[Intel-gfx] [PATCH 00/15] high-bpp fixes and fdi auto dithering

[Daniel Vetter]

Hi all,

This fixes all the bugs I've found in my various systems when using non-24bpp
modes as the first part of the series.

And with working non-standard bpp support I've figured we can go fancy and
implemented auto-dithering if we hit an fdi bw limit. Which means that you can
now use 3-pipe pch configurations on ivb on pretty much everywhere. The only
restriction is that you need to fire up pipe C first, since without atomic
modeset pipe B will otherwise too much bw.

One big thing here is that this will break Paulo's hsw eDP machine, specifically
the patch called "drm/i915: force bpp for eDP panels". But apparently without
that my machine here is broken ... Ideas highly welcome about how we could quirk
ourselves out of this mess.

Cheers, Daniel
