This is a legacy driver and I'm convinced that we should do something to
actually *drop it forever*.

Please add support for power domains in mtk-pm-domains.c instead: if you need
a nice example about differences between the two, look at MT8173's implementation,
as that is present in both scpsys and mtk-pm-domains.

Summarizing, your MT6735 support will be about:
  - Adding soc/mediatek/mt6735-pm-domains.h
  - Adding support in mtk-pm-domains:

static const struct of_device_id scpsys_of_match[] = {
	........
	{
		.compatible = "mediatek,mt6735-power-controller",
		.data = &mt6735_scpsys_data,
	},
	.........
};

Cheers,
Angelo
