1Maxim Integrated SPI-based USB 2.0 host controller MAX3421E
2
3Required properties:
4 - compatible: "maxim,max3421"
5 - spi-max-frequency: maximum frequency for this device must not exceed 26 MHz.
6 - reg: chip select number to which this device is connected.
7 - maxim,vbus-en-pin: <GPOUTx ACTIVE_LEVEL>
8   GPOUTx is the number (1-8) of the GPOUT pin of MAX3421E to drive Vbus.
9   ACTIVE_LEVEL is 0 or 1.
10 - interrupt-parent: the phandle of the associated interrupt controller.
11 - interrupts: the interuption line description for the interrupt controller.
12   The driver configures MAX3421E for active low level triggered interrupts,
13   configure your interrupt line accordingly.
