From f671e0224a7f6432abdd9935bc34d959f5a67e21 Mon Sep 17 00:00:00 2001 From: Hideki EIRAKU Date: Mon, 21 Jan 2013 19:54:29 +0900 Subject: [PATCH] ARM: mach-shmobile: r8a7740: Add IPMMU device This patch adds an IPMMU device and notifies the IPMMU driver which devices are connected via the IPMMU module. All devices connected to the main memory bus via the IPMMU module MUST be registered when SHMOBILE_IPMMU and SHMOBILE_IOMMU are enabled because physical address cannot be used while the IPMMU module's MMU function is enabled.
