This patch adds rpm node to apq8064 dt as rpm would be used by other devices for regulator support. Also adds all the regulators in the rpm.
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.
