2012-03-14regulator: Simplify implementation of tps65912_get_voltage_dcdcAxel Lin1-26/+5
Call tps65912_get_sel_register instead of duplicating the same code. Signed-off-by: Axel Lin <axel.lin@gmail.com> Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com>
2012-03-14regulator: Use tps65912_set_voltage_sel for both DCDCx and LDOxAxel Lin1-16/+3
commit 42b5ef "regulator: tps65912: Use simple equations to get register address" uses tps65912_get_sel_register to replace tps65912_get_dcdc_sel_register and tps65912_get_ldo_sel_register. Now tps65912_set_voltage_dcdc_sel and tps65912_set_voltage_ldo_sel has exactly the same implementation. Merge them to tps65912_set_voltage_sel function.

2012-03-14regulator: tps65912: Use simple equations to get register addressAxel Lin1-144/+18
The address of ctrl and sel registers can be calculated by simple equations. This patch simplifies the implementation in tps65912_get_ctrl_register and implements tps65912_get_sel_register to replace tps65912_get_dcdc_sel_register and tps65912_get_ldo_sel_register.

2012-03-12regulator: Use array to store dcdc_range settings for tps65912Axel Lin1-50/+20
Then we can use the regulator id as array index to access the array. This change makes the code simpler. Signed-off-by: Axel Lin <axel.lin@gmail.com> Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com>
2012-03-12regulator: Rename set_voltage_sel callback function name to *_selAxel Lin1-6/+6

2012-03-12regulator: Simplify the implementation of tps65912_get_voltage_dcdcAxel Lin1-67/+45

2011-11-23regulator: pass additional of_node to regulator_register()Rajendra Nayak1-1/+1
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.

2011-08-08regulator: tps65912: Remove unused define of TPS65912_MAX_REG_IDAxel Lin1-2/+0
Currently we define TPS65912_MAX_REG_ID as TPS65912_REG_LDO_10, but TPS65912_REG_LDO_10 is not defined at all. ( It looks like a typo of TPS65912_REG_LDO10 ) Currently, TPS65912_MAX_REG_ID is not used in this driver, it is safe to just remove it.

2011-08-01regulator: Storing tps65912 error codes in u8Dan Carpenter1-1/+1
get_ctrl_reg() returns -EINVAL so the error handling won't work here if reg is a u8. Signed-off-by: Dan Carpenter <error27@gmail.com> Signed-off-by: Samuel Ortiz <sameo@linux.intel.com>
2011-08-01tps65912: add regulator driverMargarita Olaya1-0/+800
The tps65912 consist of 4 DCDCs and 10 LDOs. The output voltages can be configured by the SPI or I2C interface, they are meant to supply power to the main processor and other components.
