Merge tag 'regulator-v4.3' of git://git.kernel.org/pub/scm/linux/kernel/git/broonie/regulator
Pull regulator updates from Mark Brown: "The biggest changes in the core this time around have been some refactorings that move us towards being able to drop the list of regulators maintained by the core and instead just use the driver model list maintained for the class devices for regulators which will make the code smaller and avoid some potential bugs. Otherwise another fairly quiet release for the regulator API, highlights include: - a new API for setting voltages based on a minimum, target, maximum triplet - support for continuous voltage ranges rather than tables of explicit steps in the PWM regulator, requiring less explicit configuration - new driver support for Dialog DA9215, Maxim 77843, Mediatek MT6311 and Qualcomm RPM" * tag 'regulator-v4.3' of git://git.kernel.org/pub/scm/linux/kernel/git/broonie/regulator: (70 commits) regulator: mt6311: fix platform_no_drv_owner.cocci warnings regulator: ltc3589: Remove unnecessary MODULE_ALIAS() regulator: ad5398: Remove unnecessary MODULE_ALIAS() regulator: pfuze100: Remove unnecessary MODULE_ALIAS() regulator: core: use debug level print in regulator_check_drms regulator: lp872x: handle error case regulator: lp872x: use the private data instead of updating I2C device platform data regulator: isl9305: Export OF module alias information regulators: max77693: register driver earlier to avoid deferred probe regulator: qcom_smd: Set n_voltages for pm8941_lnldo regulator: core: Use IS_ERR_OR_NULL() regulator: core: Define regulator_set_voltage_triplet() regulator: Regulator driver for the Qualcomm RPM regulator: pbias: Fix broken pbias disable functionality regulator: core: Spelling fix regulator: core: Use class device list for regulator_list in late init regulator: core: Move more deallocation into class unregister regulator: core: Reduce rdev locking region when releasing regulator Input: Remove the max77843 haptic driver Input: max77693: Add support for Maxim 77843 ...
