+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:
+ - HOST registers area
+ - DEVICE registers area
+ - OTG/DRD registers area
+ - reg-names - register memory area names:
+ "xhci" - for HOST registers space
+ "dev" - for DEVICE registers space
+ "otg" - for OTG/DRD registers space
+ - compatible: Should contain: "cdns,usb3"
+ - interrupts: Interrupts used by cdns3 controller:
+ "host" - interrupt used by XHCI driver.
+ "peripheral" - interrupt used by device driver
+ "otg" - interrupt used by DRD/OTG part of driver
+
+Optional properties:
+ - 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: from the *Generic PHY* bindings;
+ Supported names are:
+ - cdns3,usb2-phy
+ - cdns3,usb3-phy
+
+ - cdns,on-chip-buff-size : size of memory intended as internal memory for endpoints
+ buffers expressed in KB
+
+Example:
+ usb@f3000000 {
+ compatible = "cdns,usb3";
+ interrupts = <GIC_USB_IRQ 7 IRQ_TYPE_LEVEL_HIGH>,
+ <GIC_USB_IRQ 7 IRQ_TYPE_LEVEL_HIGH>,
+ <GIC_USB_IRQ 8 IRQ_TYPE_LEVEL_HIGH>;
+ interrupt-names = "host", "peripheral", "otg";
+ reg = <0xf3000000 0x10000>, /* memory area for HOST registers */
+ <0xf3010000 0x10000>, /* memory area for DEVICE registers */
+ <0xf3020000 0x10000>; /* memory area for OTG/DRD registers */
+ reg-names = "xhci", "dev", "otg";
+ phys = <&usb2_phy>, <&usb3_phy>;
