Subject: [PATCH 2/2] Add support for Maxim/Dallas DS1374 Real-Time Clock Chip

From: Randy Vinson <[email-masked]>

Greetings,
  This is part 2 of the patch to add support for the DS1374 I2C RTC chip
from Maxim/Dallas.

		Randy Vinson

Add support for the I2C Real-Time Clock on the MPC8349ADS board.

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.
