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.

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: ? ;-)
