Merge tag 'regulator-v5.15' of git://git.kernel.org/pub/scm/linux/kernel/git/broonie/regulator

Pull regulator updates from Mark Brown:
 "A very quiet releases, some fixes and cleanups but not really that
  many of them. There were a couple of new driver specific pieces:

   - Support for controlling the over/under voltage protection on
     BD718xx devices

   - New drivers for Richtek RTQ2134, and RTQ6752"
