Subject: [PATCH v1 0/9] AV1 stateless decoder for RK3588

This series implement AV1 stateless decoder for RK3588 SoC.
The harware 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 and NV12 pixel formats.
A native 10bits NV12_4L4 format is possible but need more investigation
to be completly documented and enabled.

It is based on Daniel's "[RFC,v3] 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_v1

Fluster score is: 151/239 while testing AV1-TEST-VECTORS with GStreamer-AV1-V4L2SL-Gst1.0.
The failing tests are:
- 10bits bitstream because 10bits output formats aren't yet implemented.
- the 2 tests with 2 spatial layers: few errors in luma/chroma values
- tests with resolution < hardware limit (64x64)
