Please use standard email subjects, so with the PATCH keyword in the
title. `git format-patch` helps here to create proper versioned patches.
Another useful tool is b4. Skipping the PATCH keyword makes filtering of
emails more difficult thus making the review process less convenient.

Please run scripts/checkpatch.pl and fix reported warnings. Some
warnings can be ignored, but the code here looks like it needs a fix.
Feel free to get in touch if the warning is not clear.

Best regards,
Krzysztof

Is there any reason to write QoS for the IPA before the IPA starts
poking around? The same question applies to aggre1 NoC.

Yes, as the NIUs require a clock source which may or may not be
the peripheral's clock
