   1 Microsemi Ocelot network Switch
   2 ===============================
   3
   4 The Microsemi Ocelot network switch can be found on Microsemi SoCs (VSC7513,
   5 VSC7514)
   6
   7 Required properties:
   8 - compatible: Should be "mscc,vsc7514-switch"
   9 - reg: Must contain an (offset, length) pair of the register set for each
  10   entry in reg-names.
  11 - reg-names: Must include the following entries:
  12   - "sys"
  13   - "rew"
  14   - "qs"
  15   - "ptp" (optional due to backward compatibility)
  16   - "qsys"
  17   - "ana"
  18   - "portX" with X from 0 to the number of last port index available on that
  19     switch
  20 - interrupts: Should contain the switch interrupts for frame extraction,
  21   frame injection and PTP ready.
  22 - interrupt-names: should contain the interrupt names: "xtr", "inj". Can contain
  23   "ptp_rdy" which is optional due to backward compatibility.
  24 - ethernet-ports: A container for child nodes representing switch ports.
  25
  26 The ethernet-ports container has the following properties
  27
  28 Required properties:
  29
  30 - #address-cells: Must be 1
  31 - #size-cells: Must be 0
  32
  33 Each port node must have the following mandatory properties:
  34 - reg: Describes the port address in the switch
  35
  36 Port nodes may also contain the following optional standardised
  37 properties, described in binding documents:
  38
  39 - phy-handle: Phandle to a PHY on an MDIO bus. See
  40   Documentation/devicetree/bindings/net/ethernet.txt for details.
