2023-06-05dt-bindings: arm-smmu: Add SM6375 GPU SMMUKonrad Dybcio
SM6375 has a "Qualcomm SMMU V2" implementation for its GPU SMMU. It does not however qualify for the qcom,adreno-smmu compatible, as it can not do split pagetables. It consumes a single clock and a single genpd.

Remove qcom,sm61[12]5-smmu-500 from the "no clocks" list (intentionally 'breaking' the schema checks of APPS SMMU, as now it *can* accept clocks - with the current structure of this file it would have taken a wastefully-long time to sort this out properly..) and add necessary yaml to describe the clocks required by the GPU SMMUs.

SMMUs using only generic compatibles, e.g. arm,mmu-500, which have a variable clocks on different implementations.

Add generic bindings for the Qualcomm variant of the ARM MMU-500.

Note: I have split the sdx55 and sdx65 from the legacy bindings. They are not supported by the qcom SMMU implementation.

2022-09-26dt-bindings: iommu: arm,smmu-v3: Relax order of interrupt namesJean-Philippe Brucker
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.

2022-06-06dt-bindings: Add xen,grant-dma IOMMU description for xen-grant DMA opsOleksandr Tyshchenko
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.
