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>;
|
|
};
