Easier if those distros just wouldn't select RTC_CLASS then.  :)

And long term, better to work with RTC_CLASS.  Eliminate that
crufty asm-parisc/rtc.h file and one more GEN_RTC user; and
share more widely-used infrastructure.

If I read things right, that would be easy:  the PARISC RTC is
two firmware calls, ptc_tod_{read,set}(), which would map to
RTC class {read,set}_time() methods of about six lines each.
The RTC framework can do UIE emulation, if needed.
