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.
