From 6b8858a972a0eff1dc1ab77b0fd9fc25387c217c Mon Sep 17 00:00:00 2001 From: Paul Walmsley Date: Tue, 18 Mar 2008 10:35:15 +0200 Subject: ARM: OMAP2: Change 24xx to use shared clock code and new reg access This patch changes 24xx to use shared clock code and new register access. Note that patch adds some temporary OLD_CK defines to keep patch more readable. These temporary defines will be removed in the next patch. Also not all clocks are changed in this patch to limit the size. Also, the patch fixes few incorrect clock defines in clock24xx.h.
