Subject: [PATCH v3 0/2] ARM: IOMMU: tegra: Add iommu_ops for GART/SMMU driver

This patchset adds support for IOMMU API for Tegra20(GART) and
Tegra30(SMMU). "struct iommu_ops" are implemented for both H/W IOMMU
modules.

Tested with "Ion memory manager" and "DMA mapping API"(*1).

This was originally developed with Tegra specific IOMMU
API(tegra_iovmm_*()) in:

git://nv-tegra.nvidia.com/linux-2.6.git.

v2:
https://lkml.org/lkml/2011/12/15/203

v1:
https://lkml.org/lkml/2011/11/17/111
