Device nodes

• Each device node can have:

• Properties, which are data structures describing the node and its associated device

• Methods, which are the software procedures used to access the device

• Data, which are the initial values of the private data used by the methods

• Children, which are other device nodes "attached" to a given node and that lie directly below it in the device tree

• A parent, which is the node that lies directly above a given node in the device tree
