sorry this took a bit longer, but I can confirm that the 4 relevant
patches (1, 4, 5, 6) at least still provide 1080p hdmi output on
rk3288 (with internal hdmiphy) and rk3328 (with external innosilicon
hdmiphy). I don't know how to test newly added features, but at
least the patches don't seem to break existing users, so

on rk3288 and rk3328
