Merge tag 'regulator-3.6' of git://git.kernel.org/pub/scm/linux/kernel/git/broonie/regulator 

Pull regulator updates from Mark Brown:
 "Lots and lots of fixes from Axel and some others here, plus some
  framework enhancements which continue the theme of factoring code out
  of the drivers and into the core.

   - Initial framework support for GPIO controlled enable signals,
     saving a bunch of code in drivers.
   - Move fixed regulator enable time and voltage mapping table
     specifications to data.
   - Used some of the recent framework enhancements to make voltage
     change notifications more useful, passing the voltage in as an
     argument to the notification.
   - Fixed the pattern used for finding individual regulators on a
     device to not rely on the node name, supporting the use of multiple
     PMICs of the same type in the system.
   - New drivers for Maxim MAX77686, TI LP872x and LP8788, Samsung
     S2MPS11, and Wolfson Arizona microphone supplies and LDOs."
