.e. support also DS1388 for example, so I was wondering if the DS1374 could=
 be just squeezed in as well? See http://people.freebsd.org/~raj/patches/mi=
sc/ds13xx.diff

I had a quick look at the datasheets, the 1374 registers uses a  time
of day counter, while the 133x uses a BCD coded date representation.

The other features which we do not support now(alarm/watchdog etc)
also seems different, so merging the drivers may not result in
reducing code.
