     12description:
     13  The Xen IOMMU represents the Xen grant table interface. Grant mappings
     14  are to be used with devices connected to the Xen IOMMU using the "iommus"
     15  property, which also specifies the ID of the backend domain.
     16  The binding is required to restrict memory access using Xen grant mappings.
