#     Merge tag 'iommu-updates-v5.19' of git://git.kernel.org/pub/scm/linux/kernel/git/joro/iommu
#     
#     Pull iommu updates from Joerg Roedel:
#     
#      - Intel VT-d driver updates:
#          - Domain force snooping improvement.
#          - Cleanups, no intentional functional changes.
#     
#      - ARM SMMU driver updates:
#          - Add new Qualcomm device-tree compatible strings
#          - Add new Nvidia device-tree compatible string for Tegra234
#          - Fix UAF in SMMUv3 shared virtual addressing code
#          - Force identity-mapped domains for users of ye olde SMMU legacy
#            binding
#          - Minor cleanups
#     
#      - Fix a BUG_ON in the vfio_iommu_group_notifier:
#          - Groundwork for upcoming iommufd framework
#          - Introduction of DMA ownership so that an entire IOMMU group is
#            either controlled by the kernel or by user-space
#     
#      - MT8195 and MT8186 support in the Mediatek IOMMU driver
#     
#      - Make forcing of cache-coherent DMA more coherent between IOMMU
#        drivers
#     
#      - Fixes for thunderbolt device DMA protection
#     
#      - Various smaller fixes and cleanups
