I've just sent an in-depth review of patch 1/5 (sorry for being late). There 
are lots of small comments that could be addressed as follow-up patches in the 
worst case, but there's one comment regarding the ports DT property that 
worries me and that I'd like to see addressed (or, if I got it wrong, 
explained) before we merge this. Another related issue that I'd like to 
discuss is the need for the artificial xilinx-drm platform device. And of 
course if a v6 is needed, you can address all the other small comments :-)
