+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.
+
+Example:
+
+	switch@1010000 {
+		compatible = "mscc,vsc7514-switch";
+		reg = <0x1010000 0x10000>,

+		      <0x1800000 0x80000>,
+		      <0x1880000 0x10000>;
+		reg-names = "sys", "rew", "qs", "hsio", "port0",
+			    "port1", "port2", "port3", "port4", "port5",
+			    "port6", "port7", "port8", "port9", "port10",
+			    "qsys", "ana";
+		interrupts = <21 22>;
+		interrupt-names = "xtr", "inj";
+
+		ethernet-ports {
+			#address-cells = <1>;
