UDC



Required properties:

 - compatible: Should be "marvell,pxa270-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:



		pxa27x_udc: udc@40600000 {

			compatible = "marvell,pxa270-udc";

			reg = <0x40600000 0x10000>;

			interrupts = <11>;

			clocks = <&pxa2xx_clks 11>;

			gpios = <&gpio 22 GPIO_ACTIVE_LOW>;

		};
