From 882c0518e5317a41834d0fceee07ae6ada2d7429 Mon Sep 17 00:00:00 2001 From: Tony Lindgren Date: Fri, 12 Feb 2010 12:26:46 -0800 Subject: [PATCH] omap: Fix dmtimer.c for multi-omap boot Fix dmtimer.c for multi-omap boot. Also remove legacy clk_enable/disable wrappers that are no longer needed. Note that the clock handling should be further improved to make use of the clock aliases.
