This patch adds regulator_set_voltage_time_sel(), to move into core, the commonly used code by drivers to provide the .set_voltage_time_sel callback. It will also allow us to configure different ramp delay for different regulators easily. Signed-off-by:

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:

isl_fixed_ops does not implement set_voltage_sel callback, adding map_voltage here is misleading. Signed-off-by:

Also adds tps6586x_ldo0_voltages mapping table for LDO0, so we can remove the hack in tps6586x_list_voltage() and convert it to regulator_list_voltage_table. Signed-off-by:

It's a little bit hard to read that the "else" case means id == PALMAS_REG_SMPS10. if (id != PALMAS_REG_SMPS10){ do something for the cases id != PALMAS_REG_SMPS10; } else { do something for the case id == PALMAS_REG_SMPS10; } This patch changes above syntax to switch statement.

For linear mappings, we can use below equation to get the voltage difference between new_selector and old_selector: abs(new_selector - old_selector) * rdev->desc->uV_step Signed-off-by:

For fixed voltage, DA9030_LDO13 and DA9034_LDO5, the info->vol_reg is DA9030_INVAL/DA9034_INVAL. It does not make sense to read/write to DA9030_INVAL/DA9034_INVAL address. Signed-off-by:

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. Signed-off-by:

The voltage mapping table for LDO2 is exactly the same as VDCDCx. Thus we can use one mapping table for both LDO2 and VDCDCx instead of duplicating the mapping table. Signed-off-by:

The min_uV and max_uV are not used in this driver. For table based voltage mappings, we can get min_uV and max_uV by info->table[0] and info->table[table_len -1]. Thus remove min_uV and max_uV from struct tps_info. Signed-off-by:
