From: Arnd Bergmann <[email protected]>
As part of removing all board files that were previously marked as unused,
I looked through the davinci platform and recursively removed everything
that has now become unused.
In particular, this is for all dm3xx support, in addition to the dm64xx
support removed previously. The remaining support is now for da8xx using
devicetree only, which means a lot of the da8xx specific device support
can also go away.
As with the previous series, I can keep patches together in the
soc tree, or subsystem maintainers can pick them up individually
through their subsystems, whichever they prefer.
Arnd Bergmann (14):
ARM: davinci: remove unused board support
ARM: davinci: drop DAVINCI_DMxxx references
ARM: davinci: clean up platform support
clk: remove davinci dm3xx drivers
usb: musb: remove unused davinci support
mfd: remove dm355evm_msp driver
input: remove davinci keyboard driver
rtc: remove davinci rtc driver
ASoC: remove unused davinci support
mfd: remove davinci voicecodec driver
pata: remove palmchip bk3710 driver
irqchip: remove davinci aintc driver
staging: media: remove davinci vpfe_capture driver
media: davinci: remove vpbe support

2.29.2
From: Arnd Bergmann <[email protected]>
The musb-davinci driver was only used on dm644x, which got removed
in linux-6.0. The only remaining davinci machines are da8xx
devicetree based and do not use this hardware.

- *
- * - See musb_{host,gadget}.c for more info
- *
- * - Correct RX DMA generally forces the engine into irq-per-packet mode,
- * which can easily saturate the CPU under non-mass-storage loads.
- *
- * NOTES 24-aug-2006 (2.6.18-rc4):
- *
- * - peripheral RXDMA wedged in a test with packets of length 512/512/1.
- * evidently after the 1 byte packet was received and acked, the queue
- * of BDs got garbaged so it wouldn't empty the fifo. (rxcsr 0x2003,
- * and RX DMA0: 4 left, 80000000 8feff880, 8feff860 8feff860; 8f321401
- * 004001ff 00000001 .. 8feff860) Host was just getting NAKed on tx
- * of its next (512 byte) packet. IRQ issues?
- *
- * REVISIT: the "transfer DMA" glue between CPPI and USB fifos will
- * evidently also directly update the RX and TX CSRs ... so audit all
- * host and peripheral side DMA code to avoid CSR access after DMA has
- * been started.

- * CPPI TX:
- * ========

- * (except how it handles the exactly-N-packets case). Building a
- * txdma queue with multiple requests (urb or usb_request) looks
- * like it would work ... but fault handling would need much testing.
- *
- * The main issue with TX mode RNDIS relates to transfer lengths that
- * are an exact multiple of the packet length. It appears that there's
- * a hiccup in that case (maybe the DMA completes before the ZLP gets
- * written?) boiling down to not being able to rely on CPPI writing any
- * terminating zero length packet before the next transfer is written.
- * So that's punted to PIO; better yet, gadget drivers can avoid it.
- *
- * Plus, there's allegedly an undocumented constraint that rndis transfer
- * length be a multiple of 64 bytes ... but the chip doesn't act that
- * way, and we really don't _want_ that behavior anyway.
- *
- * On TX, "transparent" mode works ... although experiments have shown
- * problems trying to use the SOP/EOP bits in different USB packets.
- *
- * REVISIT try to handle terminating zero length packets using CPPI
- * instead of doing it by PIO after an IRQ. (Meanwhile, make Ethernet
- * links avoid that issue by forcing them to avoid zlps.)

