Merge tag 'regulator-v4.18' of git://git.kernel.org/pub/scm/linux/kernel/git/broonie/regulator

Pull regulator updates from Mark Brown:
 "Quite a lot of core work this time around, though not 100% successful.

  We gained support for runtime mode changes thanks to David Collins and
  improved support for write only regulators (ones where we can't read
  back the configuration) from Douglas Anderson.

  There's been quite a bit of work from Linus Walleij on converting from
  specfying GPIOs by numbers to descriptors. Sadly the testing turned
  out to be less good than we had hoped and so a lot of this had to be
  reverted.

  We also have the start of updates to use coupled regulators from
  Maciej Purski, unfortunately there are further problems there so the
  last couple of patches have been reverted.

  We also have new drivers for BD71837 and SY8106A devices, SAW
  regulators on Qualcomm SPMI and dropped support for some preproduction
  chips that never made it to market from the AB8500 driver"
