* regulator: fixed/gpio: Pull inversion/OD into gpiolibLinus Walleij2019-02-061-1/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This pushes the handling of inversion semantics and open drain settings to the GPIO descriptor and gpiolib. All affected board files are also augmented. This is especially nice since we don't have to have any confusing flags passed around to the left and right littering the fixed and GPIO regulator drivers and the regulator core. It is all just very straight-forward: the core asks the GPIO line to be asserted or deasserted and gpiolib deals with the rest depending on how the platform is configured: if the line is active low, it deals with that, if the line is open drain, it deals with that too.

* regulator: da9055: Pass descriptor instead of GPIO numberLinus Walleij2018-02-161-2/+2
| | | | | | | | | | | When setting up a fixed regulator on the DA9055, pass a descriptor instead of a global GPIO number. This facility is not used in the kernel so we can easily just say that this should be a descriptor if/when put to use.

This change removes the use of __devinit, __devexit_p, __devinitdata, __devinitconst, and __devexit from these drivers. Based on patches originally written by Bill Pemberton, but redone by me in order to handle some of the coding style issues better, by hand.

For current regulators the maximum in the given range should be selected instead.

[1] https://lkml.org/lkml/2012/8/5/162 [2] https://lkml.org/lkml/2012/8/6/183 This patch also ensures da9055_buck_set_current_limit return -EINVAL when the supported current limit does not meet the request range.

* regulator: da9055: Properly handle voltage range that doesn't start with 0 ↵Axel Lin2012-11-211-30/+50
| | | | | | | | | | | | | | | | | | | | | offset This patch implements map_voltage and list_voltage callbacks to properly handle the case voltage range that doesn't start with 0 offset. Now we adjust the selector in map_voltage() before calling set_voltage_sel(). And return 0 in list_voltage() for invalid selectors. With above change, we can remove da9055_regulator_set_voltage_bits function. One tricky part is that we need adding voffset to n_voltages. Although for the cases "selector < voffset" are invalid, we need add voffset to n_voltage so regulator_list_voltage() won't fail while checking the boundary for selector before calling list_voltage callback.

This is the Regulator patch for the DA9055 PMIC and has got dependency on the DA9055 MFD core. This patch support all of the DA9055 regulators. The output voltages are fully programmable through I2C interface only. The platform data with regulation constraints is passed down from the board to the regulator. This patch is functionaly tested on SMDK6410 board. DA9055 Evaluation board was connected to the SMDK6410 board.
