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.
