[v2,00/13] AV1 stateless decoder for RK3588

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.

It is based on Daniel's "[PATCH v4] media: Add AV1 uAPI" [1] patches and
Sebastian's device-tree patches for RK3588.

The full branch can be found here:
https://gitlab.collabora.com/linux/for-upstream/-/commits/rk3588_av1_decoder_v2

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 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.

Hi Benjamin,

Thanks for the patch.

Please use the v4l2_ctrl_grab API. Can you send a separate series to address
this for the other codecs?

Thanks a lot!
