+PXA25x UDC (USB Device Controller)
+
+The PXA25x and IXP4xx USB Device Controller is different from the
+PXA27x UDC described in pxa-usb.txt and is compatible between the
+Marvell PXA25x and the Intel IXP4xx devices.
+
+Required properties:
+ - compatible: Should be one of
+ "marvell,pxa25x-udc"
+ "intel,ixp4xx-udc"
+ for USB controllers used in device mode.
+ - reg: usb device MMIO address space
+ - interrupts: single interrupt generated by the UDC IP
+ - clocks: input clock of the UDC IP (see clock-bindings.txt)
+
+Optional properties:
+ - gpios:
+ - gpio activated to control the USB D+ pullup (see gpio.txt)
+
+Example:
+
+usb@c800b000 {
+ compatible = "intel,ixp4xx-udc";
+ reg = <0xc800b000 0x1000>;
+ interrupts = <12 IRQ_TYPE_LEVEL_HIGH>;
+ clocks = <&pclk 0>;
+};
