+title: Generic Pin Configuration Node

+
+description:
+ Many data items that are represented in a pin configuration node are common
+ and generic. Pin control bindings should use the properties defined below
+ where they are applicable; not all of these properties are relevant or useful
+ for all hardware or binding structures. Each individual binding document
+ should state which of these generic properties, if any, are used, and the
+ structure of the DT nodes that contain these properties.
