- 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>;
- };
- 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.
- Example:
- usb@12120000 {
- compatible = "samsung,exynos4210-ohci";
- reg = <0x12120000 0x100>;
- interrupts = <0 71 0>;
- };
