I don't understand and I do not see it explained, why do you remove
ADC7. The patch is also doing way too many things at the same time...

Bindings are always separate patches. If this is commit for bindings, then:

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.
