Agreed, what's wrong with drivers/char/rtc.c? It even works for the
DECstation which maps its RTC in an unusual (but nice) way -- it's just a
matter of initializing rtc_ops appropriately. See arch/mips/dec/rtc-dec.c
for an example.
Unless you use a non-MC146818 RTC, which you need to write a separate
driver for anyway.
