Add binding for the Qualcomm Resource Power Manager (RPM) found in 8660, 8960 and 8064 based devices. Signed-off-by: Bjorn Andersson <bjorn.andersson@sonymobile.com> --- Removed regulator definition from this patch, as these needs more discussion to be able to implement SoC assisted power save features of the Qualcomm platforms.
