Also no, interrupt numbers are not considered bindings. That's too much
churn. Otherwise, please point me to driver code using the define
(directly! that's the requirement).

As mentioned above, RP1_INT_END is used in rp1-pci.c. To get rid of all those

Number of interrupts is not a binding, either. Does not appear in the DTS.

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
