[Intel-gfx] [PATCH 0/4] drm/i915: Trust VBT aux/ddc information

[ville.syrjala at linux.intel.com]

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

So we have a bug or two ([1] at least) about using an incorrect gmbus pin for
a HDMI connector. So I cooked up some patches to expand our use of VBT for this
information. So far I've kept it limited to DDI platforms, but I think I've seen
another bug about CHV using the incorrect gmbus pin as well, not 100% sure though.

I slapped cc:stable on them since they do fix an actual issue. My track record
with this sort of firmware information hasn't been great as of late, so some
fallout might occur.


Anyways here's the entire series:
