...check the sink count and reprobe the connector if it's changed - something we don't actually do. As a result, nothing will happen if the user plugs the dongle in before plugging something into the dongle. So, let's fix this by checking the sink count in both nouveau_dp_probe_dpcd() and nouveau_dp_irq(), and reprobing the connector if things change.

To start off: this patch series is less work to review then it looks - most (but not all) of the nouveau related work has already been reviewed elsewhere. Most of the reason I'm asking for an RFC here is because this code pulls a lot of code out of i915 and into shared DP helpers. Anyway-nouveau's HPD related code has been collecting dust for a while. Other then the occasional runtime PM

Other then the occasional runtime PM related and MST related fixes, we're missing a lot of nice things that have been added to DRM since this was originally written. Additionally, the code
