+Synopsys USB Device controller.
+
+The device node is used for Synopsys Designware Cores AHB
+Subsystem Device Controller (UDC).
+
+Required properties:
+ - compatible: should be "snps,dw-ahbudc"
+ - reg: Offset and length of UDC register set
+ - interrupts: description of interrupt line
+ - phys: phandle to phy node.
+ - phy-names: name of phy node. Must be usb2drd.
+ - extcon: phandle to the extcon device
+
+Example:
+
+ usbdrd_phy: phy@...1c000 {
+ #phy-cells = <0>;
+ compatible = "brcm,ns2-drd-phy";
+ reg = <0x66000000 0x1000>,
+ }
+
+ udc_dwc: usb@...e0000 {
+ compatible = "snps,dw-ahb-udc";
+ reg = <0x664e0000 0x2000>;
+ interrupts = <GIC_SPI 424 IRQ_TYPE_LEVEL_HIGH>;
+ phys = <&usbdrd_phy>;
+ phy-names = "usb2drd";
+ extcon = <&usbdrd_phy>";
+ };
