[PATCH 00/22] drm/i915: Bigjoiner modeset sequence redesign and MST support

[Ville Syrjala]

From: Ville Syrjälä <ville.syrjala at linux.intel.com>

I started to look at the MST+bignoier stuff floating around
and then decided that there's just too much noise in the way,
and so did a quick pass over the whole thing to clean and
fix things up ahead of time.

I then applied the stuff from Stan and Vidya on top of what
I had and fixed it up enough to do a quick smoke test on my
ADL. It survived a 2x2 MST configuration with uncompressed
joiner enabled on both outputs. I don't have any DSC capable
hardware around so couldn't test bigjoiner.

Anyways, here's the whole pile for people to ruminate
over during Easter.

Also pushed it here:
