Merge tag 'regulator-3.8' of git://git.kernel.org/pub/scm/linux/kernel/git/broonie/regulator

Pull regulator updates from Mark Brown:
 "A fairly quiet release again, a couple of relatively small new
  features and a bunch of driver specific work including yet more code
  elimination and fixes from Axel Lin.

   - Addidion of linear_min_sel for offsetting linear selectors in the
     helpers.
   - Support for continuous voltage ranges for regulators with extremely
     high resolution.
   - Drivers for AS3711, DA9055, MAX9873, TPS51632, TPS80031 and ARM
     vexpress."

Fix up trivial conflict (due to typo fix) in palmas-regulator.c
