Yes, if you don't have time then I can take this. Since you have already
sorted out the pin definitions, it will be much easier.

Agree. But we both worked orthogonally and please let me know if you
find anything wrong with my approach.

What do you mean by fake pins for drive strength? All the pins are named
after the group name given in the datasheet. And I have already mentioned
in the binding that we can only do group access for these pins. There is
_no_way_ you can individually configure drive strength for the pins, if you
do then the entire group will get configured, does this makes sense?

Thanks,
Mani
