Merge tag 'regulator-3.7' of git://git.kernel.org/pub/scm/linux/kernel/git/broonie/regulator

Pull regulator updates from Mark Brown:
 - Support for putting regulators into bypass mode where they simply
   switch their input to the output (mainly used for low power
   retention).
 - A new API for setting voltages based on a voltage plus tolerance
   rather than an explicit voltage range.
 - Lots of cleanups and API updates from Axel Lin.
 - New driver for MAX8907.
