This patchset introduces support for VDEC video hardware decoder
and VENC video hardware encoder of STMicroelectronics STM32MP25
SoC series.
This initial support implements H264 decoding, VP8 decoding and
JPEG encoding.
This has been tested on STM32MP257F-EV1 evaluation board.
===========
= history =
===========
version 5:
- Precise that video decoding as been successfully tested up to full HD
- Add Nicolas Dufresne reviewed-by
version 4:
- Fix comments from Nicolas about dropping encoder raw steps
version 3:
- Fix remarks from Krzysztof Kozlowski:
- drop "items", we keep simple enum in such case
- drop second example - it is the same as the first
- Drop unused node labels as suggested by Conor Dooley
- Revisit min/max resolutions as suggested by Nicolas Dufresne
version 2:
- Fix remarks from Krzysztof Kozlowski on v1:
- single video-codec binding for both VDEC/VENC
- get rid of "-names"
- use of generic node name "video-codec"
version 1:
- Initial submission
