+* 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 {

+
+ #address-cells = <1>;
+ #size-cells = <0>;
