+Sub-nodes:
+
+GICv3 has one or more Interrupt Translation Services (ITS) that are
+used to route Message Signalled Interrupts (MSI) to the CPUs.
+
+These nodes must have the following properties:
+- compatible : Should at least contain  "arm,gic-v3-its".
+- msi-controller : Boolean property. Identifies the node as an MSI controller
+- reg: Specifies the base physical address and size of the ITS
+  registers.
+
+The main GIC node must contain the appropriate #address-cells,
+#size-cells and ranges properties for the reg property of all ITS
+nodes.
