I think it shouldn't include the regulator part of things.

We should just query this information from the regulator subsystem
(there's hooks but currently nothing implements them). The regulators
can define their own bindings if they need to read it from device tree,
most of them should be able to do this as a function of knowing about
the device. None of this is specific to cpufreq so cpufreq shouldn't
have to define its own support for this.
