This looks like a big mix of different changes and I don't see the relation 
between them.
To help facilitate the review process, I'd propose:
Any new binding with a new yaml file should be a single patch. Don't mix just 
adding one string with adding a new binding file in the same patch.

Split patch 9/9 into different patches, one for each driver. Otherwise it is 
nearly impossible to review such a big chunk of code.

Matthias
