.
-
-Signed-off-by: Noralf Tronnes <notro@tronnes.org>
-
-spi: bcm2835: make driver available on ARCH_BCM2708
-
-Make this driver available on ARCH_BCM2708
-
-Signed-off-by: Noralf Tronnes <notro@tronnes.org>
-
-bcm2708: Remove the prohibition on mixing SPIDEV and DT
-
-spi-bcm2708: Prepare for Common Clock Framework migration
-
-As part of migrating to use the Common Clock Framework, replace clk_enable()
-with clk_prepare_enable() and clk_disable() with clk_disable_unprepare().
-This does not affect behaviour under the current clock implementation.
-
-Also add a missing clk_disable_unprepare() in the probe error path.

-Subject: [PATCH 020/222] Add Chris Boot's i2c driver
-
-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.
-

-
-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

-V4L2: Fixes from 6by9
-
-V4L2: Fix EV values. Add manual shutter speed control
-
-V4L2 EV values should be in units of 1/1000. Corrected.
-Add support for V4L2_CID_EXPOSURE_ABSOLUTE which should
-give manual shutter control. Requires manual exposure mode
-to be selected first.
-
-Signed-off-by: Dave Stevenson <dsteve@broadcom.com>
-
-V4L2: Correct JPEG Q-factor range
-
-Should be 1-100, not 0-100
-
-Signed-off-by: Dave Stevenson <dsteve@broadcom.com>
-
-V4L2: Fix issue of driver jamming if STREAMON failed.
-
-Fix issue where the driver was left in a partially enabled
-state if STREAMON failed, and would then reject many IOCTLs
-as it thought it was streaming.
-
-Signed-off-by: Dave Stevenson <dsteve@broadcom.com>
-
-V4L2: Fix ISO controls.
-
-Driver was passing the index to the GPU, and not the desired
-ISO value.
-
-Signed-off-by: Dave Stevenson <dsteve@broadcom.com>
-
-V4L2: Add flicker avoidance controls
-
-Add support for V4L2_CID_POWER_LINE_FREQUENCY to set flicker
-avoidance frequencies.

-
-V4L2: Add support for inline H264 headers
-
-Add support for V4L2_CID_MPEG_VIDEO_REPEAT_SEQ_HEADER
-to control H264 inline headers.
-Requires firmware fix to work correctly, otherwise format
-has to be set to H264 before this parameter is set.
-
-Signed-off-by: Dave Stevenson <dsteve@broadcom.com>
-
-V4L2: Fix JPEG timestamp issue
-
-JPEG images were coming through from the GPU with timestamp
-of 0. Detect this and give current system time instead
-of some invalid value.
-
-Signed-off-by: Dave Stevenson <dsteve@broadcom.com>
-
-V4L2: Fix issue when switching down JPEG resolution.
-
-JPEG buffer size calculation is based on input resolution.

-
-V4L2: Add option to disable enum_framesizes.
-
-Gstreamer's handling of a driver that advertises
-V4L2_FRMSIZE_TYPE_STEPWISE to define the supported
-resolutions is broken. See bug
-https://bugzilla.gnome.org/show_bug.cgi?id=726521
-
-Optional parameter of gst_v4l2src_is_broken added.
-If non-zero, the driver claims not to support that
-ioctl, and gstreamer should be happy again (it
-guesses a set of defaults for itself).
-
-Signed-off-by: Dave Stevenson <dsteve@broadcom.com>
-
-V4L2: Add support for more image formats
-
-Adds YVU420 (YV12), YVU420SP (NV21), and BGR888.

-V4L2: Extend range for V4L2_CID_MPEG_VIDEO_H264_I_PERIOD
-
-Request to extend the range from the fairly arbitrary
-1000 frames (33 seconds at 30fps). Extend out to the
-max range supported (int32 value).
-Also allow 0, which is handled by the codec as only
-send an I-frame on the first frame and never again.
-There may be an exception if it detects a significant
-scene change, but there's no easy way around that.

