Merge tag 'regulator-3.5' of git://git.kernel.org/pub/scm/linux/kernel/git/broonie/regulator
Pull regulator updates from Mark Brown: "The major thing here is the addition of some helpers to factor code out of drivers, making a fair proportion of regulators much more just data rather than code which is nice. - Helpers in the core for regulators using regmap, providing generic implementations of the enable and voltage selection operations which just need data to describe them in the drivers. - Split out voltage mapping and voltage setting, allowing many more drivers to take advantage of the infrastructure for selectors. - Loads and loads of cleanups from Axel Lin once again, including many changes to take advantage of the above new framework features - New drivers for Ricoh RC5T583, TI TPS62362, TI TPS62363, TI TPS65913, TI TWL6035 and TI TWL6037. Some of the registration changes to support the core refactoring caused so many conflicts that eventually topic branches were abandoned for this release." * tag 'regulator-3.5' of git://git.kernel.org/pub/scm/linux/kernel/git/broonie/regulator: (227 commits) regulator: tps65910: use of_node of matched regulator being register regulator: tps65910: dt: support when "regulators" node found regulator: tps65910: add error message in case of failure regulator: tps62360: dt: initialize of_node param for regulator register. regulator: tps65910: use devm_* for memory allocation regulator: tps65910: use small letter for regulator names mfd: tpx6586x: Depend on regulator regulator: regulator for Palmas Kconfig regulator: regulator driver for Palmas series chips regulator: Enable Device Tree for the db8500-prcmu regulator driver regulator: db8500-prcmu: Separate regulator registration from probe regulator: ab3100: Use regulator_map_voltage_iterate() regulator: tps65217: Convert to set_voltage_sel and map_voltage regulator: Enable the ab8500 for Device Tree regulator: ab8500: Split up probe() into manageable pieces regulator: max8925: Remove check_range function and max_uV from struct rc5t583_regulator_info regulator: max8649: Remove unused check_range() function regulator: rc5t583: Remove max_uV from struct rc5t583_regulator_info regulator: da9052: Convert to set_voltage_sel and map_voltage regulator: max8952: Use devm_kzalloc ...
