> This means that currently video memory is limited to 32 MB, the size of
> the GART aperture.

I guess that the following 2 patches can be merged now, independet of
the rest of drm patches.

  [RFC 1/4] iommu: tegra/gart: use correct gart_device
  [RFC 2/4] iommu: tegra/gart: Add device tree support
