From cfca3a619baeaba3a0037fef5da48108e9c0bb1c Mon Sep 17 00:00:00 2001 From: Changhwan Youn Date: Mon, 26 Jul 2010 21:13:08 +0900 Subject: ARM: S5PV310: Add Timer support This patch adds timer support for S5PV310. Until now, all S5P SoCs use CONFIG_ARCH_USES_GETTIMEOFFSET macro as a default configuration. Instead,S5PV310 implements clocksource and clock_event_device to support the high resolution timer and tickless system.
