From 9de88e6e89a2222061af8e1448f6f346e3413fc8 Mon Sep 17 00:00:00 2001 From: Adam Jackson Date: Tue, 12 Jul 2011 17:38:02 -0400 Subject: [PATCH] drm/i915/dp: Read more DPCD registers on connection probe For parity with radeon and nouveau, and also because I suspect we're going to need it to get format-conversion dongles right.
