[GIT PULL v3 1/4] ARM: tegra: IOMMU support for v3.19

[Thierry Reding]

Hi ARM SoC maintainers,

The following changes since commit 0690cbd2e55a72a8eae557c389d1a136ed9fa142:

  powerpc/iommu: Rename iommu_[un]map_sg functions (2014-11-18 11:30:01 +0100)

  memory: Add NVIDIA Tegra memory controller support (2014-12-04 16:11:47 +0100)

Here's a version of the pull request rebased on top of Joerg's core
branch from the IOMMU tree. It has the advantage of having resolved
the merge conflicts and the disadvantage of pulling in v3.18-rc3.
It also contains an updated commit description with some details
that ensued from a discussion regarding the DT binding as well as
the memory-client to SWGROUP mapping tables.

This pull request also contains fixes for a build error reported by the
0-day builder as well as a couple of issues in the IOMMU domain detach
path that I've found since v2 while doing extensive driver unload and
reload stress testing.

Thanks,
Thierry

This adds the driver pieces required for IOMMU support on Tegra30,
Tegra114 and Tegra124.
