+* Atheros AR71XX/9XXX USB PHY
+
+Required properties:
+- compatible: "qca,ar7100-usb-phy"
+- #phys-cells: should be 0
+- reset-names: "usb-phy"[, "usb-suspend-override"]
+- resets: references to the reset controllers
+
+Example:
+
+ usb-phy {
+ compatible = "qca,ar7100-usb-phy";
+
+ reset-names = "usb-phy", "usb-suspend-override";
+ resets = <&rst 4>, <&rst 3>;
+
+ #phy-cells = <0>;
+ };
