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.
