USB xHCI controllers
|
||||
|
||||
Required properties:
|
||||
- compatible: should be "xhci-platform".
|
||||
- reg: should contain address and length of the standard XHCI
|
||||
register set for the device.
|
||||
- interrupts: one XHCI interrupt should be described here.
|
||||
|
||||
Example:
|
||||
usb@f0931000 {
|
||||
compatible = "xhci-platform";
|
||||
reg = <0xf0931000 0x8c8>;
|
||||
interrupts = <0x0 0x4e 0x0>;
|
||||
};
