I'm not the maintainer, but I find this approach to the pins
really annoying. I have to flip to another file to figure out how
a board has configured the pins. And we may bring in a bunch of
settings that we don't ever use on some board too. Why can't we
put the settings in the board file directly?

I'd expect some sort of serial alias node stuff here too.

Is this binding still being reviewed? Ugly.

Why at the bottom?
