39 Nodes  section in Syntax and structure
42 Like any tree data structure, a devicetree has a hierarchy of *nodes*.
43 The above tree has three nodes:
51 Nodes can be assigned *node labels*, which are unique shorthands that refer to  argument
56 Devicetree nodes have *paths* identifying their locations in the tree. Like
66 Devicetree nodes can also have *properties*. Properties are name/value pairs.
79 In practice, devicetree nodes usually correspond to some hardware, and the node
