I haven't had time to test further, but with all 5 applied on top of 
deathsimple drm-fixes I loose output to TV as soon as I startx.

It worked in fbcon before starting X, but not switching vt after.

My TV according to edid-decode does support deep colour.

Nothing obvious to see in dmesg/Xorg.0.log and xrandr --verbose looked 
like it was on, tried some different modes, but nothing.
