> Hi.

> 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.
