From 0dc018ece13effc689e47479ea9ebf1c98a507f5 Mon Sep 17 00:00:00 2001 From: Stefan Roese Date: Tue, 20 Feb 2007 10:51:26 +0100 Subject: [PATCH] I2C: Add support for multiple I2C busses for RTC & DTT This patch switches to the desired I2C bus when the date/dtt commands are called. This can be configured using the CFG_RTC_BUS_NUM and/or CFG_DTT_BUS_NUM defines.
