+Binding for the Cadence USBSS-DRD controller
+
+Required properties:
+ - reg: Physical base address and size of the controller's register area.
+ - compatible: Should contain: "cdns,usb3"
+ - interrupts: Interrupt specifier. Refer to interrupt bindings.
+
+
+Example:
+ cdns3@f3000000 {
+ compatible = "cdns,usb3";
+ interrupts = <USB_IRQ 7 IRQ_TYPE_LEVEL_HIGH>;
+ reg = <0xf3000000 0x10000 //memory area for OTG/DRD registers
+ 0xf3010000 0x10000 //memory area for HOST registers
+ 0xf3020000 0x10000>; //memory area for Device registers
+ };
