    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.
   41 
   42 Example:
   43 
   44         switch@1010000 {
   45                 compatible = "mscc,vsc7514-switch";
