+* Qualcomm Atheros AR8xxx switch family
+
+Required properties:
+
+- compatible: should be "qca,ar8xxx"
+- dsa,mii-bus: phandle to the MDIO bus controller, see dsa/dsa.txt
+- dsa,ethernet: phandle to the CPU network interface controller, see dsa/dsa.txt
+- #size-cells: must be 0
+- #address-cells: must be 2, see dsa/dsa.txt
+
+Subnodes:
+
+The integrated switch subnode should be specified according to the binding
+described in dsa/dsa.txt.
+
+Optional properties:
+
+- qca,port6-phy-mode: if specified, the driver will configure Port 6 in the
+ given phy-mode. See Documentation/devicetree/bindings/net/ethernet.txt for
+ the list of valid phy-mode.
+
+- qca,port6-phy-id: if specified, the driver will connect Port 6 to the PHY
+ given as a parameter. In this case, Port6 and the corresponding PHY will be
+ isolated from the rest of the switch. From a system perspective, they will
+ act as a regular PHY.
+
+Example:
+
+ dsa@0 {
+ compatible = "qca,ar8xxx";
+ #address-cells = <2>;
+ #size-cells = <0>;
+
+ dsa,ethernet = <ðernet0>;
+ dsa,mii-bus = <&mii_bus0>;
+
+ switch@0 {
+ #address-cells = <1>;
+ #size-cells = <0>;
+ reg = <0 0>; /* MDIO address 0, switch 0 in tree */
+
+ qca,port6-phy-mode = "sgmii";
+ qca,port6-phy-id = <4>;
+
+ port@0 {
+ reg = <11>;
+ label = "cpu";
+ };
+
+ port@1 {
+ reg = <0>;
+ label = "lan1";
+ };
+
+ port@2 {
+ reg = <1>;
+ label = "lan2";
+ };
+
+ port@3 {
+ reg = <2>;
+ label = "lan3";
+ };
+
+ port@4 {
+ reg = <3>;
+ label = "lan4";
+ };
+ };
+ };
