Hi Matthias,

As the vdosys0 previous reviewed patch:

https://patchwork.kernel.org/project/linux-mediatek/patch/20220927152704.12018-2-jason-jh.lin@mediatek.com/
Should I modify the vdosys0 items format like your example?

Or should vdosys1 add items format like vdosys0's previous patch?
    - items:
        - const: mediatek,mt8195-vdosys1
        - const: mediatek,mt8195-mmsys
        - const: syscon

Regards,
Jason-JH.Lin
