I would suggest clock-names and description for it.

Shouldn't these be regulators? The power rails are input to the MCU,
correct?
The properties should be something like:
vdds-supply
vddr-supply
dcoupl-supply ? (not sure what dcoupl is, but description should provide
that info).
the gpio controls for those can be modelled by regulator-gpio ?
