All Tegra DRM devices are getting attached to an implicit IOMMU DMA domain if CONFIG_ARM_DMA_USE_IOMMU=y. Since Tegra DRM driver manages IOMMU by itself, the devices must be detached from the implicit domain using arch-specific IOMMU-API. Note that this works only for arm32 and not for arm64, which will remain broken if CONFIG_IOMMU_DMA is enabled. Signed-off-by:Dmitry Osipenko <digetx@gmail.com> Signed-off-by:
