From f64691b3ab795268072e76ddb89290b6277cdf33 Mon Sep 17 00:00:00 2001 From: "Mark A. Greer" Date: Wed, 15 Apr 2009 12:40:11 -0700 Subject: davinci: Add base address and timer flexibility The davinci timer code currently hardcodes the timer register base addresses, the timer irq numbers, and the timers to use for clock events and clocksource. This won't work for some a new SoC so put those values into the soc_info structure and set them up in the SoC-specific files. Signed-off-by: Mark A.
