* regulator: Remove unneeded include of linux/delay.h from regulator driversAxel Lin2012-04-231-1/+0
| | | | | | | | | | | | | All the drivers that need delay for the regulator voltage output voltage to stabilize after being enabled or after being set to a new value has been converted to implement enable_time and set_voltage_time_sel callbacks. Then regulator core will take care of the necessary delay. For the drivers that don't need the delay, don't need to include linux/delay.h. This patch removes the unneeded include of linux/delay.h in regulator drivers. Signed-off-by: Axel Lin <axel.lin@gmail.com> Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com>

* regulator: core: Use a struct to pass in regulator runtime configurationMark Brown2012-04-091-2/+7
| | | | | | | | | | | | | | 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.

* regulator: Use tps65912_get_voltage for both DCDCs and LDOsAxel Lin2012-04-011-18/+3
| | | | | | | | Now tps65912_get_voltage_dcdc and tps65912_get_voltage_ldo has exactly the same implementation. We can merge them to tps65912_get_voltage function. Signed-off-by: Axel Lin <axel.lin@gmail.com> Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com>
* regulator: Implement tps65912_list_voltage to be shared by both DCDCs and LDOsAxel Lin2012-04-011-16/+7
| | | | | | | | | Merge tps65912_list_voltage_dcdc and tps65912_list_voltage_ldo to tps65912_list_voltage. This change does not add too much complexity in tps65912_list_voltage function. Signed-off-by: Axel Lin <axel.lin@gmail.com> Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com>

| | | | | | | | | | | | 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.

* regulator: tps65912: Use simple equations to get register addressAxel Lin2012-03-131-144/+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.

* regulator: pass additional of_node to regulator_register()Rajendra Nayak2011-11-231-1/+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.

* regulator: tps65912: Remove unused define of TPS65912_MAX_REG_IDAxel Lin2011-08-081-2/+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.

* tps65912: add regulator driverMargarita Olaya2011-07-311-0/+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.
