For the timer trigger I would pretty much like my approach to stay.
The reason is that the PWM I need to do, is not strictly a PWM -
it needs the ON period in range of tens or hundreds of milliseconds,

This is 1000 times better than without my patch - the precision
was 10ms (jiffy).

Hi Stas,
Have you tested it? 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.
