Pull regulator updates from Mark Brown:
 "Aside from a fix for a spurious warning (which caused more problems
  than it fixed in the fixing really) this is all driver updates,
  including new drivers for Dialog PV88060/90 and TI LM363x and TPS65086
  devices.  The qcom_smd driver has had PM8916 and PMA8084 support
  added"

Qualcomm Resource Power Manager (RPM) over SMD

QCOM SMD RPM REGULATOR



This driver is used to interface with the Resource Power Manager (RPM) found in

various Qualcomm platforms. The RPM allows each component in the system to vote

for state of the system resources, such as clocks, regulators and bus

frequencies.

The Qualcomm RPM over SMD regulator is modelled as a subdevice of the RPM.

Because SMD is used as the communication transport mechanism, the RPM resides as

a subnode of the SMD.  As such, the SMD-RPM regulator requires that the SMD and

RPM nodes be present.
