He said that hr_timer support is perceivable _when he is driving vibration motor_. Which he should not do in the first place.
Yes, if the difference is perceivable with LED in non-crazy configuration (*), we can take the patch. Is it? Do we have someone not from Google observing it?
Pavel (*) emulating PWM using blink trigger counts as "crazy" :-)
