From 66b848e487ab8655815437993951ee26cc3c593f Mon Sep 17 00:00:00 2001 From: viresh kumar Date: Fri, 20 May 2011 08:34:19 +0100 Subject: ARM: 6927/1: SPEAr Clock: Update for single image solution This patch creates different clk_lookup arrays for individual machines. These lookup arrays will be registered only if that specific machine is current machine.
