Merge tag 'regulator-v3.17' of git://git.kernel.org/pub/scm/linux/kernel/git/broonie/regulator
Pull regulator updates from Mark Brown: "A couple of nice new features this month, the ability to map regulators in order to allow voltage control by external coprocessors is something people have been asking for for a long time. - improved support for switch only "regulators", allowing current state to be read from the parent regulator but no setting. - support for obtaining the register access method used to set voltages, for use in systems which can offload control of this to a coprocessor (typically for DVFS). - support for Active-Semi AC8846, Dialog DA9211 and Texas Instruments TPS65917" * tag 'regulator-v3.17' of git://git.kernel.org/pub/scm/linux/kernel/git/broonie/regulator: (58 commits) regulator: act8865: fix build when OF is not enabled regulator: act8865: add act8846 to DT binding documentation regulator: act8865: add support for act8846 regulator: act8865: prepare support for other act88xx devices regulator: act8865: set correct number of regulators in pdata regulator: act8865: Remove error variable in act8865_pmic_probe regulator: act8865: fix parsing of platform data regulator: tps65090: Set voltage for fixed regulators regulator: core: Allow to get voltage count and list from parent regulator: core: Get voltage from parent if not available regulator: Add missing statics and inlines for stub functions regulator: lp872x: Don't set constraints within the regulator driver regmap: Fix return code for stub regmap_get_device() regulator: s2mps11: Update module description and Kconfig to add S2MPU02 support regulator: Add helpers for low-level register access regmap: Allow regmap_get_device() to be used by modules regmap: Add regmap_get_device regulator: da9211: Remove unnecessary devm_regulator_unregister() calls regulator: Add DT bindings for tps65218 PMIC regulators. regulator: da9211: new regulator driver ...
