[PATCH 0/4] sdvo hdmi regression fix and related cleanups

Hi all,

The first patch in this series fixes a long-standing hdmi-on-sdvo regression -
we apparently have not set up the pixel doubling (or quadrupling) correctly.
This regression was introduced in 2.6.36. Now if this patch is indeed correct,
hdmi on sdvo (and _only_ hdmi) for any pixelclock below 100 MHz should have been
broken since then. But we seem to have a decent lack of regression reports,
which is why I'm a bit uneasy with this patch.

So review, comments and especially testing (and tested-by gathering) on the
first patch highly welcome. I'd like to include this into -fixes for 3.4, but if
the testing/review on that patch is lacking, I'll postpone it for -next - it's
been broken for way too long anyway :(

The other patches are just clarifications and paranoia-checks for -next.

Yours, Daniel

Daniel Vetter (4):
  drm/i915: handle input/output sdvo timings separately in mode_set
  drm/i915: clarify preferred sdvo input mode code
  drm/i915: don't silently ignore sdvo mode_set failures
  drm/i915: debug messge for lossy sdvo dtd -> drm mode conversion
