Merge tag 'iommu-updates-v4.20' of git://git.kernel.org/pub/scm/linux/kernel/git/joro/iommu
Pull IOMMU updates from Joerg Roedel: - Debugfs support for the Intel VT-d driver. When enabled, it now also exposes some of its internal data structures to user-space for debugging purposes. - ARM-SMMU driver now uses the generic deferred flushing and fast-path iova allocation code. This is expected to be a major performance improvement, as this allocation path scales a lot better. - Support for r8a7744 in the Renesas iommu driver - Couple of minor fixes and improvements all over the place * tag 'iommu-updates-v4.20' of git://git.kernel.org/pub/scm/linux/kernel/git/joro/iommu: (39 commits) iommu/arm-smmu-v3: Remove unnecessary wrapper function iommu/arm-smmu-v3: Add SPDX header iommu/amd: Add default branch in amd_iommu_capable() dt-bindings: iommu: ipmmu-vmsa: Add r8a7744 support iommu/amd: Move iommu_init_pci() to .init section iommu/arm-smmu: Support non-strict mode iommu/io-pgtable-arm-v7s: Add support for non-strict mode iommu/arm-smmu-v3: Add support for non-strict mode iommu/io-pgtable-arm: Add support for non-strict mode iommu: Add "iommu.strict" command line option iommu/dma: Add support for non-strict mode iommu/arm-smmu: Ensure that page-table updates are visible before TLBI iommu/arm-smmu-v3: Implement flush_iotlb_all hook iommu/arm-smmu-v3: Avoid back-to-back CMD_SYNC operations iommu/arm-smmu-v3: Fix unexpected CMD_SYNC timeout iommu/io-pgtable-arm: Fix race handling in split_blk_unmap() iommu/arm-smmu-v3: Fix a couple of minor comment typos iommu: Fix a typo iommu: Remove .domain_{get,set}_windows iommu: Tidy up window attributes ...