-bcm2835-camera: stop_streaming now has a void return
-
-BCM2835-V4L2: Fix compliance test failures
-
-VIDIOC_TRY_FMT and VIDIOC_S_FMT tests were faling due
-to reporting V4L2_COLORSPACE_JPEG when the colour
-format wasn't V4L2_PIX_FMT_JPEG.
-Now reports V4L2_COLORSPACE_SMPTE170M for YUV formats.

-From e8a7ea84bd95e08fd11b88eb859526bcb9dbfceb Mon Sep 17 00:00:00 2001

-Subject: [PATCH 023/222] scripts: Add mkknlimg and knlinfo scripts from tools
- repo
-
-The Raspberry Pi firmware looks for a trailer on the kernel image to
-determine whether it was compiled with Device Tree support enabled.
-If the firmware finds a kernel without this trailer, or which has a
-trailer indicating that it isn't DT-capable, it disables DT support
-and reverts to using ATAGs.
-
-The mkknlimg utility adds that trailer, having first analysed the
-image to look for signs of DT support and the kernel version string.
-
-knlinfo displays the contents of the trailer in the given kernel image.
-
-scripts/mkknlimg: Add support for ARCH_BCM2835
-
-Add a new trailer field indicating whether this is an ARCH_BCM2835
-build, as opposed to MACH_BCM2708/9. If the loader finds this flag
-is set it changes the default base dtb file name from bcm270x...
-to bcm283y...
-
-Also update knlinfo to show the status of the field.

-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.

-+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).
-+
-+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" directive. As an example, consider the
-+popular lirc-rpi module, the Linux Infrared Remote Control driver. In the
-+pre-DT world this would be loaded from /etc/modules, with an explicit
-+"modprobe lirc-rpi" command, or programmatically by lircd. With DT enabled,
-+this becomes a line in config.txt:
-+
-+    dtoverlay=lirc-rpi
-+
-+This causes the file /boot/overlays/lirc-rpi-overlay.dtb to be loaded. By
-+default it will use GPIOs 17 (out) and 18 (in), but this can be modified using
-+DT parameters:
-+
-+    dtoverlay=lirc-rpi,gpio_out_pin=17,gpio_in_pin=13
-+
-+Parameters always have default values, although in some cases (e.g. "w1-gpio")
-+it is necessary to provided multiple overlays in order to get the desired
-+behaviour. See the list of overlays below for a description of the parameters and their defaults.
-+
-+The Overlay and Parameter Reference
-+===================================
-+
-+Name:   <The base DTB>
-+Info:   Configures the base Raspberry Pi hardware
-+Load:   <loaded automatically>

-+
-+        spi                      Set to "on" to enable the spi interfaces
-+                                 (default "off")
-+
-+        random                   Set to "on" to enable the hardware random
-+                                 number generator (default "off")
-+
-+        uart0                    Set to "off" to disable uart0 (default "on")
-+
-+        watchdog                 Set to "on" to enable the hardware watchdog
-+                                 (default "off")
-+
-+        act_led_trigger          Choose which activity the LED tracks.
-+                                 Use "heartbeat" for a nice load indicator.
-+                                 (default "mmc")
-+
-+        act_led_activelow        Set to "on" to invert the sense of the LED
-+                                 (default "off")
-+
-+        act_led_gpio             Set which GPIO to use for the activity LED
-+                                 (in case you want to connect it to an external
-+                                 device)
-+                                 (default "16" on a non-Plus board, "47" on a
-+                                 Plus or Pi 2)
-+
-+        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.

-+Troubleshooting
-+===============
-+
-+If you are experiencing problems that you think are DT-related, enable DT
-+diagnostic output by adding this to /boot/config.txt:
-+
-+    dtdebug=on
-+
-+and rebooting. Then run:
-+
-+    sudo vcdbg log msg
-+
-+and look for relevant messages.
-+

-
-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).

