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.
