I tried it with Samsung M0 board and my leds-aat1290 driver. It didn't work well. And for small delay intervals it will not have a chance to work reliably with all drivers, especially the ones which use mutex in their brightness_set op, since mutex can sleep. I am afraid that we have to stay with what we have currently.
