DWC3

Required properties:

 - compatible: should be one of the following -

	       "samsung,exynos5250-dwusb3": for USB 3.0 DWC3 controller on

					    Exynos5250/5420.

	       "samsung,exynos5433-dwusb3": for USB 3.0 DWC3 controller on

					    Exynos5433.

	       "samsung,exynos7-dwusb3": for USB 3.0 DWC3 controller on Exynos7.

 - #address-cells, #size-cells : should be '1' if the device has sub-nodes

				 with 'reg' property.

 - ranges: allows valid 1:1 translation between child's address space and

	   parent's address space

 - clocks: Clock IDs array as required by the controller.

 - clock-names: Names of clocks corresponding to IDs in the clock property.

                Following clock names shall be provided for different

                compatibles:

                 - samsung,exynos5250-dwusb3: "usbdrd30",

                 - samsung,exynos5433-dwusb3: "aclk", "susp_clk", "pipe_pclk",

                                              "phyclk",

                 - samsung,exynos7-dwusb3: "usbdrd30", "usbdrd30_susp_clk",

                                           "usbdrd30_axius_clk"

 - vdd10-supply: 1.0V powr supply

 - vdd33-supply: 3.0V/3.3V power supply

Sub-nodes:

The dwc3 core should be added as subnode to Exynos dwc3 glue.

- dwc3 :

   The binding details of dwc3 can be found in:

   Documentation/devicetree/bindings/usb/snps,dwc3.yaml

Example:

	usb@12000000 {

		compatible = "samsung,exynos5250-dwusb3";

		clocks = <&clock 286>;

		clock-names = "usbdrd30";

		#address-cells = <1>;

		#size-cells = <1>;

		ranges;

		vdd10-supply = <&ldo11_reg>;

		vdd33-supply = <&ldo9_reg>;

		dwc3 {

			compatible = "synopsys,dwc3";

			reg = <0x12000000 0x10000>;

			interrupts = <0 72 0>;

			usb-phy = <&usb2_phy &usb3_phy>;

		};
