I took a brief look at the delayed timer and I think the deferrable
timer should be more a preferred option because this devfreq drive is
more an assistance for the optimal bandwidth selection and it will be
more preferred to keep system idling whenever possible.

My primary concern is the initial performance lag in a case of
multimedia applications. But this will be resolved by hooking up
performance voting to all drivers, once we will get around to it.
