From a443a6373d8527657cfde3d3c515d4a64532c585 Mon Sep 17 00:00:00 2001 From: Thomas Abraham Date: Fri, 14 May 2010 16:27:28 +0900 Subject: ARM: S5PC100: Pre-requisite clock patch for plat-s5pc1xx to plat-s5p move This is a pre-requisite clock patch for the plat-s5pc1xx to plat-s5p movement. The patches that perform the movement of the code from plat-s5pc1xx to plat-s5p (and mach-s5pc100) should also enable the build for the mach-s5pc100/clock.c code.
