This commit adds support to max77686 regulator driver based on a uclass regulator driver-model api, which provides implementation of all uclass regulator api function calls.
New file: drivers/power/regulator/max77686.c New config: CONFIG_DM_REGULATOR_MAX77686
Signed-off-by: Przemyslaw Marczak p.marczak@samsung.com --- Changes V2: - change debug() to error() - code cleanup - fix data types - ldo/buck state implementation - adjust to new uclass api
Changes V3: - regulator/max77686.c: -- adjust to api changes -- add separeted drivers for buck and ldo -- bind regulators by its compatibles - Kconfig: add regulator max77686 entry --- Makefile | 1 + drivers/power/Kconfig | 8 + drivers/power/Makefile | 1 - drivers/power/regulator/Makefile | 8 + drivers/power/regulator/max77686.c | 876 +++++++++++++++++++++++++++++++++++++ include/power/max77686_pmic.h | 24 +- 6 files changed, 914 insertions(+), 4 deletions(-) create mode 100644 drivers/power/regulator/Makefile create mode 100644 drivers/power/regulator/max77686.c
