I just noticed that the implementation of udelay() - i.e udelay_masked() - resets the timer. Why is that?
Because of a bug?
Why didn't I think of this! ;-)
But seriously what's the point in letting the timer run with 40 or 80 MHz? In my case udelay won't work for delays > 107ms anyway.... :-(

Dunno.

Then make it run slower if you like.
