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>;
};
