0001 Maxim Integrated SPI-based USB 2.0 host controller MAX3421E
0002
0003 Required properties:
0004  - compatible: Should be "maxim,max3421"
0005  - spi-max-frequency: maximum frequency for this device must not exceed 26 MHz.
0006  - reg: chip select number to which this device is connected.
0007  - maxim,vbus-en-pin: <GPOUTx ACTIVE_LEVEL>
0008    GPOUTx is the number (1-8) of the GPOUT pin of MAX3421E to drive Vbus.
0009    ACTIVE_LEVEL is 0 or 1.
0010  - interrupts: the interrupt line description for the interrupt controller.
0011    The driver configures MAX3421E for active low level triggered interrupts,
0012    configure your interrupt line accordingly.

0014 Example:
0015
0016         usb@0 {
0017                 compatible = "maxim,max3421";
0018                 reg = <0>;
0019                 maxim,vbus-en-pin = <3 1>;
0020                 spi-max-frequency = <26000000>;
0021                 interrupt-parent = <&PIC>;
0022                 interrupts = <42>;
0023         };
