+Broadcom IPROC USB Device controller.
+
+The device node is used for UDCs integrated into Broadcom's
+iProc family (Northstar2, Cygnus) of SoCs'. The UDC is based
+on Synopsys Designware Cores AHB Subsystem Device Controller
+IP.
+
+Required properties:
+ - compatible: Add the compatibility strings for supported platforms.
+ For Broadcom NS2 platform, add "brcm,ns2-udc","brcm,iproc-udc".
+ For Broadcom Cygnus platform, add "brcm,cygnus-udc", "brcm,iproc-udc".
+ - reg: Offset and length of UDC register set
+ - interrupts: description of interrupt line
+ - phys: phandle to phy node.
+
+Example:
+ udc_dwc: usb@664e0000 {
+ compatible = "brcm,ns2-udc", "brcm,iproc-udc";
+ reg = <0x664e0000 0x2000>;
+ interrupts = <GIC_SPI 424 IRQ_TYPE_LEVEL_HIGH>;
+ phys = <&usbdrd_phy>;
