- Maxim Integrated SPI-based USB 2.0 host controller MAX3421E
- Required properties:
- - compatible: Should be "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.
- - interrupts: the interrupt 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>;
- };
