I think this is "mediatek,mt8183-mmsys". In [1], Matthias has agreed that we could keep work on his patch, so you should apply his patch and remove this patch. In [2], I've found that MT8183 scpsys has some problem with Matthias' patch, so please also fix this problem.

+The Display Device power name are defined in
+include\dt-bindings\power\mt*-power.h

+Example:
+
+display_components: dispsys@14000000 {
+ compatible = "mediatek,mt8183-display";
+ reg = <0 0x14000000 0 0x1000>;
+ power-domains = <&scpsys MT8183_POWER_DOMAIN_DISP>;
+};
