udelay(20000) is probably not a good idea. You should probably use
something like usleep_range() or msleep() here. Also see:
Documentation/timers/timers-howto.txt
Thierry,
thanks for mentioning this. I clearly got distracted from ms to us
switch due to the different reset API convention. As the delay will
be most likely 10ms+, we should change the above to
msleep(reset_udelay/1000) instead.
