2015-12-22regulator: da9*: constify regulator_ops structuresJulia Lawall
The regulator_ops structures are never modified, so declare them as const. Done with the help of Coccinelle. Signed-off-by: Julia Lawall <Julia.Lawall@lip6.fr> Signed-off-by: Mark Brown <broonie@kernel.org>

A platform_driver does not need to set an owner, it will be populated by the driver core. Signed-off-by: Wolfram Sang <wsa@the-dreams.de>

2013-01-03Drivers: regulator: remove __dev* attributes.Greg Kroah-Hartman
CONFIG_HOTPLUG is going away as an option. As a result, the __dev* markings need to be removed. 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.

2012-11-27regulator: da9055: Select maximum current in specific range for ↵Axel Lin
set_current_limit Selecting the minimal value is only true for voltage regulators. For current regulators the maximum in the given range should be selected instead. This issue was reported by Heiko Stuebner for gpio-regulator driver [1], and the conclusion is to select the max current for current regulators [2]. [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.

2012-11-21regulator: da9055: Properly handle voltage range that doesn't start with 0 ↵Axel Lin
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.

2012-11-15regulator: DA9055 regulator driverAshish Jangam
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.
