* regulator: max77686: Initialise rmatch.of_node to NULL.Yadwinder Singh Brar2012-07-061-0/+1
| | | | | | | | Now of_regulator_match() returns without finding the match if match->of_node is not NULL. Signed-off-by: Yadwinder Singh Brar <yadi.brar@samsung.com> Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com>
* regulator: max77686: Add device tree support.Yadwinder Singh Brar2012-07-051-1/+57
| | | | | | | | This patch device tree support for regulator driver. It uses the parent (mfd's) DT node to parse the regulator data for max77686. Signed-off-by: Yadwinder Singh Brar <yadi.brar@samsung.com> Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com>
* regulator: max77686: Implement .set_ramp_delay() callbackYadwinder Singh Brar2012-06-201-8/+29
| | | | | | | | | | | | This patch implements the .set_ramp_delay callback to set the ramp_delay on hardware for BUCK2/3/4 if ramp_delay is set in regulator constraints. This patch also do some cleaning work for unrequired members of struct max77686_data.

* regulator: max77686: Convert driver to use regulator_set_voltage_time_sel.Yadwinder Singh Brar2012-06-191-33/+9
| | | | | | | | | | This patch converts the driver to use regulator_set_voltage_time_sel() as .set_voltage_time_sel() callback. It also sets ramp_delay as 100000 uV/us for LDOs & normal BUCKs and 27500 uV/us(default/reset value) for BUCKs[2/3/4] in regulator_desc[].

* regulator: max77686: Fix the delay time for set_voltage_time_selAxel Lin2012-06-111-2/+2
| | | | | | | | | | rdev->desc->uV_step * abs(new_selector - old_selector) returns uV. The unit of ramp_rate is mV/us. Thus 1000 should be multiplied.

* regulator: max77686: Check pdata->num_regulators earlierAxel Lin2012-06-111-24/+19
| | | | | | | | | | If this driver only works when pdata->num_regulators == MAX77686_REGULATORS, let's check it earlier. Also remove unused num_regulators from struct max77686_data. Signed-off-by: Axel Lin <axel.lin@gmail.com> Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com>

* regulator: max77686: Use regulator_map_voltage_linear for simple linear mappingsAxel Lin2012-06-031-0/+2
| | | | | | | | | Both max77686_ops and max77686_buck_dvs_ops use simple linear voltage maps. Thus use regulator_map_voltage_linear is more efficient than using the defult regulator_map_voltage_iterate.

* regulator: MAX77686: Add Maxim 77686 regulator driverJonghwa Lee2012-06-031-0/+337
Add driver for support max77686 regulator. MAX77686 provides LDOs[1~26] and BUCKs[1~9]. It support to set or get the volatege of regulator on max77686 chip with using regmap.
