[PATCH v3 0/2] drm/nouveau: tegra: Detach from ARM DMA/IOMMU mapping
From: Thierry Reding <treding at nvidia.com>
An unfortunate interaction between the 32-bit ARM DMA/IOMMU mapping code
and Tegra SMMU driver changes to support IOMMU groups introduced a boot-
time regression on Tegra124. This was caught very late because none of
the standard configurations that are tested on Tegra enable the ARM DMA/
IOMMU mapping code since it is not needed.
The reason for
