Please use subject prefixes matching the subsystem. You can get them for
example with `git log --oneline -- DIRECTORY_OR_FILE` on the directory
your patch is touching. For bindings, the preferred subjects are
explained here:
https://www.kernel.org/doc/html/latest/devicetree/bindings/submitting-patches.html#i-for-patch-submitters

Please order the patchset as expressed in submitting patches DT
document. Or SoC maintainer profile.


Best regards,
Krzysztof

Got it. I will revise the subject according to the doc.

OK, I will ensure the patchset is ordered properly in the next patch
