Subject: [PATCH 4/4] ARM: EXYNOS4: Add power domain to use generic Power domain Framework

From: [email-masked] (Chanwoo Choi)
Date: Thu, 11 Aug 2011 13:55:22 +0900

This patch initializes the power domain of EXYNOS4210. The devices
which suppot runtime-PM have to be added in specific power domain.
