Some comments on the compatibles, based on rpm-regulator-8960 msm-3.4.
After giving this some more thought I think it would be good to defer the
voltage definition to the dts files, at least for the ldos (as these are being
re-purposed).
That way the dts implementor will be the one frying their components and not us
because some default value kicking in because someone miss-spelled or forgot to
override a certain voltage.
