Subject: [PATCH v4,1/3] 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-enc-vp8" and "mediatek,mt8173-vcodec-enc".
This patch is not a compatible change, but we must do this modifaction
because MediaTek IOMMU add the device_link between the smi-larb
device and venc_device, if the venc device call the pm_runtime_get_sync,
the smi-larb's pm_runtime_get_sync also be called automatically.
There is a bit of backward compatibility for avc encoder, the avc
encoder device node still has compatible "mediatek,mt8173-vcodec-enc".