-Subject: [PATCH 029/222] Speed up console framebuffer imageblit function
-
-Especially on platforms with a slower CPU but a relatively high
-framebuffer fill bandwidth, like current ARM devices, the existing
-console monochrome imageblit function used to draw console text is
-suboptimal for common pixel depths such as 16bpp and 32bpp. The existing
-code is quite general and can deal with several pixel depths. By creating
-special case functions for 16bpp and 32bpp, by far the most common pixel
-formats used on modern systems, a significant speed-up is attained
-which can be readily felt on ARM-based devices like the Raspberry Pi
-and the Allwinner platform, but should help any platform using the
-fb layer.
-
-The special case functions allow constant folding, eliminating a number
-of instructions including divide operations, and allow the use of an
-unrolled loop, eliminating instructions with a variable shift size,
-reducing source memory access instructions, and eliminating excessive
-branching. These unrolled loops also allow much better code optimization
-by the C compiler. The code that selects which optimized variant is used
-is also simplified, eliminating integer divide instructions.
-
-The speed-up, measured by timing 'cat file.txt' in the console, varies
-between 40% and 70%, when testing on the Raspberry Pi and Allwinner
-ARM-based platforms, depending on font size and the pixel depth, with
-the greater benefit for 32bpp.

-Subject: [PATCH 031/222] enabling the realtime clock 1-wire chip DS1307 and
- 1-wire on GPIO4 (as a module)
-
-1-wire: Add support for configuring pin for w1-gpio kernel module
-See: https://github.com/raspberrypi/linux/pull/457
-
-Add bitbanging pullups, use them for w1-gpio
-
-Allows parasite power to work, uses module option pullup=1
-
-bcm2708: Ensure 1-wire pullup is disabled by default, and expose as module parameter
-
-Signed-off-by: Alex J Lennon <ajlennon@dynamicdevices.co.uk>
-
-w1-gpio: Add gpiopin module parameter and correctly free up gpio pull-up pin, if set
-
-Signed-off-by: Alex J Lennon <ajlennon@dynamicdevices.co.uk>
-
-w1-gpio: Sort out the pullup/parasitic power tangle

-Subject: [PATCH 034/222] ASoC: Add support for BCM2708
-
-This driver adds support for digital audio (I2S)
-for the BCM2708 SoC that is used by the
-Raspberry Pi. External audio codecs can be
-connected to the Raspberry Pi via P5 header.
-
-It relies on cyclic DMA engine support for BCM2708.
-
-Signed-off-by: Florian Meier <florian.meier@koalo.de>
-
-ASoC: BCM2708: Add 24 bit support
-
-This adds 24 bit support to the I2S driver of the BCM2708.
-Besides enabling the 24 bit flags, it includes two bug fixes:
-
-MMAP is not supported. Claiming this leads to strange issues
-when the format of driver and file do not match.
-
-The datasheet states that the width extension bit should be set
-for widths greater than 24, but greater or equal would be correct.
-This follows from the definition of the width field.
-
-Signed-off-by: Florian Meier <florian.meier@koalo.de>
-
-bcm2708-i2s: Update bclk_ratio to more correct values
-
-Move GPIO setup to hw_params.
-
-This is used to stop the I2S driver from breaking
-the GPIO setup for other uses of the PCM interface
-
-Configure GPIOs for I2S based on revision/card settings
-
-With RPi model B+, assignment of the I2S GPIO pins has changed.
-This patch uses the board revision to auto-detect the GPIOs used
-for I2S. It also allows sound card drivers to set the GPIOs that
-should be used. This is especially important with the Compute
-Module.
-
-bcm2708-i2s: Avoid leak from iomap when accessing gpio
-
-bcm2708: Eliminate i2s debugfs directory error
-
-Qualify the two regmap ranges uses by bcm2708-i2s ('-i2s' and '-clk')
-to avoid the name clash when registering debugfs entries.

-The i2s driver used to claim to support MMAP, but that feature was disabled
-when some problems were found. Add the ability to enable this feature
-through Device Tree, using the i2s-mmap overlay.

