Yeah my worry was all the DTB additions filter in would require a lot of 
coordination between the maintainers of all the different trees.

Having a few DONOTMERGE patches gave the driver maintainer a full look 
at the outcome of the series without having to worry about DTB conflicts 
when another tree picked something up, however I guess if everyone 
participates in -next it shouldn't be that big of a problem.
