Merge tag 'regulator-v4.13' of git://git.kernel.org/pub/scm/linux/kernel/git/broonie/regulator

Pull regulator updates from Mark Brown:
 "A quiet release for the regulator API, a series of fairly small fixes
  plus one new feature and a few new drivers:

   - Support for regulators with different settling times for rising and
     falling voltage changes.

   - New drivers for Allwinner AXP803, HiSilicon HI6421V530 and TI
     LP87565"
