Subject: [PATCH 1/3] dt-bindings: media: mtk-vcodec: Separating mtk vcodec encoder node

Updates binding document since the avc and vp8 hardware encoder in
MT8173 are now separated. Separate "mediatek,mt8173-vcodec-enc" to
"mediatek,mt8173-vcodec-vp8-enc" and "mediatek,mt8173-vcodec-avc-enc".

Subject: [PATCH 2/3] arm64: dts: mt8173: Separating mtk-vcodec-enc device node

There are two separate hardware encoder blocks inside MT8173.
Split the current mtk-vcodec-enc node to match the hardware architecture.

IMHO "mediatek,mt8173-vcodec-enc-vp8" and
"mediatek,mt8173-vcodec-enc-avc" would be more logical. Also to keep a
bit of backward compatibility, shall we also allow
"mediatek,mt8173-vcodec-enc" to be an alias for
"mediatek,mt8173-vcodec-enc-avc"? The line above would become

"mediatek,mt8173-vcodec-enc-avc" or "mediatek,mt8173-vcodec-enc" for
mt8173 avc encoder.

Can't we use "venc_sel" for both avc and vp8, since they are different
nodes now? That way we can just say

encoder must contain "venc_sel"

which is clearer and also simpler on the code side.

Let's use vcodec_enc_avc as a label?

And here the label should probably be "vcodec_enc_vp8" for consistency.

This is not a compatible change. You need to detail that and why that's
okay (assuming it is).
