+        A pin multiplexing sub-node describes how to configure a set of (or a
+        single) pin in some desired alternate function mode.
+        A single sub-node may define several pin configurations.

+            Integer array representing pin number and pin multiplexing
+            configuration.
+            When a pin has to be configured in alternate function mode, use
+            this property to identify the pin by its global index, and provide
+            its alternate function configuration number along with it.
