The generic driver makes use of the ppc_md.*_rtc_time hooks, so that's the right place to start. See include/asm-ppc/genrtc.h for the PPC-specific portions of the genrtc driver, and these bits are what have to return the right values for your board/rtc chip. -- Tom Rini http://gate.crashing.org/~trini/ ** Sent via the linuxppc-embedded mail list.
