Merge tag 'regulator-3.5' of git://git.kernel.org/pub/scm/linux/kernel/git/broonie/regulator

Pull regulator updates from Mark Brown:
 "The major thing here is the addition of some helpers to factor code
  out of drivers, making a fair proportion of regulators much more just
  data rather than code which is nice.

  - Helpers in the core for regulators using regmap, providing generic
    implementations of the enable and voltage selection operations which
    just need data to describe them in the drivers.
  - Split out voltage mapping and voltage setting, allowing many more
    drivers to take advantage of the infrastructure for selectors.
  - Loads and loads of cleanups from Axel Lin once again, including many
    changes to take advantage of the above new framework features
  - New drivers for Ricoh RC5T583, TI TPS62362, TI TPS62363, TI
    TPS65913, TI TWL6035 and TI TWL6037.

  Some of the registration changes to support the core refactoring
  caused so many conflicts that eventually topic branches were abandoned
  for this release."