-Subject: [PATCH 040/222] ASoC: wm8804: Implement MCLK configuration options,
- add 32bit support WM8804 can run with PLL frequencies of 256xfs and 128xfs
- for most sample rates. At 192kHz only 128xfs is supported. The existing
- driver selects 128xfs automatically for some lower samples rates. By using an
- additional mclk_div divider, it is now possible to control the behaviour.
- This allows using 256xfs PLL frequency on all sample rates up to 96kHz. It
- should allow lower jitter and better signal quality. The behavior has to be
- controlled by the sound card driver, because some sample frequency share the
- same setting. e.g. 192kHz and 96kHz use 24.576MHz master clock. The only
- difference is the MCLK divider.
-
-This also added support for 32bit data.

-Add a parameter to turn off SPDIF output if no audio is playing
-
-This patch adds the paramater auto_shutdown_output to the kernel module.
-Default behaviour of the module is the same, but when auto_shutdown_output
-is set to 1, the SPDIF oputput will shutdown if no stream is playing.
-
-bugfix for 32kHz sample rate, was missing

-HiFiBerry Digi: set SPDIF status bits for sample rate
-
-The HiFiBerry Digi driver did not signal the sample rate in the SPDIF status bits.
-While this is optional, some DACs and receivers do not accept this signal. This patch
-adds the sample rate bits in the SPDIF status block.

-
-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.

-Subject: [PATCH 047/222] 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.

-Subject: [PATCH 048/222] Added driver for HiFiBerry Amp amplifier add-on board
-
-The driver contains a low-level hardware driver for the TAS5713 and the
-drivers for the Raspberry Pi I2S subsystem.
-
-TAS5713: return error if initialisation fails
-
-Existing TAS5713 driver logs errors during initialisation, but does not return
-an error code. Therefore even if initialisation fails, the driver will still be
-loaded, but won't work. This patch fixes this. I2C communication error will now
-reported correctly by a non-zero return code.
-
-HiFiBerry Amp: fix device-tree problems
-
-Some code to load the driver based on device-tree-overlays was missing. This is added by this patch.

-Subject: [PATCH 049/222] bcm2708: Allow option card devices to be configured
- via DT
-
-If the kernel is built with Device Tree support, and if a DT blob
-is provided for the kernel at boot time, then the platform devices
-for option cards are not created. This avoids both the need to
-blacklist unwanted devices, and the need to update the board
-support code with each new device.

-Subject: [PATCH 053/222] BCM270x_DT: Add pwr_led, and the required "input"
- trigger
-
-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.

-Subject: [PATCH 058/222] pinctrl-bcm2835: Fix interrupt handling for GPIOs
- 28-31 and 46-53
-
-Contrary to the documentation, the BCM2835 GPIO controller actually has
-four interrupt lines - one each for the three IRQ groups and one common. Rather
-confusingly, the GPIO interrupt groups don't correspond directly with the GPIO
-control banks. Instead, GPIOs 0-27 generate IRQ GPIO0, 28-45 GPIO1 and
-46-53 GPIO2.
-
-Awkwardly, the GPIOS for IRQ GPIO1 straddle two 32-entry GPIO banks, so it is
-cleaner to split out a function to process the interrupts for a single GPIO
-bank.
-
-This bug has only just been observed because GPIOs above 27 can only be
-accessed on an old Raspberry Pi with the optional P5 header fitted, where
-the pins are often used for I2S instead.

-Subject: [PATCH 059/222] pinctrl-bcm2835: Only request the interrupts listed
- in the DTB
-
-Although the GPIO controller can generate three interrupts (four counting
-the common one), the device tree files currently only specify two. In the
-absence of the third, simply don't register that interrupt (as opposed to
-registering 0), which has the effect of making it impossible to generate
-interrupts for GPIOs 46-53 which, since they share pins with the SD card
-interface, is unlikely to be a problem.

-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

-Subject: [PATCH 077/222] ARM: bcm2835: Add the Raspberry Pi firmware driver
-
-This gives us a function for making mailbox property channel requests
-of the firmware, which is most notable in that it will let us get and
-set clock rates.

