+Microsemi Felix network Switch
+==============================
+
+The Felix switch device is the Microsemi VSC9959 gigabit ethernet
+switch core integrated as a PCIe endpoint device.
+
+Required properties:
+- compatible	: Should be "mscc,felix-switch"
+- reg		: Specifies PCIe Device Number and Function
+		  Number of the integrated endpoint device,
+		  according to parent node bindings.
+- ethernet-ports: A container of child nodes representing
+		  switch ports.
+
+"ethernet-ports" container has the following required properties:
+- #address-cells: Must be 1
+- #size-cells	: Must be 0
+
+A list of child nodes representing switch ports is expected.
+Each child port node must have the following mandatory property:
+- reg		: port id (address) in the switch (0..N-1)
+
+Port nodes may also contain the following optional standardised
+properties, described in corresponding binding documents:
+
+- phy-handle	: Phandle to a PHY on a MDIO bus. See
+		  Documentation/devicetree/bindings/net/ethernet.txt
+
+or,
+- fixed-link	: "fixed-link" node, for internal ports or external
+		  fixed-link connections. See
+		  Documentation/devicetree/bindings/net/fixed-link.txt
+
+Example:
+
+	switch@0,5 {
+		compatible = "mscc,felix-switch"
+		reg = <0x000500 0 0 0 0>;
+
+		ethernet-ports {
+			#address-cells = <1>;
+			#size-cells = <0>;
+
+			/* external ports */
+			switch_port0: port@0 {
+				reg = <0>;
+				phy-handle = <&phy0>;
+			};
+			switch_port1: port@1 {
+				reg = <1>;
+				phy-handle = <&phy1>;
+			};
+			switch_port2: port@2 {
+				reg = <2>;
+				phy-handle = <&phy2>;
+			};
+			switch_port3: port@3 {
+				reg = <3>;
+				phy-handle = <&phy3>;
+			};
+			/* internal to-cpu ports */
+			port@4 {
+				reg = <4>;
+				fixed-link {
+					speed = <1000>;
+					full-duplex;
+				};
+			};
+			port@5 {
+				reg = <5>;
+				fixed-link {
+					speed = <1000>;
+					full-duplex;
+				};
+			};
+		};
+	};
