Hi, here is the second version of this patch-set. The first version with some more introductory text can be found here: https://lore.kernel.org/lkml/20200407183742.4344-1-joro at 8bytes.org/ Changes v1->v2: * Rebased to v5.7-rc1 * Re-wrote the arm-smmu changes as suggested by Robin Murphy * Re-worked the Exynos patches to hopefully not break the driver anymore * Fixed a missing

Hi, here is a patch-set to remove all calls of iommu_group_get_for_dev() from the IOMMU drivers and move the per-device group setup and default domain allocation into the IOMMU core code. This eliminates some ugly back and forth between IOMMU core code and the IOMMU drivers, where the driver called iommu_group_get_for_dev() which itself called back into the driver. The patch-set started as a
