2012-06-08regulator: da903x: Don't read/write to DA9030_INVAL/DA9034_INVAL addressAxel Lin
For fixed voltage, DA9030_LDO13 and DA9034_LDO5, the info->vol_reg is DA9030_INVAL/DA9034_INVAL. It does not make sense to read/write to DA9030_INVAL/DA9034_INVAL address. Signed-off-by: Axel Lin <axel.lin@gmail.com> Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com>
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>

2012-04-09regulator: core: Use a struct to pass in regulator runtime configurationMark Brown
Rather than adding new arguments to regulator_register() every time we want to add a new bit of dynamic information at runtime change the function to take these via a struct. By doing this we avoid needing to do further changes like the recent addition of device tree support which required each regulator driver to be updated to take an additional parameter. The regulator_desc which should (mostly) be static data is still passed separately as most drivers are able to configure this statically at build time.

2011-11-23regulator: pass additional of_node to regulator_register()Rajendra Nayak
With device tree support for regulators, its needed that the regulator_dev->dev device has the right of_node attached. To be able to do this add an additional parameter to the regulator_register() api, wherein the dt-adapted driver can then pass this additional info onto the regulator core.

2011-10-31regulator: Add module.h to drivers/regulator users as requiredPaul Gortmaker
Another group of drivers that are taking advantage of the implicit presence of module.h -- and will break when we pull the carpet out from under them during a cleanup. Fix 'em now. Signed-off-by: Paul Gortmaker <paul.gortmaker@windriver.com>
2011-01-12regulator: Report actual configured voltage to set_voltage()Mark Brown
Change the interface used by set_voltage() to report the selected value to the regulator core in terms of a selector used by list_voltage(). This allows the regulator core to know the voltage that was chosen without having to do an explict get_voltage(), which would be much more expensive as it will generally access hardware.

2009-09-22regulator: replace ADTV1 register by ADTV2 in da903xHaojian Zhuang
In PXA3xx SoC family, V_CORE power doamin is supplied by BUCK1 that is controller by ADTV1 or ADTV2 register. By default, v1 and v2 has the same copy. If v1 or v2 is updated, the last value that is written to either register takes effect. It means that v1 and v2 has different copy. And the actual voltage output is determinated by last update on either register. DA9034/35 is binded with PXA3xx SoC family. While SoC is scaling OP or entering/exiting lower power mode, SoC needs to change voltage of V_CORE power doamin. In order to be efficient, POWER I2C (hardcode) mode could be enabled in SoC. In this mode, SoC will control v2 register directly. In original DA903x driver, software will only read regulator data from v1 register. But SoC controls v2 register directly. It results that v1 and v2 isn't synchronized. Wrong data will be read from v1 register. So access v2 register in da903x driver instead.

2009-06-15regulator: Move regulator drivers to subsys_initcall()Mark Brown
Regulators need to be available early in init in order to allow them to be available for consumers when requested. This is generally done by registering them at subsys_initcall() time but not all regulator drivers have done that. Convert these drivers to do so in order to mimimise future support.
