I still don't think that I understand :)

In snps,dw-pcie.yaml we currently (6.10-rc2) have:

const: legacy
(for the combined IRQ)

pattern: "^int(a|b|c|d)$"
(for the individual IRQs)

So we will need to support these indefinitely.

What is it that you would want to rename?

the combined irq?

Doesn't sound like a good idea to me, as we would need to support two
(perhaps that is what you meant).

But even if you wanted to rename it, it would be hard to come up with
a name. Perhaps intx, but that would be super confusing since we already
have inta, intb, intc, intd.

I think it is best just to not touch the binding.

In kernel macros could (that have already been renamed from legacy to intx)
doesn't really have anything to do with the DT binding IMO.


Kind regards,
Niklas
