In general, you should try to do refactoring in a preparatory patch (one 
refactoring thing at a time) and add new stuff in another patch in 
the series. I didn't go to figure out how much it applies to those three 
items because you likely know the answer immediately.

> - Moved "generic rs485" support up in the file

Please do this in a separate patch.


Another general level problem with your series is that it adds functions 
x, y, etc. without users, whereas the expected way of doing things would 
be to add the functions in the change they are getting used so it's easier 
to follow what's going on.

I believe if you separate the refactoring & moving code around into own 
changes (no functional change type patches), the new stuff is much 
smaller so there is no need to split that illogically into incomplete 
fragments in some patches.
