Merge tag 'regulator-v5.0' of git://git.kernel.org/pub/scm/linux/kernel/git/broonie/regulator

Pull regulator updates from Mark Brown:
 "The biggest chunk of the regulator changes for this release outside of
  the new drivers is the conversion of the fixed regulator to use the
  GPIO descriptor API, there's a small addition to the GPIO API plus a
  bunch of updates to board files to implement it. This is some really
  welcome work from Linus Walleij that's had a bunch of review and has
  been sitting in -next for a while so I'm fairly happy there's no major
  issues.

   - Helpers for overlapping linear ranges.

   - Display opmode and consumer requested load in the regualtor_summary
     file in debugfs, plus a fix there.

   - Support for the fun and entertaining power off mechanism that the
     pfuze100 hardware implements.

   - Conversion of the fixed regulator API to use GPIO descriptors,
     including pulling in a bunch of patches to a bunch of board files.

   - New drivers for Cirrus Logic Lochnagar, Qualcomm PMS405, Rohm
     BD71847, ST PMIC1, and TI LM363x devices"
