From 092945e11c5b84f66dd08f0b87fb729715d377bc Mon Sep 17 00:00:00 2001 From: Adam Jackson Date: Tue, 26 Jul 2011 15:39:45 -0400 Subject: [PATCH] drm/i915/dp: Use auxch precharge value of 5 everywhere The default in the Sandybridge docs is 5, as on Ironlake, and I have no reason to believe 3 would work any better.
