You need to add out endpoint It does comply with the bindings. The ports are all optional. As far as DT is concerned, the signal path ends here. This is also the final component _required_ to get the Linux kernel DRI up and running. > as well, and to do so you need to add bindings for eDP connector first > and then implement panel driver. > See Rob's suggestions here: http://patchwork.ozlabs.org/patch/1042593/ Well, one *could* extend the hardware description down to the actual panel if necessary, but on the Teres-I it is not. I assume the panel they ship provides proper EDID to the anx6345, because the display works fine here with this DT. Do I understand this correctly that the (3 different?) pinebook panels are not that easy to handle? I try to include the pinebook wherever possible, just because it's so similar, but here I'm a bit lost, so I had to omit these parts. Should I also have added a Tested-by: ? ;-) Torsten
