#     Merge tag 'iommu-updates-v5.8' of git://git.kernel.org/pub/scm/linux/kernel/git/joro/iommu
#     
#     Pull iommu updates from Joerg Roedel:
#      "A big part of this is a change in how devices get connected to IOMMUs
#       in the core code. It contains the change from the old add_device() /
#       remove_device() to the new probe_device() / release_device()
#       call-backs.
#     
#       As a result functionality that was previously in the IOMMU drivers has
#       been moved to the IOMMU core code, including IOMMU group allocation
#       for each device. The reason for this change was to get more robust
#       allocation of default domains for the iommu groups.
#     
#       A couple of fixes were necessary after this was merged into the IOMMU
#       tree, but there are no known bugs left. The last fix is applied on-top
#       of the merge commit for the topic branches.
#     
#       Other than that change, we have:
#     
#        - Removal of the driver private domain handling in the Intel VT-d
#          driver. This was fragile code and I am glad it is gone now.
#     
#        - More Intel VT-d updates from Lu Baolu:
#           - Nested Shared Virtual Addressing (SVA) support to the Intel VT-d
#             driver
#           - Replacement of the Intel SVM interfaces to the common IOMMU SVA
#             API
#           - SVA Page Request draining support
#     
#        - ARM-SMMU Updates from Will:
#           - Avoid mapping reserved MMIO space on SMMUv3, so that it can be
#             claimed by the PMU driver
#           - Use xarray to manage ASIDs on SMMUv3
#           - Reword confusing shutdown message
#           - DT compatible string updates
#           - Allow implementations to override the default domain type
#     
#        - A new IOMMU driver for the Allwinner Sun50i platform
#     
#        - Support for ATS gets disabled for untrusted devices (like
#          Thunderbolt devices). This includes a PCI patch, acked by Bjorn.
#     
#        - Some cleanups to the AMD IOMMU driver to make more use of IOMMU
#          core features.
#     
#        - Unification of some printk formats in the Intel and AMD IOMMU
#          drivers and in the IOVA code.
#     
#        - Updates for DT bindings
#     
#        - A number of smaller fixes and cleanups.
