Still not tested.

I repeated it multiple times. Please answer below, whether you
understand it:

Please use scripts/get_maintainers.pl to get a list of necessary people
and lists to CC. It might happen, that command when run on an older
kernel, gives you outdated entries. Therefore please be sure you base
your patches on recent Linux kernel.

You missed at least devicetree list (maybe more), so this won't be
tested by automated tooling. Performing review on untested code might be
a waste of time, thus I will skip this patch entirely till you follow
the process allowing the patch to be tested.

Please kindly resend and include all necessary To/Cc entries.

Other variants should be constrained to three items.

Actually that is not true: the number of interrupts depends on the
instance, not on the SoC.  The fourth interrupt is present on some
instances on other SoCs, too, but was never described before, as the
driver doesn't support it yet (I know this is not a good reason).
Of course none of this is obvious to the casual reviewer if it is
not mentioned in the patch description...

I'm working on making this more clear, and adding support for missing
variants.

Gr{oetje,eeting}s,

                        Geert
