+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>;
