From 8409360381ebaaab82c7ab502665a29423fcdfc2 Mon Sep 17 00:00:00 2001 From: Daniel Vetter Date: Fri, 1 Nov 2013 10:50:21 +0100 Subject: [PATCH] drm/i915: scramble reset support for DP port CRC on g4x We need to reset the DP scrambler on every vsync to get stable CRCs. And since we can't use the normal pipe CRC on DP ports on g4x we really need them to be able to test modesetting issues on (e)DP outputs. Note that the DC balance reset is for SDVO port CRCs so we don't strictly need it. But better safe than sorry (and it's a nice template in case we ever want to grab port CRCs for e.g. audio checking). v2: Apply the suggestions from Damien's review.
