Merge tag 'regulator-v4.12' of git://git.kernel.org/pub/scm/linux/kernel/git/broonie/regulator

Pull regulator updates from Mark Brown:
 "Quite a lot going on with the regulator API for this release, much
  more in the core than in the drivers for a change:

   - Fixes for voltage change propagation through dumb power switches.

   - A notification when regulators are enabled.

   - A new settling time property for regulators where the time taken to
     move to a new voltage is not related to the size of the change.

   - Some reorganization of the Arizona drivers in preparation for
     sharing the code with the next generation devices they've been
     integrated with.

   - Support for newer Freescale chips in the Anatop regulator.

   - A new driver for voltage controlled regulators to cope with some
     exciting ChromeOS hardware designs.

   - Support for Rohm BD9571MWV-M and TI TPS65132"
