So how do we handle CPUs? cpufreq is one of the most active users of
regulators...
Hmm, never thought of it :(
Maybe I should associate a supply name with all
regulators and then lookup from the global registered
list.

sz< 4? Magic! :)
Its the valid phandle size.
I guess I need a sz != 4

This shouldn't be part of the public API, it should be transparently
handled within the core.
agreed.
