Then you'll break mioa701 board, which is pxa270 based. The RYCR/RDCR were
introduced on PXA27x chips, so the rtc-pxa driver should work on pxa27x SoCs.
The behaviour should be as before, the config should be able to choose between
rtc-pxa and rtc-sa1100 for a pxa27x based board. For sharpsl_pm, I suppose the
rtc-sa1100 will be chosen in the .config, and for mioa701, it will be
rtc-pxa.
Just to clear, I'm against removing "resources, clock" from pxa27x platform code
which would break rtc-pxa driver on pxa27x. Now I don't care if you're talking
about changing some "defconfigs".
Cheers.
