Subject: I2C: Add support for Maxim/Dallas DS1374 Real-Time Clock Chip (2/2)

From: Randy Vinson <[email-masked]>
Date: Fri, 03 Jun 2005 14:43:56 -0700

This change provides support for the DS1374 Real-Time Clock chip present
on the MPC8349ADS board. It depends on a previous patch which adds I2C
support for the DS1374.
