REGULATOR_MAP_VOLTAG(9) 					   API reference					   REGULATOR_MAP_VOLTAG(9)

NAME
regulator_map_voltage_ascend - map_voltage for ascendant voltage list SYNOPSIS
int regulator_map_voltage_ascend(struct regulator_dev * rdev, int min_uV, int max_uV); ARGUMENTS
rdev Regulator to operate on min_uV Lower bound for voltage max_uV Upper bound for voltage DESCRIPTION
Drivers that have ascendant voltage list can use this as their map_voltage operation. AUTHORS

struct_regulator_ops - regulator operations. SYNOPSIS

list_voltage Return one of the supported voltages, in microvolts; zero if the selector indicates a voltage that is unusable on this system; or negative errno. Selectors range from zero to one less than regulator_desc.n_voltages. Voltages may be reported in any order. set_voltage Set the voltage for the regulator within the range specified. The driver should select the voltage closest to min_uV. map_voltage Convert a voltage into a selector set_voltage_sel Set the voltage for the regulator using the specified selector. get_voltage Return the currently configured voltage for the regulator. get_voltage_sel Return the currently configured voltage selector for the regulator. set_current_limit Configure a limit for a current-limited regulator. The driver should select the current closest to max_uA. get_current_limit Get the configured limit for a current-limited regulator. enable Configure the regulator as enabled. disable Configure the regulator as disabled. is_enabled Return 1 if the regulator is enabled, 0 if not. May also return negative errno. set_mode Set the configured operating mode for the regulator. get_mode Get the configured operating mode for the regulator. enable_time Time taken for the regulator voltage output voltage to stabilise after being enabled, in microseconds. set_ramp_delay Set the ramp delay for the regulator. The driver should select ramp delay equal to or less than(closest) ramp_delay. set_voltage_time_sel Time taken for the regulator voltage output voltage to stabilise after being set to a new value, in microseconds. The function provides the from and to voltage selector, the function should return the worst case. get_status Return actual (not as-configured) status of regulator, as a REGULATOR_STATUS value (or negative errno) get_optimum_mode Get the most efficient operating mode for the regulator when running with the specified parameters. set_bypass Set the regulator in bypass mode. get_bypass Get the regulator bypass mode state. set_suspend_voltage Set the voltage for the regulator when the system is suspended. set_suspend_enable Mark the regulator as enabled when the system is suspended. set_suspend_disable Mark the regulator as disabled when the system is suspended. set_suspend_mode Set the operating mode for the regulator when the system is suspended.
