Merge tag 'regulator-3.4' of git://git.kernel.org/pub/scm/linux/kernel/git/broonie/regulator
Pull regulator updates for 3.4 from Mark Brown: "This has been a fairly quiet release from a regulator point of view, the only real framework features added were devm support and a convenience helper for setting up fixed voltage regulators. We also added a couple of drivers (but will drop the BQ240022 driver via the arm-soc tree as it's been replaced by the more generic gpio-regulator driver) and Axel Lin continued his relentless and generally awesome stream of fixes and cleanups." * tag 'regulator-3.4' of git://git.kernel.org/pub/scm/linux/kernel/git/broonie/regulator: (93 commits) regulator: Fix up a confusing dev_warn when DT lookup fails regulator: Convert tps6507x to set_voltage_sel regulator: Refactor tps6507x to use one tps6507x_pmic_ops for all LDOs and DCDCs regulator: Make s5m8767_get_voltage_register always return correct register regulator: s5m8767: Check pdata->buck[2|3|4]_gpiodvs earlier regulator: tps65910: Provide settling time for DCDC voltage change regulator: Add Anatop regulator driver regulator: Simplify implementation of tps65912_get_voltage_dcdc regulator: Use tps65912_set_voltage_sel for both DCDCx and LDOx regulator: tps65910: Provide settling time for enabling rails regulator: max8925: Use DIV_ROUND_UP macro regulator: tps65912: Use simple equations to get register address regulator: Fix the logic of tps65910_get_mode regulator: Merge tps65217_pmic_ldo234_ops and tps65217_pmic_dcdc_ops to tps65217_pmic_ops regulator: Use DIV_ROUND_CLOSEST in wm8350_isink_get_current regulator: Use array to store dcdc_range settings for tps65912 regulator: Rename s5m8767_convert_voltage to s5m8767_convert_voltage_to_sel regulator: tps6524x: Remove unneeded comment for N_REGULATORS regulator: Rename set_voltage_sel callback function name to *_sel regulator: Fix s5m8767_set_voltage_time_sel calculation value ...
