Neither little nor medium need power? Why you do not need to provide all supplies? About the naming, use something matching the devices, e.g. from their datasheet/manual. Best regards, Krzysztof

The performance-controller hardware block on MediaTek SoCs is responsible for controlling the frequency of the CPUs. As such, it needs any CPU regulator to have been configured prior to initializing. Add a phandle in the binding so this dependency can be described. Signed-off-by: Nícolas F. R. A.
