Merge tag 'regulator-v5.19' of git://git.kernel.org/pub/scm/linux/kernel/git/broonie/regulator

Pull regulator updates from Mark Brown:
 "This is mostly a drivers update including a couple of new drivers but
  we do have some fixes and improvements to the core as well.

   - Make sure we don't log spuriously about uncontrollable regulators.

   - Don't use delays when we should use sleeps for regulators with
     larger ramp times.

   - Support for MediaTek MT6358 and MT6366, Richtek RT5759 and Silicon
     Mitus SM5703"
