On the ThinkPad P71, we have one eDP connector exposed along with 5 DP connectors, resulting in a total of 11 TMDS encoders. Since the GPU on this system is also capable of MST, we create an additional 4 fake MST encoders for each DP port. Unfortunately, we also do this for the eDP port as well, resulting in: 1 eDP port: +1 TMDS encoder +4 DPMST encoders 5 DP ports: +2 TMDS

Currently, nouveau doesn't actually bother to try probing whether or not it can actually handle interlaced modes over DisplayPort. As a result, on volta and later we'll end up trying to set an interlaced mode even when it's not supported and cause the front end for the display engine to hang. So, let's teach nouveau to reject interlaced modes on hardware that can't actually

...->best_encoder is ignored both by the atomic modesetting helpers. That being said, this hook is completely broken anyway - it always returns the first msto for a given mstc, despite the fact it might already be in use. So, just get rid of it. We'll need this in a moment anyway, when we make mstos per-head as opposed to per-connector.
