From 77d8d00944dd5a0a2f4f67809819df927ee23030 Mon Sep 17 00:00:00 2001 From: Paulo Zanoni Date: Sat, 2 Nov 2013 21:07:45 -0700 Subject: [PATCH] drm/i915/bdw: check DPD on port D when setting the DDI buffers Use the eDP values on platforms where port D is eDP. This doesn't affect Haswell since it uses the same DDI buffer values for eDP and DP.
