[PATCH v2 0/5] Add support for video hardware codec of STMicroelectronics STM32 SoC series

[Hugues Fruchet]

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.

    - single video-codec binding for both VDEC/VENC
    - get rid of "-names"
    - use of generic node name "video-codec"

version 1:
  - Initial submission
