Subject: [PATCH 2/2] Add support for Maxim/Dallas DS1374 Real-Time Clock Chip
Date: Fri, 03 Jun 2005 14:43:56 -0700 [thread overview]
Message-ID: <42A0CF1C.6000900@mvista.com> (raw)
In-Reply-To: <42A0CD46.60300@mvista.com>
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.
