Hmm, probably all that can be solved with the new OPP bindings where
we can have support for multiple regulator or clock sources to the CPU.
@Pi-cheng: How are you going to pass voltages for both the regulators
as OPPs today only support a single regulator, in case you have to write
your own driver.
