Hi,

This patchset adds support for Tegra IOMMU driver for Tegra2/3.

Presently this driver is specific to Tegra platform, but some of
functionalities could be replaced with a generic IOMMU framework. This
is expected to ease finding similarities with different platforms,
with the intention of solving problems once in a generic framework
which everyone can use.

Originally this was developed under git://nv-tegra.nvidia.com/linux-2.6.git,
and they are cleaned up for upstreaming.

ARM: iommu: tegra2: Initial support for GART driver
ARM: iommu: tegra3: Initial support for SMMU driver
