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)
