[PATCH v2 1/5] drm/nouveau: tegra: Detach from ARM DMA/IOMMU mapping
From: Thierry Reding <treding at nvidia.com>
Depending on the kernel configuration, early ARM architecture setup code
may have attached the GPU to a DMA/IOMMU mapping that transparently uses
the IOMMU to back the DMA API. Tegra requires special handling for IOMMU
backed buffers (a special bit in the GPU's MMU page tables indicates the
memory path to take: via the SMMU or directly to the
