Shudder.
Actually, that's where I got the kernel part of the code I just sent. :-) The userland bit I wrote myself. I've just remembered. To get this driver to work you have to change a line in m8xx_setup.c from: unsigned long __init m8xx_get_rtc_time(void) to: unsigned long m8xx_get_rtc_time(void) Alex ** Sent via the linuxppc-embedded mail list.
