Merge tag 'iommu-updates-v6.1' of git://git.kernel.org/pub/scm/linux/kernel/git/joro/iommu
Pull iommu updates from Joerg Roedel: - remove the bus_set_iommu() interface which became unnecesary because of IOMMU per-device probing - make the dma-iommu.h header private - Intel VT-d changes from Lu Baolu: - Decouple PASID and PRI from SVA - Add ESRTPS & ESIRTPS capability check - Cleanups - Apple DART support for the M1 Pro/MAX SOCs - support for AMD IOMMUv2 page-tables for the DMA-API layer. The v2 page-tables are compatible with the x86 CPU page-tables. Using them for DMA-API prepares support for hardware-assisted IOMMU virtualization - support for MT6795 Helio X10 M4Us in the Mediatek IOMMU driver - some smaller fixes and cleanups * tag 'iommu-updates-v6.1' of git://git.kernel.org/pub/scm/linux/kernel/git/joro/iommu: (59 commits) iommu/vt-d: Avoid unnecessary global DMA cache invalidation iommu/vt-d: Avoid unnecessary global IRTE cache invalidation iommu/vt-d: Rename cap_5lp_support to cap_fl5lp_support iommu/vt-d: Remove pasid_set_eafe() iommu/vt-d: Decouple PASID & PRI enabling from SVA iommu/vt-d: Remove unnecessary SVA data accesses in page fault path dt-bindings: iommu: arm,smmu-v3: Relax order of interrupt names iommu: dart: Support t6000 variant iommu/io-pgtable-dart: Add DART PTE support for t6000 iommu/io-pgtable: Add DART subpage protection support iommu/io-pgtable: Move Apple DART support to its own file iommu/mediatek: Add support for MT6795 Helio X10 M4Us iommu/mediatek: Introduce new flag TF_PORT_TO_ADDR_MT8173 dt-bindings: mediatek: Add bindings for MT6795 M4U iommu/iova: Fix module config properly iommu/amd: Fix sparse warning iommu/amd: Remove outdated comment iommu/amd: Free domain ID after domain_flush_pages iommu/amd: Free domain id in error path iommu/virtio: Fix compile error with viommu_capable() ...
