Merge tag 'regulator-v4.1' of git://git.kernel.org/pub/scm/linux/kernel/git/broonie/regulator

Pull regulator updates from Mark Brown:
 "Another release, another set of regulator updates.  Not much of it is
  showing up in the code yet but there's been a lot of discussion going
  on about how to enhance the regulator API to work better with modern
  SoCs which have a microcontroller sitting between Linux and the
  hardware.

  I'm hopeful that'll start to come through into mainline for v4.2 but
  it's not quite there for v4.1 - what we do have (along with the usual
  small updates is) is:

   - work from Bjorn Andersson on refactoring the configuration of
     regulator loading interfaces to be useful for use with
     microcontrollers, the existing interfaces were never actually
     useful for anything as-is since nobody was willing to put enough
     data into public code.

   - a summary tree display in debugfs from Heiko Stübner.

   - support for act6000 regulators"
