From 91cfbd4ee0875f8a826731983378670012ba6e01 Mon Sep 17 00:00:00 2001 From: Thomas Abraham Date: Fri, 27 Jan 2012 15:25:00 +0900 Subject: ARM: EXYNOS: Hook up power domains to generic power domain infrastructure Add support for generic power domain for Exynos4 platforms and remove the Samsung specific power domain control for Exynos4. The generic power domain infrastructure is used to control the power domains available on Exynos4. For non-dt platforms, the power domains are statically instantiated. For dt platforms, the power domain nodes found in the device tree are instantiated. Cc: Kyungmin Park Cc: Rob Herring Cc: Grant Likely Signed-off-by: Thomas Abraham Acked-by: Rafael J.
