2012-06-17regulator: ab8500: Remove min_uV and max_uV from struct ab8500_regulator_infoAxel Lin
The min_uV and max_uV are not really used in the code and misleading because the min_uV and max_uV settings does not match the value in the voltage table. For example, we have static const unsigned int ldo_vaux3_voltages[] = { 1200000, 1500000, 1800000, 2100000, 2500000, 2750000, 2790000, 2910000, }; With below min_uV/max_uV settings for AB8500_LDO_AUX3. .min_uV = 1100000, .max_uV = 3300000, The min_uV/max_uV for AB8500_LDO_AUX3 seems copy-paste from AB8500_LDO_AUX2 and is wrong.

ab8500_regulator_fixed_ops Also removes set_voltage_time_sel callback from ab8500_regulator_fixed_ops because the voltage won't change. ( And ab8500_regulator_fixed_ops does not implement get_voltage_sel so set_voltage_time_sel won't be called ) Signed-off-by: Axel Lin <axel.lin@gmail.com> Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com>

2012-06-17regulator: wm8350: Reuse map_voltage() to get selector of a given uVAxel Lin
Reuse map_voltage() to get the selector of a given uV. Then we can remove wm8350_ldo_mvolts_to_val() and wm8350_dcdc_mvolts_to_val(). Also remove unused wm8350_dcdc_val_to_mvolts() function. Signed-off-by: Axel Lin <axel.lin@gmail.com> Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com>

verify selected voltage Call wm8350_ldo_list_voltage() instead of open code to verify selected voltage falls within specified range. Use wm8350_ldo_list_voltage() here is less error prone. wm8350_ldo_val_to_mvolts() is only used in wm8350_ldo_list_voltage now, so remove it and move the implementation to wm8350_ldo_list_voltage(). This patch also include below small changes in wm8350_ldo_map_voltage: 1. wm8350_ldo_map_voltage() returns selector, thus rename variable mV to sel. 2. Use DIV_ROUND_UP macro to calculate selector.

2012-06-13regulator: tps65217: Convert to regulator_[is_enabled|get_voltage_sel]_regmapAxel Lin
This patch converts .is_enabled and .get_voltage_sel to regulator_is_enabled_regmap and regulator_get_voltage_sel_regmap. For .enable, .disable, and .set_voltage_sel, the write protect level is either 1 or 2. So we cannot use regulator_[enable|disable|set_voltage_sel]_regmap. Now we store the enable reg/mask and vsel reg/mask in regulator_desc, so we can remove enable_mask, set_vout_reg, and set_vout_mask from struct tps_info.

2012-06-08regulator: core: Handle fixed voltage in map_voltage_linearAxel Lin
Fixed voltage is a kind of linear mapping where n_voltages is 1. This change allows [list|map]_voltage_linear to be used for fixed voltage. For fixed voltage, n_voltages is 1 and the only valid selector is 0. Thus we actually don't care the uV_step setting.
