I'm not sure we have a policy about describing hardware which can't be 
used without flipping switches. I have no opinion on if we should do 
that or not I leave that to others, but for the change itself.

I think it's good we describe it as it's part of the Draak board itself 
and not an expansion board which we have seen a lot of :-) Maybe even 
add a commented out line in the adv7612 port@2 which hints which VIN 
this is connected to if the switches are flipped?
