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.
Regards,
Cho KyongHo.
