[Intel-gfx] [PATCH 00/15] drm/i915: Expose margin connector properties for underscan

[Ville Syrjala]

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

Apparently some TVs suck and always overscan even when our infoframes
say that the image should be underscanned. Let's expose the (now
standard) margin properties to allow the user the compensate by
squishing the image down a bit via the panel fitter.

I've only implemented this for ilk+ because the old gmch panel fitter
is annoyingly limited. Also there is only one pfit on gmch platforms
(not counting the gm45 TV scaler -> pfit2 trick, which we don't even
support at the moment). SKL+ are also a bit limited by the number
of pipe scalers they have available for pfit vs. plane scaling, but
we'll leave that up to the usual atomic "-EINVAL -> try something
different" approach.
