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."
