Subject: [PATCH] drm/i915: Update Skylake DDI translation table for HDMI.
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
When debuging an intermittent corrupted screen I suspected on DDI
translation table and checked we are out of date with the spec.
I'm not sure this will fix my bug yet, but it is always good to follow
the spec.
v2: Ville caught a switched i-boost value. Thanks!
