dt-bindings: net: add DT bindings for Microsemi Ocelot Switch

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"

  - "hsio"

  - "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 and

  frame injection

- interrupt-names: should contain the interrupt names: "xtr", "inj"

- 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.
