Because it was misunderstood, here a longer answer.

You misunderstood the w/o documentation/bindings in a way that the full patch
set doesn't use it. But it means changes w/o these aspects...

That is true but not relevant at all since nobody wants to introduce platform_device
again.

I have just removed these from counting differences to make the number of
lines comparable to Rob's proposal.

Rob also uses device tree but has not added bindings or documentation to
his patch set so that it would be unfair to include them in the changes count in
one proposal and omit it in the other.

Generally it might not even be important to compare both approaches again
and then the number of files / changes is not important. But if it is, we should
count them correctly.
