REGULATOR_SET_VOLTAG(9) API reference REGULATOR_SET_VOLTAG(9)
NAME
regulator_set_voltage - set regulator output voltage
SYNOPSIS
int regulator_set_voltage(struct regulator * regulator, int min_uV, int max_uV);
ARGUMENTS
regulator
regulator source
min_uV
Minimum required voltage in uV
max_uV
Maximum acceptable voltage in uV
DESCRIPTION
Sets a voltage regulator to the desired output voltage. This can be set during any regulator state. IOW, regulator can be disabled or
enabled.
If the regulator is enabled then the voltage will change to the new value immediately otherwise if the regulator is disabled the regulator
will output at the new voltage when enabled.
NOTE
If the regulator is shared between several devices then the lowest request voltage that meets the system constraints will be used.
Regulator system constraints must be set for this regulator before calling this function otherwise this call will fail.
