This breaks the schema check for mt8195.dtsi, which is currently using
`compatible = "mediatek,mt8195-disp-ovl", "mediatek,mt8183-disp-ovl";`
IIUC this is supposed to be a RESEND of [1], which actually added a
binding for "mediatek,mt8195-disp-ovl". However [1] still breaks
mt8195.dtsi because it only allows `compatible =
"mediatek,mt8195-disp-ovl"` But not `compatible =
"mediatek,mt8195-disp-ovl", "mediatek,mt8183-disp-ovl"`.
If "mediatek,mt8183-disp-ovl" is a reasonable fallback for
"mediatek,mt8195-disp-ovl", please keep a binding like:
- items:
- const: mediatek,mt8195-disp-ovl
- const: mediatek,mt8183-disp-ovl
Or, fix mt8195.dtsi instead in the same series.
