2012-05-15regulator: da903x: Kill da903x_[get|set]_[ldo12|ldo14]_voltage_sel() functionsAxel Lin
Now the implementation of da903x_set_voltage_sel, da9030_set_ldo14_voltage_sel, and da9034_set_ldo12_voltage_sel are exactly the same. da903x_get_voltage_sel, da9030_get_ldo14_voltage_sel and da9034_get_ldo12_voltage_sel are exactly the same. So we can use da903x_[get|set]_voltage_sel and kill other functions. Signed-off-by: Axel Lin <axel.lin@gmail.com> Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com>

Change the mechanism of enabling the force PWM mode through regulator set mode. This can be dynamically configured now. In the REGULATOR_MODE_FAST the force PWM is enabled and in REGULATOR_MODE_NORMAL the force PWM is disabled.

2012-05-12regulator: core: Allow drivers to set simple linear voltage maps as dataMark Brown
A lot of regulator hardware maps selectors on to voltages with a simple linear mapping function selector = base + (selector * step size) Provide off the shelf list_voltage() and map_voltage() operations which use new min_uV and uV_step members in the regulator_desc to implement this function.

2012-05-12regulator: core: Allow regulators to provide a voltage to selector mappingMark Brown
In order to allow more drivers to factor things out into data allow drivers to provide a mapping function to convert voltages into selectors. This allows any driver to use set_voltage_sel(). The existing mapping based on iterating over list_voltage() is provided as an operation which can be assigned to the new map_voltage() function though for ease of transition it is treated as the default.

2012-05-10regulator: wm831x: Register all normal regulatorsMark Brown
Register all normal regulators rather than skipping unconfigured ones now that the core can handle regulators without init data. Skip the boost and isink regulators since they are normally controlled by other drivers. Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com>
2012-05-09regulator: twl-regulator: make TWL4030_ALLOW_UNSUPPORTED more configurable.NeilBrown
The regulators in the twl4030 can provide some voltage settings that are not offically supported. These settings are disabled by default, but can be enabled with CONFIG_TWL4030_ALLOW_UNSUPPORTED=y However - that config variable is not mentioned in any Kconfig so cannot be used, and - a global setting is clumsy - a per regulator setting would be better. So define a new 'feature' flag that a board file can set to enable these unsupported volatages for boards which need them. This flag cannot (yet) be set using device-tree.

2012-05-09mfd: twl: define all feature flags in one place.NeilBrown
twl-regulator has a collection of feature flags, some defined in twl-core.c and one defined in i2c/twl.h. This is confusing for anyone adding a new feature flag. So collect them together and place them in twl.h immediately after the structure in which they are initially set.

2012-05-08regulator: tps62360: fix stylistic issue and optimize codeLaxman Dewangan
Fix multiple stylistic issue like: - The print message should be not break into multiple line. - line gap after variable declaration and statement. - checkpatch error. - some typo. Some enhancement on error message printing to print error value also along with proper text. Avoid voltage_base conversion to microvolts every time. Put init functions in init section. Using efficient function inplace of calling multiple function to reduce the code size.
