GART driver wasn't ever been utilized in upstream, but finally this should
change sometime soon with Tegra's DRM driver rework. In general GART driver
works fine, though there are couple things that could be improved.

Dmitry Osipenko (4):
  iommu/tegra: gart: Add debugging facility
  iommu/tegra: gart: Fix gart_iommu_unmap()
  iommu/tegra: gart: Constify number of GART pages
  iommu/tegra: gart: Optimize map/unmap
