+* Qualcomm Atheros QCA8xxx switch family
+
+Required properties:
+
+- compatible: should be "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.
+
+Example:
+
+ &mdio0 {
+ switch@0 {
+ compatible = "qca,qca8337";
+
+ #address-cells = <1>;
+ #size-cells = <0>;
+ reg = <30>;
+
+ ports {
+ port@0 {
+ reg = <11>;
+ label = "cpu";
+ ethernet = <&gmac1>;
+ phy-mode = "rgmii";
+ };
+
+ port@1 {
+ reg = <0>;
+ label = "lan1";
+ };
+
+ port@2 {
+ reg = <1>;
+ label = "lan2";
+ };
+
+ port@3 {
+ reg = <2>;
+ label = "lan3";
+ };
+
+ port@4 {
+ reg = <3>;
+ label = "lan4";
+ };
The <unit-address> part of the node name should correspond to the "reg"
prop. I think modern 'dtc' even warns about that...