-Subject: [PATCH 087/222] 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 090/222] 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.

-N.B. The UART1 clock is derived from the core clock. The firmware

-Subject: [PATCH 099/222] spi-bcm2835: Support pin groups other than 7-11
-
-The spi-bcm2835 driver automatically uses GPIO chip-selects due to
-some unreliability of the native ones. In doing so it chooses the
-same pins as the native chip-selects would use, but the existing
-code always uses pins 7 and 8, wherever the SPI function is mapped.
-
-Search the pinctrl group assigned to the driver for pins that
-correspond to native chip-selects, and use those for GPIO chip-
-selects.

-Subject: [PATCH 106/222] vchiq_arm: Two cacheing fixes
-
-1) Make fragment size vary with cache line size
-Without this patch, non-cache-line-aligned transfers may corrupt
-(or be corrupted by) adjacent data structures.
-
-Both ARM and VC need to be updated to enable this feature. This is
-ensured by having the loader apply a new DT parameter -
-cache-line-size. The existence of this parameter guarantees that the
-kernel is capable, and the parameter will only be modified from the
-safe default if the loader is capable.
-
-2) Flush/invalidate vmalloc'd memory, and invalidate after reads

-Subject: [PATCH 107/222] BCM270X_DT: Overlay for the Fen Logic VGA666 board
-
-The VGA666 board requires GPIOs 2-21 (so no I2C or UART). Using the
-overlay (instead of a custom dt-blob.bin) has the advantage that it will
-reserve those pins and stop other devices using them (except for GPIO),
-but it does delay the point at which the output becomes valid until 2-3
-seconds after the kernel has started.

-Subject: [PATCH 109/222] mailbox: Enable BCM2835 mailbox support
-
-This mailbox driver provides a single mailbox channel to write 32-bit
-values to the VPU and get a 32-bit response.  The Raspberry Pi
-firmware uses this mailbox channel to implement firmware calls, while
-Roku 2 (despite being derived from the same firmware tree) doesn't.
-
-The driver was originally submitted by Lubomir, based on the
-out-of-tree 2708 mailbox driver.  Eric Anholt fixed it up for
-upstreaming, with the major functional change being that it now has no
-notion of multiple channels (since that is a firmware-dependent
-concept) and instead the raspberrypi-firmware driver will do that
-bit-twiddling in its own messages.
-[Jassi: made the 'mbox_chan_ops' struct as const and removed a redundant
-variable]

-Subject: [PATCH 110/222] mailbox/bcm2835: Fix mailbox full detection.
-
-With the VC reader blocked and the ARM writing, MAIL0_STA reads empty
-permanently while MAIL1_STA goes from empty (0x40000000) to non-empty
-(0x00000001-0x00000007) to full (0x80000008).
-
-This bug ended up having no effect on us, because all of our
-transactions in the client driver were synchronous and under a mutex.

-Subject: [PATCH 123/222] 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 148/222] pinctrl: bcm2835: Clear the event latch register when
- disabling interrupts
-
-It's possible to hit a race condition if interrupts are generated on a GPIO
-pin when the IRQ line in question is being disabled.
-
-If the interrupt is freed, bcm2835_gpio_irq_disable() is called which
-disables the event generation sources (edge, level). If an event occurred
-between the last disabling of hard IRQs and the write to the event
-source registers, a bit would be set in the GPIO event detect register
-(GPEDSn) which goes unacknowledged by bcm2835_gpio_irq_handler()
-so Linux complains loudly.
-
-There is no per-GPIO mask register, so when disabling GPIO interrupts
-write 1 to the relevant bit in GPEDSn to clear out any stale events.

-Subject: [PATCH 149/222] dwc_otg: fiq_fsm: Make high-speed isochronous strided
- transfers work properly
-
-Certain low-bandwidth high-speed USB devices (specialist audio devices,
-compressed-frame webcams) have packet intervals > 1 microframe.
-
-Stride these transfers in the FIQ by using the start-of-frame interrupt
-to restart the channel at the right time.

