How many times are we going to allow copy-and-pasting the same driver? Last time we wanted to modify the Rockchip driver, we were told "consolidate", because ST had already forked our driver. This nearly halted all progress. I'm going to be real disappointed if we see another fork get merged. (IOW, I would say "over my dead body," but I have no power here.) And why can't you use DRM? Brian
