description: Binding for the Power Sourcing Equipment (PSE) as defined in the

  IEEE 802.3 specification. It is designed for hardware which is delivering

  power over twisted pair/ethernet cable. The ethernet-pse nodes should be

  used to describe PSE controller and referenced by the ethernet-phy node.
