Subject: [PATCH] drm/radeon/aux: fix hpd assignment for aux bus
Date: Tue, 22 Apr 2014 02:02:06 -0400 [thread overview]
Message-ID: <1398146526-9227-1-git-send-email-alexander.deucher@amd.com> (raw)
The hpd (hot plug detect) pin assignment got lost
in the conversion to to the common i2c over aux
code. Without this information, aux transactions
do not work properly. Fixes DP failures.
