* regulator: Add support for RICOH PMIC RC5T583 regulatorLaxman Dewangan2012-04-044-0/+407
| | | | | | | | | | | | The RC5T583 PMIC from RICOH consists of 4 DCDC and 10 LDOs. This driver supports the control of different regulator output through regulator interface. This driver depends on MFD driver of RC5T583 and uses mfd rc5t583 apis to communicate to device for accessing different device's registers.

* regulator: fixed: Support for open drain gpio pinLaxman Dewangan2012-04-032-12/+18
| | | | | | | | | | | | | | | | | Adding flag on fixed regulator board configuration structure to specify whether gpio is open drain type or not. Passing this information to gpio library when requesting gpio so that gpio driver can set the pin state accordingly, for open drain type: - Pin can be set HIGH as setting as input, PULL UP on pin make this as HIGH. - Pin can be set LOW as setting it as output and drive to LOW. The non-open drain pin can be set HIGH/LOW by setting it to output and driving it to HIGH/LOW.

* regulator: Add support for tps62362 and tps62363 in tps62360-regulator driverAxel Lin2012-04-032-10/+24
| | | | | | | | | | | | According to the datasheet[1], tps62360 is register compatible with tps62362. tps62361B is register compatible with tps62363.

* regulator: Add missing n_voltages setting for max8925Axel Lin2012-04-031-10/+5
| | | | | | | | | | The n_voltages are the same for all regulators: (max - min / step) + 1 == 64. The vol_shift is always 0, and the vol_nbits is always the same as n_voltages setting. Thus we can remove vol_shitf and vol_nbits fields from struct max8925_regulator_info. Signed-off-by: Axel Lin <axel.lin@gmail.com> Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com>

| | | | | | | | | | | | | | | | | | | | | | Integer division may truncate the result. Current code shows changing current is 0mA when selector is 1 ... 8. For example: selector = 1 ad5398_calc_current returns 117, debug message shows 117/1000 = 0mA selector = 2 ad5398_calc_current returns 234, debug message shows 234/1000 = 0mA selector = 3 ad5398_calc_current returns 351, debug message shows 351/1000 = 0mA ............ selector = 8 ad5398_calc_current returns 937, debug message shows 937/1000 = 0mA Show the changing current in uA makes it easier for debugging.

| | | | | | | | | | | | | | | | | | In current implementation, da9052_ldo_ops and da9052_ldo5_6_ops are very similar, only the set_voltage is slightly different. da9052_buckperi_ops and da9052_dcdc_ops are also similar. This patch adds da9052_regulator_set_voltage for the set_voltage callback used by all LDOs and DCDCs. Rework da9052_get_regulator_voltage_sel and da9052_set_dcdc_voltage to make it possible to be shared by all DCDCs. Rework da9052_list_voltage to make it to be shared by all DCDCs and LDOs. Then we can remove da9052_ldo5_6_ops and da9052_buckperi_ops. We can also remove DA9052_LDO5_6 and DA9052_BUCKPERI macros which is not used now.
