Hi everyone,

This patch series adds support for the Amlogic video decoder,
as well as the corresponding dt bindings for GXBB/GXL/GXM chips.

It features decoding for the following formats:
- MPEG 1
- MPEG 2

The following formats will be added in future patches:
- MJPEG
- MPEG 4 (incl. Xvid, H.263)
- H.264
- HEVC (incl. 10-bit)

The following formats' development has still not started, but they are
supported by the hardware:
- VC1
- VP9

The code was made in such a way to allow easy inclusion of those formats
in the future.

The decoder is single instance.

Files:
 - vdec.c handles the V4L2 M2M logic
 - esparser.c manages the hardware bitstream parser
 - vdec_helpers.c provides helpers to DONE the dst buffers as well as
 various common code used by the codecs
 - vdec_1.c manages the VDEC_1 block of the vdec IP
 - codec_mpeg12.c enables decoding for MPEG 1/2.
 - vdec_platform.c links codec units with vdec units
 (e.g vdec_1 with codec_mpeg12) and lists all the available
 src/dst formats and requirements (max width/height, etc.),
 per compatible chip.

Firmwares are necessary to run the vdec. They can currently be found at:
https://github.com/chewitt/meson-firmware

It was tested primarily with ffmpeg's v4l2-m2m implementation. For instance:
$ ffmpeg -c:v mpeg2_v4l2m2m -i sample_mpeg2.mkv -f null -

Note: This patch series depends on
"[PATCH v3 0/3] soc: amlogic: add meson-canvas"
https://patchwork.kernel.org/cover/10573763/

The v4l2-compliance results are available below the patch diff.

I see that there is no SHA, so you probably didn't compile this from a
checked-out git repo. Please do so, since without a SHA I don't know
whether or not you used the latest v4l2-compliance version.

Noted, FWIW the last v4l-utils commit for this run is
e37fbf50a28c1a1cfe9e00a60542bc14192a87ba (Aug. 27).

I'll make sure to compile inside the git repo for the next submission.