-Subject: [PATCH 151/222] bcm2835 camera planar/packed stride length
-
-Added a field to the mmal_fmt struct used to compute the bytes per line
-when using a particular format. This results in the correct stride being
-calculated even when the format is planar.

-Subject: [PATCH 154/222] BCM270X_DT: Add pwm and pwm-2chan overlays
-
-From the README entries:
-  Legal pin,function combinations for each channel:
-    PWM0: 12,4(Alt0) 18,2(Alt5) 40,4(Alt0)            52,5(Alt1)
-    PWM1: 13,4(Alt0) 19,2(Alt5) 41,4(Alt0) 45,4(Alt0) 53,5(Alt1)
-  N.B.:
-    1) Pin 18 is the only one available on all platforms, and
-       it is the one used by the I2S audio interface.
-       Pins 12 and 13 might be better choices on an A+, B+ or Pi2.
-    2) The onboard analogue audio output uses both PWM channels.
-    3) So be careful mixing audio and PWM.
-    4) Currently the clock must have been enabled and configured
-       by other means.

-less than 30us - it will only execute under those circumstances.
-So it should run comfortably without getting interrupted by the
-scheduler.
-
-But there are situations where the raspberry pi is so overloaded
-that it can take up to 80 jiffies until the polling thread gets
-rescheduled - this has been observed especially under heavy
-IO situations.
-
-In such a situation we now fall back to the interrupt handler and
-log the situation at debug level.

-Subject: [PATCH 156/222] spi: bcm2835: enable dma modes for transfers meeting
- certain conditions
-MIME-Version: 1.0
-Content-Type: text/plain; charset=UTF-8
-Content-Transfer-Encoding: 8bit
-
-Conditions per spi_transfer are:
-* transfer.len >= 96 bytes (to avoid mapping overhead costs)
-* transfer.len < 65536 bytes (limitaion by spi-hw block - could get extended)
-* an individual scatter/gather transfer length must be a multiple of 4
-  for anything but the last transfer - spi-hw block limit.
-  (some shortcut has been taken in can_dma to avoid unnecessary mapping of
-   pages which, for which there is a chance that there is a split with a
-   transfer length not a multiple of 4)
-
-If it becomes a necessity these restrictions can get removed by additional
-code.
-
-Note that this patch requires a patch to dma-bcm2835.c by Noralf to
-enable scatter-gather mode inside the dmaengine, which has not been
-merged yet.
-
-That is why no patch to arch/arm/boot/dts/bcm2835.dtsi is included - the
-code works as before without dma when tx/rx are not set, but it writes
-a message warning about dma not used:
-spi-bcm2835 20204000.spi: no tx-dma configuration found - not using dma mode
-
-To enable dma-mode add the following lines to the device-tree:
-        dmas = <&dma 6>, <&dma 7>;
-        dma-names = "tx", "rx";
-

-Subject: [PATCH 157/222] spi: bcm2835: fix kbuild compile warnings/errors and
- a typo
-
-fixes several warnings/error emmitted by the kbuild system:
-* warn: cast from pointer to integer of different size
-  using size_t instead of u32
-* error: 'SZ_4K' undeclared
-  moved to PAGE_SIZE and PAGE_MASK instead
-
-Review showed also a typo in the same code where tx_buff
-was checked twice instead of checking both rx and tx_buff.
-
-Reported by: Stephen Rothwell <sfr@canb.auug.org.au>
-Signed-off-by: Martin Sperl <kernel@martin.sperl.org>
-Signed-off-by: Mark Brown <broonie@kernel.org>
-(cherry picked from commit 7e52be0d576e8f7bc99a606f07b9d000c4340f04)

-Subject: [PATCH 163/222] 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.
-

-Subject: [PATCH 178/222] BCM270X_DT: Use fixed-factor-clock for uart1
-
-The BCM2835 mini-UART is almost 8250-compatible, but there is
-a factor-of-two difference in the clock divider for the baud rate.
-The standard 8250 driver can be used unmodified provided we lie to it
-about the clock frequency, pretending it is double the actual value.
-The mini-UART block shares the core clock, and the current firmware
-uses a DT-parameter to update the clock-frequency property. Although it
-works, this isn't ideal because it exposes the firmware to a driver
-problem.
-
-This patch uses the fixed-factor-clock module to create a clock that is
-always twice the frequency of the core clock. (N.B. These "fixed" clocks
-just describe an existing clock, rather than changing any hardware
-settings.)

