These compatibles cannot be alone.
You mean we would need something like "mediatek,scpsys" as dummy compatible
that's not bound to any driver?

If it is simple MFD, then probably it is not a power domain provider.

The SCPSYS IP block of MediaTek SoCs group several functionality, one is the
power domain controller. Others are not yet implemented, but defining the scpsys
as a MFD will give us the possibility to do so in the future.
