Remove the hardcode definition of rtc registers, use
ioremap()instead. Append clk support for arch-mmp, so add dummy clk in arch-sa1100/arch-pxa.

What is the status of the
drivers/rtc/rtc-pxa.cdriver after this series? Is is still required for some pxa machines or can it get removed now? It seems a little strange to register two platform devices for the rtc on each pxa machine, with the same resources.Yes, it's very strange to support two RTC wrappers at the same time. So rtc-pxa is removed in pxa27x/pxa3xx after this patch series. It only exists in pxa95x.
What is the reason for this? Wouldn't it be easier to move pxa95x over to use the same driver as well? I guess that can be a series for another time, but it seems like you are almost at the point where you can remove the other driver entirely.
