Merge tag 'regulator-v4.16' of git://git./linux/kernel/git/broonie/regulator

Pull regulator updates from Mark Brown:
 "This is a quiet release in terms of code volume but a fairly big one
  in terms of framework changes - we've got one long awaited feature in
  the form of runtime configuration of suspend and the start of coupled
  regulator support too:

   - Support for modifying the voltage and enable configuration devices
     will have in suspend, contributed by Chunyan Zhang.

   - Support for the Spreadtrum SC2731, contributed by Erick Chen.

   - The start of changes to support coupled regulators from Maciej
     Purski, the rest of the series should arrive for v4.17"
