Merge tag 'regulator-v3.17' of git://git.kernel.org/pub/scm/linux/kernel/git/broonie/regulator

Pull regulator updates from Mark Brown:
 "A couple of nice new features this month, the ability to map
  regulators in order to allow voltage control by external coprocessors
  is something people have been asking for for a long time.

   - improved support for switch only "regulators", allowing current
     state to be read from the parent regulator but no setting.

   - support for obtaining the register access method used to set
     voltages, for use in systems which can offload control of this to a
     coprocessor (typically for DVFS).

   - support for Active-Semi AC8846, Dialog DA9211 and Texas Instruments
     TPS65917"
