From 25e9d28d927d2e1731df53f60cde53d75bcb7c36 Mon Sep 17 00:00:00 2001 From: Cho KyongHo Date: Wed, 26 Dec 2012 10:54:02 +0900 Subject: ARM: EXYNOS: remove system mmu initialization from exynos tree This removes System MMU initialization from arch/arm/mach-exynos/ to move them to DT and the exynos-iommu driver except gating clock definitions.
