The main reason these can't go upstream is that it depends on knowing that we'll be able to fully control a PLL for HDMI and that's not guaranteed on upstream. I've tried to get folks interested in trying to solve that problem in the past but never made any real progress. :( In any case, if I can ever answer any questions about the HDMI configs I figured out to work on rk3288, please let me know. -Doug _______________________________________________ Linux-rockchip mailing list Linux-rockchip@xxxxxxxxxxxxxxxxxxx http://lists.infradead.org/mailman/listinfo/linux-rockchip
