Merge tag 'regulator-v3.15' of git://git.kernel.org/pub/scm/linux/kernel/git/broonie/regulator

Pull regulator updates from Mark Brown:
 "This release has lots and lots of small cleanups and fixes in the
  regulator subsystem, mainly cleaning up some bad patterns that got
  duplicated in DT code, but otherwise very little of note outside of
  the scope of the relevant drivers:

   - Support for configuration of the initial state for gpio regulators
     with multi-voltage support.
   - Support for calling regulator_set_voltage() on fixed regulators.
   - New drivers for Broadcom BCM590xx, Freescale pfuze200, Samsung
     S2MPA01 & S2MPS11/4, some PWM controlled regulators found on some
     ST boards and TI TPS65218"
