Merge tag 'regulator-v6.16' of git://git.kernel.org/pub/scm/linux/kernel/git/broonie/regulator

Pull regulator updates from Mark Brown:
 "This is a very quiet release, there was no work on the core and a good
  chunk of the updates were the result of conversions to use newer GPIO
  APIs.

  We did gain support for Analog ADP5055 and TI TPS65214 devices, and
  there's a new restart handler for the PCA9450 which allows devices
  using it to be properly power cycled on reboot, but otherwise it's
  minor fixes and API updates"
