From: "Jason-JH.Lin" <redacted> For previous MediaTek SoCs, such as MT8173, there are 2 display HW pipelines binding to 1 mmsys with the same power domain, the same clock driver and the same mediatek-drm driver. For MT8195, VDOSYS0 and VDOSYS1 are 2 display HW pipelines binding to 2 different power domains, different clock drivers and different mediatek-drm drivers. Therefore, we need to separate these two different mmsys hardwares to 2 different compatibles for MT8195.

If I understand correctly support for vdosys0 is merged with the old compatible. We should therefore keep mediatek,mt8195-mmsys as a fallback for mediatek,mt8195-vdosys0. Regards, Matthias
