[PATCH 0/4] iommu/exynos: Add IOMMU and Enhance System MMU for Exynos4

[KyongHo Cho]

Hi,

The first 2 patches are the revolutionary change to the device definition
of System MMU for Exynos4 SoCs:
 - System MMU ID is removed and a device and its dedicated System MMU are
   bound during the machine initialization.
 - Only the System MMU platform devices that are bound to their master
   devices are initialized. If a System MMU is not initialized, it is no
   longer available.
 - Clock gating of System MMU with clkdev.
 - Moved System MMU driver to the IOMMU's dedicated directory,
   drivers/iommu.

The last 2 patches introduce new IOMMU API implementation for Exynos4
System MMU. They implements all IOMMU API including Ohad's latest
suggestion about MMU fault handling and Joerg's suggestion about
bus_type.
