[PATCH v8 2/7] dt-bindings: virtio: Add virtio-pci-iommu node

2019-05-30 Thread Jean-Philippe Brucker
Some systems implement virtio-iommu as a PCI endpoint. The operating system needs to discover the relationship between IOMMU and masters long before the PCI endpoint gets probed. Add a PCI child node to describe the virtio-iommu device. The virtio-pci-iommu is conceptually split between a PCI
