2018-12-11regulator: max77686: Let core handle GPIO descriptorLinus Walleij1-5/+9
Use the gpiod_get_from_of_node() rather than the devm_* version so that the regulator core can handle the lifecycle of these descriptors. Fix up the errorpath so that we free this descriptor if an error occurs in the callback. Rely on the regulator core to deal with it after this point: a previous patch fixed up the regulator core to properly dispose any GPIO descriptors once you call regulator_register().

2018-11-15regulator: max77686: Pass descriptor instead of GPIO numberLinus Walleij1-7/+12
Instead of passing a global GPIO number, pass a descriptor looked up from the device tree configuration node. Tested on Odroid U3 (with max77686 although not using any GPIOs for regulators, so at least default paths are not broken).

2017-01-31regulator: max77686-regulator: constify regulator_ops structureBhumika Goyal1-4/+4
Declare regulator_ops structure as const as it is only stored in the ops field of a regulator_desc structure. This field is of type const, so regulator_ops structures having this property can be made const too.

2016-04-29regulator: max77686: Configure enable time to properly handle regulator enableKrzysztof Kozlowski1-0/+5
The enable time for buck regulators was not configured but actually is essential: consumers, like usb3503, doing hard reset (regulator off/on) should wait for the regulator to settle. Configure the enable time according to datasheet. Signed-off-by: Krzysztof Kozlowski <k.kozlowski@samsung.com> Signed-off-by: Mark Brown <broonie@kernel.org>
2016-04-06regulator: max77686: Use module_platform_driver() instead subsys initcallJavier Martinez Canillas1-11/+1
The driver's init and exit function don't do anything besides registering and unregistering the platform driver, so the module_platform_driver() macro could just be used instead of having separate functions. Currently the macro is not being used because the driver is initialized at subsys init call level but this isn't necessary since consumer devices are defined in the DT as dependencies so there's no need for init calls order.

2016-02-12regulator: Rename files for max77686 and max77802 driversJavier Martinez Canillas1-0/+570
The max77686 and max77802 regulator drivers are for sub-devices of a MFD driver for some PMIC blocks. But the same object file name (max77686.o) was used for both the common MFD driver and the max77686 regulator one. This confuses kbuild if both drivers are built as module causing the MFD driver to not be copied when installing the modules. Also, max77{686,802} are a quite generic name for MFD subdevices drivers so it is better to rename them to max77{686,802}-regulator like it's the case for most regulator drivers.
