I would rather, if there is no need for such a long delay like

I just though of allowing the reset to take longer as I have no idea how
long it could take, let alone other versions of OMAP.
I would say that ndelay(1) just doesn't look relevant to < 1 GHz
cpus :-)
Good point. On ARM ndelay(1) seems to be equal to udelay(1) at the moment.
I actually just removed the ndelay(1) and again, "delay" won't get past
1 if I print it after the loop.
It'd be nice to know how it works on other OMAP versions before making
such changes. :-)
Let me know if you come up with a refreshed patch for this, ignoring
for now.
I think the need for this patch has largely gone away as i2c-omap
appears not to do msleep() anymore for every second transfer or so.
