Real time clock driver for vaxstations with dallas chip
--- NEW FILE ---
/*
* mc146818.h. macros for /dev/rtc (see drivers/char/rtc.c
* and functions in arch/vax/kernel/time.c
*
* Copyright atp Mar 2002.
*
* Adapted from asm-mips/mc146818rtc.h for decstations.
*
* There are two types of "hardware clock" for the VAX family of
* systems. These are the TODR (time of day register) used on the
* big vaxes, and the standard CMOS clock, which is based on the
* familiar dallas chip, used in the desktop vaxes (KA41, 42, etc..
*
* This file only addresses the desktop vax CMOS clock.
