All right Rob, to conclude this discussion, provided you add to the git comment
what we discussed, ie. that this patch opens the path to exclusive runtime usage
between rtc-sa1100 and rtc-pxa on pxa, I'll ack it.

If somebody complains, I'll tell him to develop the glue between sa1100 and pxa
as Russell suggested, or use only one of the drivers.

Cheers.
