Hey Benjamin,

This series aims to make HEVC uapi stable and usable for hardware
decoder. HEVC uapi is used by 2 mainlined drivers (Cedrus and Hantro)
and 2 out of the tree drivers (rkvdec and RPI).

Why is rkvdec out-of-tree? It is in the staging directory just like
hantro and cedrus? Am I missing something here?

Greetings,
Sebastian


The 3 first patches are from Hans to implement v4l2 dynamic control
feature which is need by patch 7 for V4L2_CID_STATELESS_HEVC_ENTRY_POINT_OFFSET
definition.

Patch 4 move the existing uapi to stable, including definitions renaming
and CID number change to fit with v4l2 naming.

Patches 5 and 7 add fields needed for rkvdec and RPI decoders.

Patches 6 is cleaning up the uapi of useless field.
Patches 8 change one field description and name to define offset by
bytes rather than by bits
