Maxim Integrated SPI-based USB 2.0 host controller MAX3421E



Required properties:

 - compatible: "maxim,max3421"

 - spi-max-frequency: maximum frequency for this device must not exceed 26 MHz.

 - reg: chip select number to which this device is connected.

 - maxim,vbus-en-pin: <GPOUTx ACTIVE_LEVEL>

   GPOUTx is the number (1-8) of the GPOUT pin of MAX3421E to drive Vbus.

   ACTIVE_LEVEL is 0 or 1.

 - interrupt-parent: the phandle of the associated interrupt controller.

 - interrupts: the interuption line description for the interrupt controller.

   The driver configures MAX3421E for active low level triggered interrupts,

   configure your interrupt line accordingly.



Example:



	usb@0 {

		compatible = "maxim,max3421";

		reg = <0>;

		maxim,vbus-en-pin = <3 1>;

		spi-max-frequency = <26000000>;

		interrupt-parent = <&PIC>;

		interrupts = <42>;

	};
