7 - compatible: "virtio,mmio" compatibility string
8 - reg: control registers base address and size including configuration space
9 - interrupts: interrupt generated by the device
11 Required properties for virtio-iommu:
13 - #iommu-cells: When the node corresponds to a virtio-iommu device, it is
14 linked to DMA masters using the "iommus" or "iommu-map"
15 properties [1][2]. #iommu-cells specifies the size of the
16 "iommus" property. For virtio-iommu #iommu-cells must be

H A Diommu.txt1 * virtio IOMMU PCI device
3 When virtio-iommu uses the PCI transport, its programming interface is
5 device tree statically describes the relation between IOMMU and DMA
6 masters. Therefore, the PCI root complex that hosts the virtio-iommu
7 contains a child node representing the IOMMU device explicitly.
11 - compatible: Should be "virtio,pci-iommu"
12 - reg: PCI address of the IOMMU. As defined in the PCI Bus
13 Binding reference [1], the reg property is a five-cell
18 - #iommu-cells: Each platform DMA master managed by the IOMMU is assigned
20 For virtio-iommu, #iommu-cells must be 1.
