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.
