Merge tag 'regulator-v6.20' of git://git.kernel.org/pub/scm/linux/kernel/git/broonie/regulator

Pull regulator updates from Mark Brown:
 "There's a bunch of new drivers here, plus a lot of hardening for the
  supply resolution code which allow us to support systems where we have
  two PMICs each of which has regulators supplied by the other. This did
  work a long time ago but got broken as part of improved integration
  with the device model, it's fairly rare so nobody noticed.

   - Improvements for supply handling from André Draszik to allow
     systems with two PMICs with supply/consumer relationships in both
     directions to instantiate.

   - New drivers for Maxim MAX776750, Realtek RT8902, Samsung S2MPG11,
     Texas Instuments TPS65185.

  This have also pulls in some MFD updates which are build dependencies
  for the Samsung S2MPG11 support"
