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";

	};
