+description:
+  This binding specifies what properties must be available in the device tree
+  representation of an Open PIC compliant interrupt controller.  This binding is
+  based on the binding defined for Open PIC in [1] and is a superset of that
+  binding.

+    description:
+      Some MPICs do not correctly report the number of hardware sources in the
