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Add bindings for MT6795 M4U iommu/iova: Fix module config properly iommu/amd: Fix sparse warning iommu/amd: Remove outdated comment iommu/amd: Free domain ID after domain_flush_pages iommu/amd: Free domain id in error path iommu/virtio: Fix compile error with viommu_capable() ...

dt-bindings: iommu: arm,smmu-v3: Relax order of interrupt names

2022-09-26T12:05:58Z

The QEMU devicetree uses a different order for SMMUv3 interrupt names, and there isn't a good reason for enforcing a specific order. Since all interrupt lines are optional, operating systems should not expect a fixed interrupt array layout; they should instead match each interrupt to its name individually. Besides, as a result of commit e4783856a2e8 ("dt-bindings: iommu: arm,smmu-v3: make PRI IRQ optional"), "cmdq-sync" and "priq" are already permutable. Relax the interrupt-names array entirely by allowing any permutation, incidentally making the schema more readable. Note that dt-validate won't allow duplicate names here so we don't need to specify maxItems or add additional checks, it's quite neat.

dt-bindings: Remove 'Device Tree Bindings' from end of title:

2022-08-25T19:06:57Z

As indicated in link: https://lore.kernel.org/all/20220822204945.GA808626-robh@kernel.org/ DT schema files should not have 'Device Tree Binding' as part of there title: line. Remove this in most .yaml files, so hopefully preventing developers copying it into new .yaml files, and being asked to remove it.

2022-06-22T13:44:25Z

Add property "mediatek,infracfg" to let the mtk_iommu driver retrieve a phandle to the infracfg syscon instead of performing a per-soc compatible lookup in the entire devicetree and set it as a required property for MT2712 and MT8173.

dt-bindings: Add xen,grant-dma IOMMU description for xen-grant DMA ops

2022-06-06T14:07:30Z

The main purpose of this binding is to communicate Xen specific information using generic IOMMU device tree bindings (which is a good fit here) rather than introducing a custom property. Introduce Xen specific IOMMU for the virtualized device (e.g. virtio) to be used by Xen grant DMA-mapping layer in the subsequent commit. The reference to Xen specific IOMMU node using "iommus" property indicates that Xen grant mappings need to be enabled for the device, and it specifies the ID of the domain where the corresponding backend resides. The domid (domain ID) is used as an argument to the Xen grant mapping APIs. This is needed for the option to restrict memory access using Xen grant mappings to work which primary goal is to enable using virtio devices in Xen guests.
