2012-03-14regulator: Make s5m8767_get_voltage_register always return correct registerAxel Lin1-18/+9
Check s5m8767->buck[2|3|4]_gpiodvs status in s5m8767_get_voltage_register and return correct register accordingly. Signed-off-by: Axel Lin <axel.lin@gmail.com> Acked-by: Sangbeom Kim <sbkim73@samsung.com> Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com>
2012-03-14regulator: s5m8767: Check pdata->buck[2|3|4]_gpiodvs earlierAxel Lin1-24/+21
If we need to ensure only one of the buck[2|3|4]_gpiodvs can be specificed, check them earlier. Signed-off-by: Axel Lin <axel.lin@gmail.com> Acked-by: Sangbeom Kim <sbkim73@samsung.com> Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com>
2012-03-12regulator: Rename s5m8767_convert_voltage to s5m8767_convert_voltage_to_selAxel Lin1-12/+10
This function finds the smallest voltage that falls within the specified range, and then returns the selector. This rename makes the intention more clear. Also remove unneeded local variables min_vol and max_vol in s5m8767_set_voltage and s5m8767_set_voltage_buck.

2012-03-12regulator: Fix s5m8767_set_voltage_time_sel calculation valueSangbeom Kim1-1/+1
In the s5m8767_set_voltage_time_sel function, divisor unit is wrong. ramp_delay is usec unit. So 1000 should be multiplied. Signed-off-by: Sangbeom Kim <sbkim73@samsung.com> Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com>

2012-03-12regulator: Fix the logic of s5m8767_set_voltage_time_selAxel Lin1-28/+2
This patch includes below fixes: 1. The mask variable is not used at all here, remove it. 2. We already have the new_sel and old_sel, simply returns the delay by: DIV_ROUND_UP(desc->step * (new_sel - old_sel), s5m8767->ramp_delay); Signed-off-by: Axel Lin <axel.lin@gmail.com> Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com>

2012-02-02regulator: Kill s5m8767_get_reg_id functionAxel Lin1-12/+7
Calling s5m8767_get_reg_id() is exactly the same as calling rdev_get_id(). It is pointless to add s5m8767_get_reg_id() function. Use rdev_get_id() directly and remove s5m8767_get_reg_id() function.

2012-01-20regulator: s5m8767: Remove redundant MODULE_ALIASAxel Lin1-1/+0
The MODULE_DEVICE_TABLE will setup the modalias, thus adding a MODULE_ALIAS for an entry already in s5m8767_pmic_id is redundant. Signed-off-by: Axel Lin <axel.lin@gmail.com> Acked-by: Sangbeom Kim <sbkim73@samsung.com> Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com>

2012-01-20regulator: Add S5M8767A regulator driverSangbeom Kim1-0/+834
S5M8767A is a cost-effective PMIC which is designed for mobile applications. It includes high efficient 9 Buck converters, 28 LDOs. Especially, S5M8767A is optimized for Multi-core SOCs. And during DVFS operation, S5M8767A output stable voltage. This patch implement regulator driver for S5M8767A.
