Subject: [PATCH 5/6] DT bindings documentation for Broadcom IPROC USB Device controller.

The device node is used for UDCs integrated into Broadcom's
iProc family of SoCs'. The UDC is based on Synopsys Designware
Cores AHB Subsystem USB Device Controller IP.

+Broadcom IPROC USB Device controller.
+
+The device node is used for UDCs integrated into Broadcom's
+iProc family of SoCs'. The UDC is based on Synopsys Designware
+Cores AHB Subsystem Device Controller.
+
+Required properties:
+ - compatible: should be "brcm,iproc-snps-udc"
+ - reg: Offset and length of UDC register set
+ - interrupts: description of interrupt line
+ - phys: phandle to phy node.
+ - extcon: phandle to the extcon device. This is optional and
+   not required for those that don't require extcon support.
+   Extcon support will be required if the UDC is connected to
+   a Dual Role Device Phy that supports both Host and Device
+   mode based on the external cable.
+
+Example:
+	udc_dwc: usb@...e0000 {
+		compatible = "brcm,iproc-snps-udc";
+		reg = <0x664e0000 0x2000>;
+		interrupts = <GIC_SPI 424 IRQ_TYPE_LEVEL_HIGH>;
+		phys = <&usbdrd_phy>;
+		extcon = <&usbdrd_phy>";
