+HiSilicon INNO USB2 PHY
+-----------------------
+Required properties:
+- compatible: Should be one of the following strings:
+		"hisilicon,inno-usb2-phy",
+		"hisilicon,hi3798cv200-usb2-phy",
+- #phy-cells: Shall be 0.
+- hisilicon,peripheral-syscon: Phandle of syscon used to control phy.
+- hisilicon,phycon-reg: Offset of the phy control register in the syscon.
+- hisilicon,port-num: Number of utmi ports. Range [1,2].
+- clocks: Phandle and clock specifier pair for reference clock utmi_refclk.
+- resets: List of phandle and reset specifier pairs for each reset signal
+in reset-names.
+- reset-names: Shall be "power_on", "utmi0", "utmi1". Thereinto, utmi[n] is
+required only if port[n] exists.
+
+Refer to phy/phy-bindings.txt for the generic PHY binding properties
+
+Example:
+usb2_phy: phy {
+		 compatible = "hisilicon,inno-usb2-phy";
+		 #phy-cells = <0>;
+		 hisilicon,peripheral-syscon = <&peri_ctrl>;
+		 hisilicon,phycon-reg = <0x120>;
+		 hisilicon,port-num = <2>;
+		 clocks = <&crg USB2_PHY_UTMI_REF_CLK>;
+		 resets = <&crg 0xbc 2>,
+			  <&crg 0xbc 8>,
+			  <&crg 0xbc 9>,
+		 reset-names = "power_on", "utmi0", "utmi1";
+	 };
