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 6:
- Use a single file for VDEC and VENC variants as suggested by Alex Bee
- Fix some typos raised by Sebastian Fricke
- Add Krzysztof Kozlowski Reviewed-by
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

Sakari, Mauro, do you plan to take patches 1 to 3 on your next branch ?
I will take DT pacthes in mine but I would like to be sure that
dt-binding will be applied in a next branch (for the next v6.9 cycle);

DT patches ([4]&[5]) applied on stm32-next. I assume that dt-bindings
patch will go through the media tree.
