From ed1c7de29f9f3d56b3ca5ef69682cc1a3d369e9d Mon Sep 17 00:00:00 2001 From: Tony Lindgren Date: Fri, 2 Nov 2012 12:24:06 -0700 Subject: ARM: OMAP2+: Move iommu2 to drivers/iommu/omap-iommu2.c This file should not be in arch/arm. Move it to drivers/iommu to allow making most of the header local to drivers/iommu. This is needed as we are removing plat and mach includes from drivers for ARM common zImage support.
