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>;
