From db35234ec7a7a10145cf472f68e1c73fbd48f79c Mon Sep 17 00:00:00 2001 From: Chanho Park Date: Wed, 12 Dec 2012 14:04:03 +0900 Subject: [PATCH] ARM: EXYNOS: Add arm-pmu DT binding for exynos421x This patch adds a arm-pmu node to bind device tree for exynos4210. The exynos4210 and 4212 have two cpus which includes a pmu. In contrast, the exynos4412 has 4 cpus and pmus. We need to define two more pmus for this type board. However, supporting arm-pmu for the exynos4412 will handle it later because there is no dts support for 4412 based board.
