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.

		This will be one of the same strings reported by

		the "state" attribute.



What:		/sys/class/regulator/.../bypass

Date:		September 2012

KernelVersion:	3.7

Contact:	Mark Brown <broonie@opensource.wolfsonmicro.com>

Description:

		Some regulator directories will contain a field called

		bypass.  This indicates if the device is in bypass mode.



		This will be one of the following strings:



		'enabled'

		'disabled'

		'unknown'



		'enabled' means the regulator is in bypass mode.



		'disabled' means that the regulator is regulating.



		'unknown' means software cannot determine the state, or

		the reported state is invalid.
