Do you want me to touch clock_event_mode as well?
Otherwise we will pass mode into a function setting state..

Or we can do s/mode/state after all the work suggested by you
is done ..

Or leave as is..

1 & 2, should be just 1-2 patches, I will try to send them as soon
as possible. Once these get your nod, will start working on fixing
all the clockevent drivers.
