+* Xen hypervisor device tree bindings
+
+Xen ARM virtual platforms shall have the following properties:
+
+- compatible:
+	compatible = "xen,xen", "xen,xen-<version>";
+  where <version> is the version of the Xen ABI of the platform.
+
+- reg: specifies the base physical address and size of a region in
+  memory where the grant table should be mapped to, using an
+  HYPERVISOR_memory_op hypercall. 
+
+- interrupts: the interrupt used by Xen to inject event notifications.
+
+
+Example:
+
+hypervisor {
+	compatible = "xen,xen", "xen,xen-4.3";
+	reg = <0xb0000000 0x20000>;
+	interrupts = <1 15 0xf08>;
+};