- PAGE_MASK
-
-There is a bug in the alignment checking of transfers,
-that results in DMA not being used for un-aligned
-transfers that do not cross page-boundries, which is valid.
-
-This is due to a missconception of the meaning PAGE_MASK
-when implementing that check originally - (PAGE_SIZE - 1)
-should have been used instead.
-
-Also fixes a copy/paste error.

-+
-+SMI or secondary memory interface is a peripheral specific to certain Broadcom

-+and NAND flashes (in fact, most things with a parallel register interface).
-+
-+Required properties:
-+- compatible: "brcm,bcm2835-smi"
-+- reg: Should contain location and length of SMI registers and SMI clkman regs
-+- interrupts: *the* SMI interrupt.
-+- pinctrl-names: should be "default".
-+- pinctrl-0: the phandle of the gpio pin node.
-+- brcm,smi-clock-source: the clock source for clkman
-+- brcm,smi-clock-divisor: the integer clock divisor for clkman
-+- dmas: the dma controller phandle and the DREQ number (4 on a 2835)
-+- dma-names: the name used by the driver to request its channel.
-+  Should be "rx-tx".
-+
-+Optional properties:
-+- None.

-+* BCM2835 SMI NAND flash
-+
-+This driver is a shim between the BCM2835 SMI driver (SMI is a peripheral for
-+talking to parallel register interfaces) and Linux's MTD layer.
-+
-+Required properties:
-+- compatible: "brcm,bcm2835-smi-nand"
-+- status: "okay"
-+
-+Optional properties:
-+- partition@n, where n is an integer from a consecutive sequence starting at 0
-+	- Difficult to store partition table on NAND device - normally put it
-+	in the source code, kernel bootparams, or device tree (the best way!)
-+	- Sub-properties:
-+		- label: the partition name, as shown by mtdinfo /dev/mtd*
-+		- reg: the size and offset of this partition.
-+		- (optional) read-only: an empty property flagging as read only
-+
-+Example:
-+
-+nand: flash@0 {
-+	compatible = "brcm,bcm2835-smi-nand";
-+	status = "okay";
-+
-+	partition@0 {
-+		label = "stage2";
-+		// 128k
-+		reg = <0 0x20000>;
-+		read-only;
-+	};
-+	partition@1 {
-+		label = "firmware";
-+		// 16M
-+		reg = <0x20000 0x1000000>;
-+		read-only;
-+	};
-+	partition@2 {
-+		label = "root";
-+		// 2G
-+		reg = <0x1020000 0x80000000>;
-+	};

-Subject: [PATCH 194/222] 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.

-The board support code contains sufficient strings to be able to
-distinguish 2708 vs. 2835 builds, so remove the check for
-bcm2835-pm-wdt which could exist in either.
-
-Also, since the canned configuration is no longer built in (it's
-a module), remove the config string checking.

-Subject: [PATCH 200/222] 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.

-Subject: [PATCH 216/222] bcm2709_fb: refine appropriate behaviors to
- unsupported fb ioctls
-MIME-Version: 1.0
-Content-Type: text/plain; charset=UTF-8
-Content-Transfer-Encoding: 8bit
-
-since fbturbo introduces and use FBUNSUPPORTED ioctl on copyarea
-operations for unsupported dummy ioctl which is expected to return
-failure. in such scenario, bcm2709 always prompts error log.
-
-in order not to bother users in kernel log, we change the dev_err to
-dev_dbg and return a ENOTTY other than EINVAL to let userspace handles
-the return value.

-Subject: [PATCH 222/222] 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.
