REGULATOR_SET_CURREN(9) API reference REGULATOR_SET_CURREN(9)NAME
regulator_set_current_limit - set regulator output current limit
SYNOPSIS
int regulator_set_current_limit(struct regulator * regulator, int min_uA, int max_uA);
ARGUMENTS
regulator
regulator source
min_uA
Minimum supported current in uA
max_uA
Maximum supported current in uA
DESCRIPTION
Sets current sink to the desired output current. This can be set during any regulator state. IOW, regulator can be disabled or enabled.
If the regulator is enabled then the current will change to the new value immediately otherwise if the regulator is disabled the regulator
will output at the new current when enabled.
NOTE
Regulator system constraints must be set for this regulator before calling this function otherwise this call will fail.

MEMBERS
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.
DESCRIPTION
This struct describes regulator operations which can be implemented by regulator chip drivers.
