In addition to Krzysztof's review......

oneOf:
  - const: mediatek,mt8188-apu-mailbox
  - items:
    - enum:
        - mediatek,mt8195-apu-mailbox
        - mediatek,mt8196-apu-mailbox
    - const: mediatek,mt8188-apu-mailbox

should be like that - I haven't checked if this gives any warnings, but anyway
you got the point, I think.
