You did not add any bindings. I don't understand this description.

Anyway, not tested.

<form letter>
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kernel, gives you outdated entries.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.

Tools like b4 or scripts/get_maintainer.pl provide you proper list of
people, so fix your workflow. Tools might also fail if you work on some
ancient tree (don't, instead use mainline) or work on fork of kernel
(don't, instead use mainline). Just use b4 and everything should be
fine, although remember about `b4 prep --auto-to-cc` if you added new
patches to the patchset.

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.

Please kindly resend and include all necessary To/Cc entries.
</form letter>


Best regards,
Krzysztof

My bad, extended the example for the interrupt controller node.
Will fix in the next version.

Understood. I didn't realize that yml goes through testing, thought it
was akin to a machine-readable portion of the documentation.

I used the "cached" version of the get_maintainers.pl output produced 
for v2. The bad assumption was that adding a yml do Documentation would 
not affect that. Will fix, appreciate helping me so much in getting this 
into a good shape!
