#     Merge tag 'iommu-updates-v5.9' of git://git.kernel.org/pub/scm/linux/kernel/git/joro/iommu
#     
#     Pull iommu updates from Joerg Roedel:
#     
#      - Remove of the dev->archdata.iommu (or similar) pointers from most
#        architectures. Only Sparc is left, but this is private to Sparc as
#        their drivers don't use the IOMMU-API.
#     
#      - ARM-SMMU updates from Will Deacon:
#     
#          - Support for SMMU-500 implementation in Marvell Armada-AP806 SoC
#     
#          - Support for SMMU-500 implementation in NVIDIA Tegra194 SoC
#     
#          - DT compatible string updates
#     
#          - Remove unused IOMMU_SYS_CACHE_ONLY flag
#     
#          - Move ARM-SMMU drivers into their own subdirectory
#     
#      - Intel VT-d updates from Lu Baolu:
#     
#          - Misc tweaks and fixes for vSVA
#     
#          - Report/response page request events
#     
#          - Cleanups
#     
#      - Move the Kconfig and Makefile bits for the AMD and Intel drivers into
#        their respective subdirectory.
#     
#      - MT6779 IOMMU Support
#     
#      - Support for new chipsets in the Renesas IOMMU driver
#     
#      - Other misc cleanups and fixes (e.g. to improve compile test coverage)
#
