Tool used by maintainers and contributors to handle/send patches. See
korg docs (or just google "What is b4 Linux kernel").

Drop the tag everywhere and instead on the patches which were possible
to be tested mention how did you test it.

Tested means executing or parsing or using the code on the device under

I can read your patchsets and above does not proof how can you test binding.
