-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>;
-		phy-names = "cdns3,usb2-phy", "cnds3,usb3-phy";
-	};
