I am tempted to NAK this right here. I would like to see ticks as an
internal implementation detail only, and only be used as far as it is
necessary to provide proper scaled timer services. All public
interfaces shall always only used scaled units.
Again: what's wrong with the us based udelay() and the ms based
get_timer() we have now?
Best regards,
