Subject[PATCH v2 2/2] ARM: mach-shmobile: sh7372: Add IPMMU device
Date
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.
