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. * tag 'regulator-3.7' of git://git.kernel.org/pub/scm/linux/kernel/git/broonie/regulator: (71 commits) regulator: arizona-ldo: Remove top voltage regulator: tps6586x: remove regulator-compatible from DT docs regulator: tps65217.txt: remove regulator-compatible from DT docs regulator: deprecate regulator-compatible DT property regulator: fan53555: remove vsel_max not used regulator: aat2870: Don't explicitly initialise the first field extcon: arizona: Use bypass mode for MICVDD regulator: wm831x-ldo: Add bypass support regulator: arizona-micsupp: Support get/set bypass regulator: arizona-ldo: Support get/set bypass regulator: core: Provide regmap get/set bypass operations regulator: core: Support bypass mode regulator: Fairchild fan53555 support regulator: twl: Remove another unused variable warning regulator: core: Try using the parent device for the default regmap regulator: core: Fast path non-deferred disables regulator: core: Report microvolts in sysfs even with only list_voltage() regulator: tps6586x: add support for SYS rail regulator: lp872x: remove unnecessary function regulator: lp872x: fix NULL pointer access problem ...
