Merge tag 'drm-next-2019-09-18' of git://anongit.freedesktop.org/drm/drm

Pull drm updates from Dave Airlie:
 "This is the main pull request for 5.4-rc1 merge window. I don't think
  there is anything outstanding so next week should just be fixes, but
  we'll see if I missed anything. I landed some fixes earlier in the
  week but got delayed writing summary and sending it out, due to a mix
  of sick kid and jetlag!

  There are some fixes pending, but I'd rather get the main merge out of
  the way instead of delaying it longer.

  It's also pretty large in commit count and new amd header file size.
  The largest thing is four new amdgpu products (navi12/14, arcturus and
  renoir APU support).

  Otherwise it's pretty much lots of work across the board, i915 has
  started landing tigerlake support, lots of icelake fixes and lots of
  locking reworking for future gpu support, lots of header file rework

Hans Verkuil d4e0f82ac8 media: pixfmt-compressed.rst: improve H264/HEVC/MPEG1+2/VP8+9 documentation
The existing documentation was incorrect and did not correspond
to how actual codec drivers implemented this.

Update the documentation to explicitly specify what is actually
expected.

Tomasz Figa 051f8d2d86 media: docs-rst: Document memory-to-memory video decoder interface
Due to complexity of the video decoding process, the V4L2 drivers of
stateful decoder hardware require specific sequences of V4L2 API calls
to be followed. These include capability enumeration, initialization,
decoding, seek, pause, dynamic resolution change, drain and end of
stream.

Specifics of the above have been discussed during Media Workshops at
LinuxCon Europe 2012 in Barcelona and then later Embedded Linux
Conference Europe 2014 in Düsseldorf. The de facto Codec API that
originated at those events was later implemented by the drivers we already
have merged in mainline, such as s5p-mfc or coda.

The only thing missing was the real specification included as a part of
Linux Media documentation. Fix it now and document the decoder part of
the Codec API.

Maxime Jourdan 60a039eb27 media: videodev2.h: add V4L2_FMT_FLAG_DYN_RESOLUTION
Add an enum_fmt format flag to specifically tag coded formats where
dynamic resolution switching is supported by the device.

This is useful for some codec drivers that can support dynamic
resolution switching for one or more of their listed coded formats. It
allows userspace to know whether it should extract the video parameters
itself, or if it can rely on the device to send V4L2_EVENT_SOURCE_CHANGE
when such changes are detected.

Add an enum_fmt format flag to specifically tag coded formats where
full bytestream parsing is supported by the device.

Some stateful decoders are capable of fully parsing a bytestream,
but others require that userspace pre-parses the bytestream into
frames or fields (see the corresponding pixelformat descriptions
for details).

If this flag is set, then this pre-parsing step is not required
(but still possible, of course).

Ezequiel Garcia 8cae93e090 media: uapi: h264: Add the concept of start code
Stateless decoders have different expectations about the
start code that is prepended on H264 slices. Add a
menu control to express the supported start code types
(including no start code).

Drivers are allowed to support only one start code type,
but they can support both too.

Note that this is independent of the H264 decoding mode,
which specifies the granularity of the decoding operations.
Either in frame-based or slice-based mode, this new control
will allow to define the start code expected on H264 slices.

Boris Brezillon 5604be66a5 media: uapi: h264: Add the concept of decoding mode
Some stateless decoders don't support per-slice decoding granularity
(or at least not in a way that would make them efficient or easy to use).

Expose a menu to control the supported decoding modes. Drivers are
allowed to support only one decoding but they can support both too.

To fully specify the decoding operation, we need to introduce
a start_byte_offset, to indicate where slices start.

The V4L2_PIX_FMT_H264_SLICE_RAW name was originally suggested
because the pixel format would represent H264 slices without any
start code.

However, as we will now introduce a start code menu control,
give the pixel format a more meaningful name, while it's
still early enough to do so.

When the support for serial busses was introduced in V4L2, it was decided
to use the existing parallel bus media bus pixel codes to describe them.
While this was a practical choice at the time, it necessitates choosing
which one of the many parallel mbus pixel codes to use, for on the serial
busses these formats are effectively all equivalent.

The practice has always been to use the pixel code that describes a bus
that transfers a single sample per clock. Document this.

When the application calls VIDIOC_DQBUF with the DMABUF memory type, the
v4l2_buffer structure (or v4l2_plane structures) are filled with DMA-buf
file descriptors. However, the current documentation does not explain
whether those are new file descriptors referring to the same DMA-bufs or
just the same integers as passed to VIDIOC_QBUF back in time. Clarify
