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
+
- "hsio"
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 and
21
+
frame injection
22
+
- interrupt-names: should contain the interrupt names: "xtr", "inj"
23
+
- ethernet-ports: A container for child nodes representing switch ports.
24
+
25
+
The ethernet-ports container has the following properties
26
+
27
+
Required properties:
28
+
29
+
- #address-cells: Must be 1
30
+
- #size-cells: Must be 0
31
+
32
+
Each port node must have the following mandatory properties:
33
+
- reg: Describes the port address in the switch
34
+
35
+
Port nodes may also contain the following optional standardised
36
+
properties, described in binding documents:
37
+
38
+
- phy-handle: Phandle to a PHY on an MDIO bus. See
39
+
Documentation/devicetree/bindings/net/ethernet.txt for details.
