Hi Jason,

The OVL hardware capabilities have changed starting from MT8195,

Therefore, it is necessary to update the OVL compatible from MT8183 to
MT8195.
This probably doesn't need an (immediate) respin, but this patch needs:
Fixes: 7075b21d1a8e ("arm64: dts: mediatek: mt8188: Add display nodes
for vdosys0")
No, because the binding must otherwise get a Fixes tag.
This is not a fix anyway, and is technically adding new features to the MT8188
OVL; without the additional features, the MT8188 is still compatible with the
MT8183 OVL, as much as MT8195.
