[lm-sensors] [PATCH 2/2] Add support for Maxim/Dallas DS1374

[rvinson@mvista.com (Randy Vinson)]

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.
