Merge tag 'iommu-updates-v6.7' of git://git.kernel.org/pub/scm/linux/kernel/git/joro/iommu
Pull iommu updates from Joerg Roedel: "Core changes: - Make default-domains mandatory for all IOMMU drivers - Remove group refcounting - Add generic_single_device_group() helper and consolidate drivers - Cleanup map/unmap ops - Scaling improvements for the IOVA rcache depot - Convert dart & iommufd to the new domain_alloc_paging() ARM-SMMU: - Device-tree binding update: - Add qcom,sm7150-smmu-v2 for Adreno on SM7150 SoC - SMMUv2: - Support for Qualcomm SDM670 (MDSS) and SM7150 SoCs - SMMUv3: - Large refactoring of the context descriptor code to move the CD table into the master, paving the way for '->set_dev_pasid()' support on non-SVA domains - Minor cleanups to the SVA code Intel VT-d: - Enable debugfs to dump domain attached to a pasid - Remove an unnecessary inline function AMD IOMMU: - Initial patches for SVA support (not complete yet) S390 IOMMU: - DMA-API conversion and optimized IOTLB flushing And some smaller fixes and improvements" * tag 'iommu-updates-v6.7' of git://git.kernel.org/pub/scm/linux/kernel/git/joro/iommu: (102 commits) iommu/dart: Remove the force_bypass variable iommu/dart: Call apple_dart_finalize_domain() as part of alloc_paging() iommu/dart: Convert to domain_alloc_paging() iommu/dart: Move the blocked domain support to a global static iommu/dart: Use static global identity domains iommufd: Convert to alloc_domain_paging() iommu/vt-d: Use ops->blocked_domain iommu/vt-d: Update the definition of the blocking domain iommu: Move IOMMU_DOMAIN_BLOCKED global statics to ops->blocked_domain Revert "iommu/vt-d: Remove unused function" iommu/amd: Remove DMA_FQ type from domain allocation path iommu: change iommu_map_sgtable to return signed values iommu/virtio: Add __counted_by for struct viommu_request and use struct_size() iommu/vt-d: debugfs: Support dumping a specified page table iommu/vt-d: debugfs: Create/remove debugfs file per {device, pasid} iommu/vt-d: debugfs: Dump entry pointing to huge page iommu/vt-d: Remove unused function iommu/arm-smmu-v3-sva: Remove bond refcount iommu/arm-smmu-v3-sva: Remove unused iommu_sva handle iommu/arm-smmu-v3: Rename cdcfg to cd_table ...
