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.



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>;

	};
