The "packages" node in the device tree

Q: What is the "packages" node in the device tree?

A: This node has children, and instead of describing a device, it describes the various support packages that devices can use. Remember that the device tree is an object-oriented structure and children inherit their parent's functionality. Here is a property dump of that node on a G3. Note that a support node does not require a unit-address as part of its node name.
