+* ROCKCHIP type-c PHY
+---------------------
+
+Required properties:
+ - compatible: should be "rockchip,rk3399-typec-phy0" or
+			 "rockchip,rk3399-typec-phy1"
+ - reg : Address and length of the usb phy control register set
+ - rockchip,grf : phandle to the syscon managing the "general
+   register files"
+ - clocks : phandle + clock specifier for the phy clocks
+ - clock-names: string, clock name, must be "tcpdcore", "tcpdphy_ref";
+ - resets : a list of phandle + reset specifier pairs
+ - reset-names : string reset name, must be:
+		 "tcphy", "tcphy_pipe", "uphy_tcphy"
+ - #phy-cells: Must be 0.  See ./phy-bindings.txt for details.
+ - extcon: extcon specifier for the Power Delivery
+
+Example:
+	tcphy0: phy@...c0000 {
+		compatible = "rockchip,rk3399-typec-phy0";
+		reg = <0x0 0xff7c0000 0x0 0x40000>;
+		#phy-cells = <0>;
+		extcon = <&fusb1>;
+		rockchip,grf = <&grf>;
+		clocks = <&cru SCLK_UPHY0_TCPDCORE>,
+			 <&cru SCLK_UPHY0_TCPDPHY_REF>;
+		clock-names = "tcpdcore", "tcpdphy_ref";
+		resets = <&cru SRST_UPHY0>,
+			 <&cru SRST_UPHY0_PIPE_L00>,
+			 <&cru SRST_P_UPHY0_TCPHY>;
+		reset-names = "tcphy", "tcphy_pipe", "uphy_tcphy";
+	};
+
+	tcphy1: phy@...00000 {
+		compatible = "rockchip,rk3399-typec-phy1";
+		reg = <0x0 0xff800000 0x0 0x40000>;
+		#phy-cells = <0>;
+		rockchip,grf = <&grf>;
+		clocks = <&cru SCLK_UPHY1_TCPDCORE>,
+			 <&cru SCLK_UPHY1_TCPDPHY_REF>;
+		clock-names = "tcpdcore", "tcpdphy_ref";
+		resets = <&cru SRST_UPHY1>,
+		         <&cru SRST_UPHY1_PIPE_L00>,
+			 <&cru SRST_P_UPHY1_TCPHY>;
+		reset-names = "tcphy", "tcphy_pipe", "uphy_tcphy";
+	};
