Commit Message

Irui Wang March 12, 2021, 7:35 a.m. UTC
Updates binding document since the avc and vp8 hardware encoder in
MT8173 are now separated. Separate "mediatek,mt8173-vcodec-enc" to
"mediatek,mt8173-vcodec-enc-vp8" and "mediatek,mt8173-vcodec-enc".

This patch separates the two devices, it's a preparing patch for adding
device_link between the larbs and venc-device. It's mainly for fixing
the problem:

This is not a compatible change. That needs to be explained here with 
why that is okay.
