+Allwinner sun50i USB3 PHY
+-----------------------
+
+Required properties:
+- compatible : should be one of
+ * allwinner,sun60i-h6-usb3-phy
+- reg : a list of offset + length pairs
+- #phy-cells : from the generic phy bindings, must be 0
+- clocks : phandle + clock specifier for the phy clock
+- resets : phandle + reset specifier for the phy reset
+
+Optional nodes:
+- connector : A sub-node required for representing the connector connected
+ to the USB PHY. See ../connector/usb-connector.txt for details.
+
+Example:
+ usb3phy: phy@5210000 {
+ compatible = "allwinner,sun50i-h6-usb3-phy";
+ reg = <0x5210000 0x10000>;
+ clocks = <&ccu CLK_USB_PHY1>;
+ resets = <&ccu RST_USB_PHY1>;
+ #phy-cells = <0>;
+
+ connector {
+ compatible = "usb-a-connector";
+ label = "USB3";
+ };
+ };
