regulator_set_voltage_time_sel - get raise/fall time

int regulator_set_voltage_time_sel(struct regulator_dev *  rdev , unsigned int  old_selector , unsigned int  new_selector );

rdev
    regulator source device

old_selector
    selector for starting voltage

new_selector
    selector for target voltage

Provided with the starting and target voltage selectors, this function returns time in microseconds required to rise or fall to this new voltage

Drivers providing ramp_delay in regulation_constraints can use this as their set_voltage_time_sel operation.
