Merge tag 'regulator-3.9' of git://git.kernel.org/pub/scm/linux/kernel/git/broonie/regulator

Pull regulator updates from Mark Brown:
 "A fairly quiet release for the regulator API, the bulk of the changes
  being lots of small cleanups and API updates contributed by Axel Lin
  with just a small set of larger changes:

   - New driver for LP8755

   - DT support for S5M8767, TPS51632, TPS6507x and TPS65090

   - Support for writing a "commit changes" bit in the regmap helper
     functions."
