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.
Optional property:
- interrupt-parent: the phandle to the associated interrupt controller.
Example:
usb@0 {
compatible = "maxim,max3421";
reg = <0>;
maxim,vbus-en-pin = <3 1>;
spi-max-frequency = <26000000>;
interrupt-parent = <&PIC>;
interrupts = <42>;
};
