Required properties:
-- compatible: Must be "mediatek,mt8173-scpsys"
+- compatible: Should be one of:

+ - "mediatek,mt8173-scpsys"
- #power-domain-cells: Must be 1
- reg: Address range of the SCPSYS unit
- infracfg: must contain a phandle to the infracfg controller
- clock, clock-names: clocks according to the common clock binding.
- The clocks needed "mm", "mfg", "venc" and "venc_lt".
- These are the clocks which hardware needs to be enabled
- before enabling certain power domains.
