Merge tag 'regulator-v7.1' of git://git.kernel.org/pub/scm/linux/kernel/git/broonie/regulator

Pull regulator updates from Mark Brown:
 "This has been a very quiet update for the regulator API, the bulk of
  the diffstat is DT binding conversions and the most promient series in
  the changelog is Johan Hovold cleaning up some leaks of OF nodes. For
  some reason we have had several different people sending improvements
  to better describe the parent supplies for existing regulators, these
  look to be independent efforts.

  The only new hardware support is for some Motorola custom varints of
  cpcap"
