Microsemi Ocelot network Switch
===============================

The Microsemi Ocelot network switch can be found on Microsemi SoCs (VSC7513,
VSC7514)

Required properties:
- compatible: Should be "mscc,vsc7514-switch"
- reg: Must contain an (offset, length) pair of the register set for each
  entry in reg-names.
- reg-names: Must include the following entries:
  - "sys"
  - "rew"
  - "qs"
  - "ptp" (optional due to backward compatibility)
  - "qsys"
  - "ana"
  - "portX" with X from 0 to the number of last port index available on that
    switch
- interrupts: Should contain the switch interrupts for frame extraction,
  frame injection and PTP ready.
- interrupt-names: should contain the interrupt names: "xtr", "inj". Can contain
  "ptp_rdy" which is optional due to backward compatibility.
- ethernet-ports: A container for child nodes representing switch ports.

The ethernet-ports container has the following properties

Required properties:

- #address-cells: Must be 1
- #size-cells: Must be 0

Each port node must have the following mandatory properties:
- reg: Describes the port address in the switch

Port nodes may also contain the following optional standardised
properties, described in binding documents:

- phy-handle: Phandle to a PHY on an MDIO bus. See
  Documentation/devicetree/bindings/net/ethernet.txt for details.
