[PATCH v3 00/10] drm/nouveau Enable HDMI Stereoscopy

[Alastair Bridgewater]

HDMI 3D mode support, round three.  Rebased to drm-next as it was on
Sunday morning.  Overall structure is the same as v2.

Substantially rewrote the first patch (nv50_head_atomic_check_mode())
since a recent change to the calculation of m->v.blankus caused a
merge conflict and problems with frame-packed and interlaced 3D modes,
and I found a much saner model for how the timing parameters work
while I was sorting that out.  Observable behavior changes from this
patch should be limited to better values for m->v.blankus on
interlaced non-doublescan modes and non-interlaced doublescan modes,
and some sort of effect on any mode with mode->vscan set (I don't know
if this case actually happens, but if it did then I would expect it to
have had some sort of problem in the previous implementation anyway).
Of the entire series, this first patch is more cleanup-and-bugfix than
anything else, and may be a candidate for merging early even if the
rest of the series is deferred until the next merge window.

Typo-busted the ninth patch (frame-packing geometry and timing) and
adjusted for the rename of drm_crtc_get_hv_timing() to
drm_mode_get_hv_timing().

Possibly some minor whitespace changes in one or two patches, plus
reformatted some of the patch comments.

Tested on my gt215 hardware only at this time, since I'm away from the
rest of my test hardware for about another week.  That said, all of
the changes are in the generic nv50 code, rather than being specific
to some chipset or family.

Thanks to Roy Spliet for assistance (mostly background information) in
working out what was going on with m->v.blankus.
