Nope, wrong flag. This is a hint for us that you based your DTS on
something ancient (e.g. broken downstream stuff). Please start from
*scratch* and write your DTS based on a board taken from mainline.
There is no point for us to repeat review for all the things we already
fixed in mainline.

Node names should be generic.
