     12description:
     13  Many data items that are represented in a pin configuration node are common
     14  and generic. Pin control bindings should use the properties defined below
     15  where they are applicable; not all of these properties are relevant or useful
     16  for all hardware or binding structures. Each individual binding document
     17  should state which of these generic properties, if any, are used, and the
     18  structure of the DT nodes that contain these properties.
