regulator: TPS65910: Fix VDD1/2 voltage selector count
Count of selector voltage is required for regulator_set_voltage to work via set_voltage_sel. VDD1/2 currently have it as zero, so regulator_set_voltage won't work for VDD1/2. Update count (n_voltages) for VDD1/2. Output Voltage = (step value * 12.5 mV + 562.5 mV) * gain With above expr, number of voltages that can be selected is step value count * gain count constant for gain count will be called VDD1_2_NUM_VOLT_COARSE existing constant for step value count is VDD1_2_NUM_VOLTS, use VDD1_2_NUM_VOLT_FINE instead to make clear that step value is not the only component in deciding selectable voltage count Signed-off-by: Afzal Mohammed <afzal@ti.com> Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com>
