[PATCH 0/3] iommu/exynos: Add iommu driver for Exynos4 SoCs

[KyongHo Cho]

Hi.

This patch set enhances System MMU platform device definitions of Exynos
SoC platforms, adds the implementation of IOMMU API as well as and moves
Syste MMU driver to the drivers/iommu directory.

The IOMMU driver also implements fault handler that Ohad Ben-Cohen has
suggeested and iommu_ops per-bus_type that Joerg Roedel suggests.

CONFIG_S5P_SYSTEM_MMU is removed because it is replaceable
with CONFIG_EXYNOS4_IOMMU.
