[PATCH 2/2] ARM: mach-shmobile: sh7372: Add IPMMU device
From: Hideki EIRAKU <hidden>

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.
