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.
