[Intel-gfx] [PATCH 00/29] Haswell round 3

[Eugeni Dodonov]

Hi forks,

Just in time for everyone's weekend, here comes the 3rd round of patches on
Haswell.

As major highlights, it also adds support for HDMI/DVI outputs and multi-head
modes (I tried with VGA and HDMI).

Other than that, it is the same patches with comments from the past round
addressed (SBI locking support, proper WM calculation, better PCH items
detection, and so on).

Daniel, I think that the bits definitions, power wells, clocks programming, and
modesetting for both FDI and HDMI modes should be good to go unless someone
spots additional issues with them - so please, all of you who have something to
say about them, say it now and bikeshed as you please :).

Note that the DP and eDP modesetting support is not there yet - it will still
require a considerable amount of patches.

Also, there is one patch which fixes null pointer exceptions in gmbus code I
was having with some of the drm-intel-next-queued iterations, but I don't think
it is necessary at the moment now that gmbus stuff was disabled again (patch
5). I am not even sure if we'll hit those code paths with invalid values in
real life, so I simple added some checks for cases when we don't have a valid
adapter as it was looking too error-prone otherwise. Perhaps we could add a
WARN into them as well.
