1Maxim Integrated SPI-based USB 2.0 host controller MAX3421E 2 3Required properties: 4 - compatible: Should be "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 - interrupts: the interrupt line description for the interrupt controller. 11 The driver configures MAX3421E for active low level triggered interrupts, 12 configure your interrupt line accordingly. 13 14Optional property: 15 - interrupt-parent: the phandle to the associated interrupt controller. 16 17Example: 18 19 usb@0 { 20 compatible = "maxim,max3421"; 21 reg = <0>; 22 maxim,vbus-en-pin = <3 1>; 23 spi-max-frequency = <26000000>; 24 interrupt-parent = <&PIC>; 25 interrupts = <42>; 26 }; 27
