+* Qualcomm Atheros QCA8xxx switch family
+
+Required properties:
+
+- compatible: should be one of:
+    "qca,qca8334"
+    "qca,qca8337"
+
+- #size-cells: must be 0
+- #address-cells: must be 1
+
+Subnodes:
+
+The integrated switch subnode should be specified according to the binding
+described in dsa/dsa.txt. As the QCA8K switches do not have a N:N mapping of
+port and PHY id, each subnode describing a port needs to have a valid phandle
+referencing the internal PHY connected to it. The CPU port of this switch is
+always port 0.
+
+A CPU port node has the following optional node:
+
+- fixed-link            : Fixed-link subnode describing a link to a non-MDIO
+                          managed entity. See
+                          Documentation/devicetree/bindings/net/fixed-link.txt
+                          for details.
+
+For QCA8K the 'fixed-link' sub-node supports only the following properties:
+
+- 'speed' (integer, mandatory), to indicate the link speed. Accepted
+  values are 10, 100 and 1000
+- 'full-duplex' (boolean, optional), to indicate that full duplex is
+  used. When absent, half duplex is assumed.
+
+Example:
+
+
+	&mdio0 {
+		phy_port1: phy@0 {
+			reg = <0>;
+		};
+
+		phy_port2: phy@1 {
+			reg = <1>;
+		};
+
+		phy_port3: phy@2 {
+			reg = <2>;
+		};
+
+		phy_port4: phy@3 {
+			reg = <3>;
+		};
+
+		phy_port5: phy@4 {
+			reg = <4>;
+		};
+
+		switch0@0 {
+			compatible = "qca,qca8337";
+			#address-cells = <1>;
+			#size-cells = <0>;
+
+			reg = <0>;
+
+			ports {
+				#address-cells = <1>;
+				#size-cells = <0>;
+				port@0 {
+					reg = <0>;
+					label = "cpu";
+					ethernet = <&gmac1>;
+					phy-mode = "rgmii";
+					fixed-link {
+						speed = 1000;
+						full-duplex;
+					};
+				};
+
+				port@1 {
+					reg = <1>;
+					label = "lan1";
+					phy-handle = <&phy_port1>;
+				};
+
+				port@2 {
+					reg = <2>;
+					label = "lan2";
+					phy-handle = <&phy_port2>;
+				};
+
+				port@3 {
+					reg = <3>;
+					label = "lan3";
+					phy-handle = <&phy_port3>;
+				};
+
+				port@4 {
+					reg = <4>;
+					label = "lan4";
+					phy-handle = <&phy_port4>;
+				};
+
+				port@5 {
+					reg = <5>;
+					label = "wan";
+					phy-handle = <&phy_port5>;
+				};
+			};
+		};
+	};
