regulator_set_current_limit - set regulator output current limit

int regulator_set_current_limit(struct regulator *  regulator , int  min_uA , int  max_uA );

regulator
    regulator source

min_uA
    Minimum supported current in uA

max_uA
    Maximum supported current in uA

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.

Regulator system constraints must be set for this regulator before calling this function otherwise this call will fail.
