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) * tag 'iommu-updates-v5.9' of git://git.kernel.org/pub/scm/linux/kernel/git/joro/iommu: (77 commits) iommu/amd: Move Kconfig and Makefile bits down into amd directory iommu/vt-d: Move Kconfig and Makefile bits down into intel directory iommu/arm-smmu: Move Arm SMMU drivers into their own subdirectory iommu/vt-d: Skip TE disabling on quirky gfx dedicated iommu iommu: Add gfp parameter to io_pgtable_ops->map() iommu: Mark __iommu_map_sg() as static iommu/vt-d: Rename intel-pasid.h to pasid.h iommu/vt-d: Add page response ops support iommu/vt-d: Report page request faults for guest SVA iommu/vt-d: Add a helper to get svm and sdev for pasid iommu/vt-d: Refactor device_to_iommu() helper iommu/vt-d: Disable multiple GPASID-dev bind iommu/vt-d: Warn on out-of-range invalidation address iommu/vt-d: Fix devTLB flush for vSVA iommu/vt-d: Handle non-page aligned address iommu/vt-d: Fix PASID devTLB invalidation iommu/vt-d: Remove global page support in devTLB flush iommu/vt-d: Enforce PASID devTLB field mask iommu: Make some functions static iommu/amd: Remove double zero check ...
