-Samsung Exynos SoC USB controller
-
-The USB devices interface with USB controllers on Exynos SOCs.
-The device node has following properties.
-
-EHCI
-Required properties:
- - compatible: should be "samsung,exynos4210-ehci" for USB 2.0
-   EHCI controller in host mode.
- - reg: physical base address of the controller and length of memory mapped
-   region.
- - interrupts: interrupt number to the cpu.
- - clocks: from common clock binding: handle to usb clock.
- - clock-names: from common clock binding: Shall be "usbhost".
- - phys: from the *Generic PHY* bindings; array specifying phy(s) used
-   by the root port.
- - phy-names: from the *Generic PHY* bindings; array of the names for
-   each phy for the root ports, must be a subset of the following:
-   "host", "hsic0", "hsic1".
-
-Optional properties:
- - samsung,vbus-gpio:  if present, specifies the GPIO that
-   needs to be pulled up for the bus to be powered.
-
-Example:
-
-	usb@12110000 {
-		compatible = "samsung,exynos4210-ehci";
-		reg = <0x12110000 0x100>;
-		interrupts = <0 71 0>;
-		samsung,vbus-gpio = <&gpx2 6 1 3 3>;
-
-		clocks = <&clock 285>;
-		clock-names = "usbhost";
-
-		phys = <&usb2phy 1>;
-		phy-names = "host";
-	};
-
-OHCI
-Required properties:
- - compatible: should be "samsung,exynos4210-ohci" for USB 2.0
-   OHCI companion controller in host mode.
- - reg: physical base address of the controller and length of memory mapped
-   region.
- - interrupts: interrupt number to the cpu.
- - clocks: from common clock binding: handle to usb clock.
- - clock-names: from common clock binding: Shall be "usbhost".
- - phys: from the *Generic PHY* bindings; array specifying phy(s) used
-   by the root port.
- - phy-names: from the *Generic PHY* bindings; array of the names for
-   each phy for the root ports, must be a subset of the following:
-   "host", "hsic0", "hsic1".
-
-Example:
-	usb@12120000 {
-		compatible = "samsung,exynos4210-ohci";
-		reg = <0x12120000 0x100>;
-		interrupts = <0 71 0>;
-
-		clocks = <&clock 285>;
-		clock-names = "usbhost";
-
-		phys = <&usb2phy 1>;
-		phy-names = "host";
-	};
-
-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>;
-		};
