Subject: [PATCH v5 2/5] dt-bindings: phy: add binding for Allwinner USB3 PHY
Date:   Sat,  6 Apr 2019 04:57:33 +0800

Precedence: bulk

The new Allwinner H6 SoC contains a USB3 PHY that is wired to the
external USB3 pins of the SoC.

Add a device tree binding for the PHY.

+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";
+		};
+	};
