Uh, accept my apologies. I know exactly how it feels ;-)

Ah, I see. You should have included the binding documentation in the
driver using the bindings, not in the patch adding the required nodes to
DTS files... Than no one would have any comments on this patch ;-)

So yes, if the driver part got merged I will shut up now, providing you
promise to work on "consolidating" the bindings for the next cycle. The
sooner, the better. Does it sound like a deal?
