That said, maybe a intermediate pinctrl approach might be more pragmatic and less theoretically flexible.
an option might be to "statically allocate" default number of interrupts to a domain - example:
* GIC IRQ 72->78 allotted to UARTs
* pinctrl mapping provided for those but only 6 can be used (rest are marked status="disabled" as default) at any given time (choice of pinctrl option determines GIC interrupt line to use)
* All modules will have a pinctrl definition to have a mapping - to avoid bootloader overriding default cross bar setting in ways un-expected by kernel.
Does that sound fair trade off?
This sounds better. That way we can get all the devices in the DT at least.
Fair enough - if Linus and Tony are still ok with this approach to the
problem, seeing a patch series with the effect would be beneficial.
