First 2 patches enhance System MMU platform device definition: - Removed System MMU for MDMA0 in LCD block because it is not used. Use MDMA2 in TOP block. - Removed System MMU ID. Instead a System MMU is bound to a device that the System MMU is dedicated during machin initialization. If a device driver wants to handle System MMU, it must bind its device with System MMU with sysmmu_set_owner(). - clkdev - System MMU device driver is removed from arch/arm/plat-s5p to move it to driver/iommu directory. Last 2 patches implements IOMMU API: - Implements IOMMU API and System MMU driver that is moved from arch/arm/plat-s5p. - Implements fault handling that is suggested by Ohad. - Used bus_set_iommu instead of register_iommu that is suggested by Joerg.
