From fd717cd7c995644d149a5481c3894b748c082909 Mon Sep 17 00:00:00 2001 From: Marek Szyprowski Date: Sat, 12 May 2012 06:17:59 +0900 Subject: ARM: EXYNOS: use s5p-timer for UniversalC210 board Commit 069d4e743 ("ARM: EXYNOS4: Remove clock event timers using ARM private timers") removed support for local timers and forced to use MCT as event source. However MCT is not operating properly on early revision of EXYNOS4 SoCs. All UniversalC210 boards are based on it, so that commit broke support for it. This patch provides a workaround that enables UniversalC210 boards to boot again. s5p-timer is used as an event source, it works only for non-SMP builds.
