+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 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 = <2600>;
+   interrupt-parent = <>;
+   interrupts = <42>;
+   };
