Merge tag 'regulator-v7.3' of git://git.kernel.org/pub/scm/linux/kernel/git/broonie/regulator

Pull regulator updates from Mark Brown:
 "This is a relatively quiet release for the regulator API, we've had no
  major core work and not really that much driver work either. There's a
  bunch of activity, including several new devices, but nothing hugely
  remarkable here.

   - Reworking of the mode handling in the max14577 driver to fix issues
     with collisions with enables

   - Support for onsemi FAN53555BUC23X, Qualcomm IPQ9650, PM4125 VBUS
     and PM8150B and Unisoc SC2730"