- * CPPI RX Woes:
- * =============
- * Consider a 1KB bulk RX buffer in two scenarios: (a) it's fed two 300 byte
- * packets back-to-back, and (b) it's fed two 512 byte packets back-to-back.
- * (Full speed transfers have similar scenarios.)
- *
- * The correct behavior for Linux is that (a) fills the buffer with 300 bytes,
- * and the next packet goes into a buffer that's queued later; while (b) fills
- * the buffer with 1024 bytes. How to do that with CPPI?
- *
- * - RX queues in "rndis" mode -- one single BD -- handle (a) correctly, but
- * (b) loses **BADLY** because nothing (!) happens when that second packet
- * fills the buffer, much less when a third one arrives. (Which makes this
- * not a "true" RNDIS mode. In the RNDIS protocol short-packet termination
- * is optional, and it's fine if peripherals -- not hosts! -- pad messages
- * out to end-of-buffer. Standard PCI host controller DMA descriptors
- * implement that mode by default ... which is no accident.)
- *
- * - RX queues in "transparent" mode -- two BDs with 512 bytes each -- have
- * converse problems: (b) is handled right, but (a) loses badly. CPPI RX
- * ignores SOP/EOP markings and processes both of those BDs; so both packets
- * are loaded into the buffer (with a 212 byte gap between them), and the next
- * buffer queued will NOT get its 300 bytes of data. (It seems like SOP/EOP
- * are intended as outputs for RX queues, not inputs...)
- *
- * - A variant of "transparent" mode -- one BD at a time -- is the only way to
- * reliably make both cases work, with software handling both cases correctly
- * and at the significant penalty of needing an IRQ per packet. (The lack of
- * I/O overlap can be slightly ameliorated by enabling double buffering.)
- *
- * So how to get rid of IRQ-per-packet? The transparent multi-BD case could
- * be used in special cases like mass storage, which sets URB_SHORT_NOT_OK
- * (or maybe its peripheral side counterpart) to flag (a) scenarios as errors
- * with guaranteed driver level fault recovery and scrubbing out what's left
- * of that garbaged datastream.
- *
- * But there seems to be no way to identify the cases where CPPI RNDIS mode
- * is appropriate -- which do NOT include RNDIS host drivers, but do include
- * the CDC Ethernet driver! -- and the documentation is incomplete/wrong.
- * So we can't _ever_ use RX RNDIS mode ... except by using a heuristic
- * that applies best on the peripheral side (and which could fail rudely).
- *
- * Leaving only "transparent" mode; we avoid multi-bd modes in almost all
- * cases other than mass storage class. Otherwise we're correct but slow,
- * since CPPI penalizes our need for a "true RNDIS" default mode.
- */
-
-
-/* Heuristic, intended to kick in for ethernet/rndis peripheral ONLY
- *
- * IFF
- * (a) peripheral mode ... since rndis peripherals could pad their
- * writes to hosts, causing i/o failure; or we'd have to cope with
- * a largely unknowable variety of host side protocol variants
- * (b) and short reads are NOT errors ... since full reads would
- * cause those same i/o failures
- * (c) and read length is
- * - less than 64KB (max per cppi descriptor)
- * - not a multiple of 4096 (g_zero default, full reads typical)
- * - N (>1) packets long, ditto (full reads not EXPECTED)
- * THEN
- * try rx rndis mode
- *
- * Cost of heuristic failing: RXDMA wedges at the end of transfers that
- * fill out the whole buffer. Buggy host side usb network drivers could
- * trigger that, but "in the field" such bugs seem to be all but unknown.
- *
- * So this module parameter lets the heuristic be disabled. When using

From: Arnd Bergmann <[email protected]>
The dm644x and dm3xx SoCs have been removed, as have the
da850_evm/da830_evm machines, the remaining machines all use the
DT based probing and do not use the vcif driver.

2.29.2
From: Arnd Bergmann <[email protected]>
The ASoC davinci voicecodec support is no longer used after
the removal of the dm3xx SoC platform, so the MFD driver is never
selected.

2.29.2
From: Arnd Bergmann <[email protected]>
The davinci dm3xx/dm644x platforms are gone now, and the remaining
da8xx platforms do not use the vpbe driver, so the driver can be
removed as well.

