[PATCH v6 00/13] AV1 stateless decoder for RK3588

[Benjamin Gaignard]

This series implement AV1 stateless decoder for RK3588 SoC.
The hardware support 8 and 10 bits bitstreams up to 7680x4320.
AV1 feature like film grain or scaling are done by the postprocessor.
The driver can produce NV12_4L4, NV12_10LE40_4L4, NV12 and P010 pixels formats.
Even if Rockchip have named the hardware VPU981 it looks like a VC9000 but 
with a different registers mapping.

The series is based on Hans's br-v6.4f branch + "media: Add AV1 uAPI"
patch v7.
The full branch can be found here:
https://gitlab.collabora.com/linux/for-upstream/-/commits/rk3588_av1_decoder_v6

Fluster score is: 200/239 while testing AV1-TEST-VECTORS with GStreamer-AV1-V4L2SL-Gst1.0.
The failing tests are:
- the 2 tests with 2 spatial layers: few errors in luma/chroma values
- tests with resolution < hardware limit (64x64)
- 10bits film grain test: bad macroblocks while decoding, the same 8bits
  test is working fine.

Changes in v6:
- Rename NV12_10LE40_4L4 pixel format into NV15_4L4.
- Add defines for post-proc selection.
- Change patch order as requested by Nicolas.
- Fix frame-larger-than warning.

Changes in v5:
- Add a patch to initialize bit_depth field of V4L2_CTRL_TYPE_AV1_SEQUENCE
  ioctl.

Changes in v4:
- Squash "Save bit depth for AV1 decoder" and "Check AV1 bitstreams bit
  depth" patches.
- Double motion vectors buffer size.
- Fix the various errors reported by Hans.

Changes in v3:
- Fix arrays loops limites.
- Remove unused field.
- Reset raw pixel formats list when bit depth or film grain feature
  values change.
- Enable post-processor P010 support

Changes in v2:
- Remove useless +1 in sbs computation. 
- Describe NV12_10LE40_4L4 pixels format.
- Post-processor could generate P010.
- Fix comments done on v1.
- The last patch make sure that only post-processed formats are used when film
  grain feature is enabled.
