From 78e685f9a385eb984f69720e463878e5c3ae80b7 Mon Sep 17 00:00:00 2001 From: Wenjing Liu Date: Wed, 30 Aug 2017 17:49:39 -0400 Subject: [PATCH] drm/amd/display: Use TPS4 instead of CP2520_3 for phy pattern 7 [Description] We originally use TPS4 phy test pattern for test pattern 7. On RV we switched to a new method to use CP2520. CP2520 should produce the same result. However in reality, it fails DP PHY automation test. We use the original method instead.