-The VPBE V4L2 driver design
-===========================
-
-Functional partitioning
------------------------
-
-Consists of the following:
-
- 1. V4L2 display driver
-
- Implements creation of video2 and video3 device nodes and
- provides v4l2 device interface to manage VID0 and VID1 layers.
-
- 2. Display controller
-
- Loads up VENC, OSD and external encoders such as ths8200. It provides
- a set of API calls to V4L2 drivers to set the output/standards
- in the VENC or external sub devices. It also provides
- a device object to access the services from OSD subdevice
- using sub device ops. The connection of external encoders to VENC LCD
- controller port is done at init time based on default output and standard
- selection or at run time when application change the output through
- V4L2 IOCTLs.
-
- When connected to an external encoder, vpbe controller is also responsible
- for setting up the interface between VENC and external encoders based on
- board specific settings (specified in board-xxx-evm.c). This allows
- interfacing external encoders such as ths8200. The setup_if_config()
- is implemented for this as well as configure_venc() (part of the next patch)
- API to set timings in VENC for a specific display resolution. As of this
- patch series, the interconnection and enabling and setting of the external
- encoders is not present, and would be a part of the next patch series.
-
- 3. VENC subdevice module
-
- Responsible for setting outputs provided through internal DACs and also
- setting timings at LCD controller port when external encoders are connected
- at the port or LCD panel timings required. When external encoder/LCD panel
- is connected, the timings for a specific standard/preset is retrieved from
- the board specific table and the values are used to set the timings in
- venc using non-standard timing mode.
-
- Support LCD Panel displays using the VENC. For example to support a Logic
- PD display, it requires setting up the LCD controller port with a set of
- timings for the resolution supported and setting the dot clock. So we could
- add the available outputs as a board specific entry (i.e add the "LogicPD"
- output name to board-xxx-evm.c). A table of timings for various LCDs
- supported can be maintained in the board specific setup file to support
- various LCD displays.As of this patch a basic driver is present, and this
- support for external encoders and displays forms a part of the next
- patch series.
-
- 4. OSD module
-
- OSD module implements all OSD layer management and hardware specific
- features. The VPBE module interacts with the OSD for enabling and
- disabling appropriate features of the OSD.
-
-Current status
---------------
-
-A fully functional working version of the V4L2 driver is available. This
-driver has been tested with NTSC and PAL standards and buffer streaming.

- * Driver name : VPFE Capture driver
- * VPFE Capture driver allows applications to capture and stream video
- * frames on DaVinci SoCs (DM6446, DM355 etc) from a YUV source such as
- * TVP5146 or Raw Bayer RGB image data from an image sensor
- * such as Microns' MT9T001, MT9T031 etc.
- *
- * These SoCs have, in common, a Video Processing Subsystem (VPSS) that
- * consists of a Video Processing Front End (VPFE) for capturing
- * video/raw image data and Video Processing Back End (VPBE) for displaying
- * YUV data through an in-built analog encoder or Digital LCD port. This
- * driver is for capture through VPFE. A typical EVM using these SoCs have
- * following high level configuration.
- *
- * decoder(TVP5146/ YUV/
- * MT9T001) --> Raw Bayer RGB ---> MUX -> VPFE (CCDC/ISIF)
- * data input | |
- * V |
- * SDRAM |
- * V
- * Image Processor
- * |
- * V
- * SDRAM
- * The data flow happens from a decoder connected to the VPFE over a
- * YUV embedded (BT.656/BT.1120) or separate sync or raw bayer rgb interface
- * and to the input of VPFE through an optional MUX (if more inputs are
- * to be interfaced on the EVM). The input data is first passed through
- * CCDC (CCD Controller, a.k.a Image Sensor Interface, ISIF). The CCDC
- * does very little or no processing on YUV data and does pre-process Raw
- * Bayer RGB data through modules such as Defect Pixel Correction (DFC)
- * Color Space Conversion (CSC), data gain/offset etc. After this, data
- * can be written to SDRAM or can be connected to the image processing
- * block such as IPIPE (on DM355 only).
- *
- * Features supported
- * - MMAP IO
- * - Capture using TVP5146 over BT.656
- * - support for interfacing decoders using sub device model
- * - Work with DM355 or DM6446 CCDC to do Raw Bayer RGB/YUV
- * data capture to SDRAM.
- * TODO list
- * - Support multiple REQBUF after open
- * - Support for de-allocating buffers through REQBUF
- * - Support for Raw Bayer RGB capture
- * - Support for chaining Image Processor
- * - Support for static allocation of buffers
- * - Support for USERPTR IO
- * - Support for STREAMON before QBUF
- * - Support for control ioctls

Shouldn't the else case be kept since it applies to *all* "other devices"?
(and therfore the usb_resources shouldn't be modified either?)

.num_resources is already initialized to 2 from ARRAY_SIZE(),
so it does not have to be changed afterwards.

Great, one less pata/ide driver !
I can queue this in ata tree. I do have some changes in ata Kconfig queued
already, but they should not conflict.

As discussed on irc, it is best if you merge this to due dependencies on
arch/arm/mach-davinci/davinci.h.
Note that there is one more reference to vpfe_capture.h:
Documentation/userspace-api/ioctl/ioctl-number.rst:'V' C0 media/davinci/vpfe_capture.h conflict!
Feel free to fold that in this patch, or make a separate patch removing it.
If you make a separate patch, then you can add my Acked-by for that change.
Regards,
Hans
