[PATCH 6/9] media: mtk-vcodec: Add new venc drv interface for frame_racing mode

Irui Wang
2021-08-16T11:00:56Z

Frame-racing mode encoding need more venc working buffers, it
will break the compatibility if we just add venc_vsi in AP-Kernel
but not in firmware, so add a new venc driver interface to
distinguish the sigle_core_mode and frame_racing mode.

The new driver interface can be used for different codecs in
the future.
