From 2e78416e763261fa8187429b7ea053d369fa7f79 Mon Sep 17 00:00:00 2001 From: Rodrigo Vivi Date: Tue, 5 Jan 2016 11:11:27 -0800 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8bit When debuging an intermittent corrupted screen I suspected on DDI translation table and checked we are out of date with the spec.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!
