That's too much churn. Otherwise, please point me to driver code using the define (directly! that's the requirement). Best regards, Krzysztof

To get rid of all those macroes from dt-binding would mean to hardcode the interrupt number in both the binding example and in dtso, from this: interrupts = <RP1_INT_IO_BANK0 IRQ_TYPE_LEVEL_HIGH>, <RP1_INT_IO_BANK1 IRQ_TYPE_LEVEL_HIGH>, <RP1_INT_IO_BANK2 IRQ_TYPE_LEVEL_HIGH>; to this: interrupts = <0 IRQ_TYPE_LEVEL_HIGH>, <1 IRQ_TYPE_LEVEL_HIGH>, <2 IRQ_TYPE_LEVEL_HIGH>; is this what you are proposing?

Yes, just like every DTS does. I think the hard-coding of numbers is not a problem. Best regards, Krzysztof
