As far as I can tell the DU parallel output isn't used on the Eagle board, but 
is used on the Eagle expansion board. I would move this to patch 7/7 in this 
series.

These two properties should be moved to patch 7/7 too.

There's little use for enabling the DU in DT if you have no output port 
described. I'd move this to patch 6/7.
