+Binding for the Cadence USBSS-DRD controller
+
+Required properties:
+ - reg: Physical base address and size of the controller's register areas.
+ Controller has 3 different regions:
+ region 1 - HOST registers area
+ region 2 - DEVICE registers area
+ region 3 - OTG/DRD registers area
+ - compatible: Should contain: "cdns,usb3"
+ - interrupts: Interrupt specifier. Refer to interrupt bindings.
+ Driver supports only single interrupt line.
+ This single interrupt is shared between Device,
+ host and OTG/DRD part of driver.
+
+Optional propertiesi:
+ - maximum-speed : valid arguments are "super-speed", "high-speed" and
+ "full-speed"; refer to usb/generic.txt
+ - dr_mode: Should be one of "host", "peripheral" or "otg".
+ - phys: reference to the USB PHY
+ - phy-names: name of the USB PHY, should be "cdns3,usbphy"
+
+
+Example:
+ usb@f3000000 {
+ compatible = "cdns,usb3";
+ interrupts = <USB_IRQ 7 IRQ_TYPE_LEVEL_HIGH>;
+ reg = <0xf3000000 0x10000 //memory area for HOST registers
+ 0xf3010000 0x10000 //memory area for DEVICE registers
+ 0xf3020000 0x10000>; //memory area for OTG/DRD registers
+ };
