From 5940ff3941c8917d04b1485e9ac9ae03da498393 Mon Sep 17 00:00:00 2001 From: Tyler DiBattista Date: Mon, 1 Apr 2019 15:20:44 -0400 Subject: [PATCH] drm/amd/display: Change Min fclk to 1.2Ghz [Why] Some nightly tests are failing since the new value for fclk is a bit too low. Also, a new test for the maximum downscale case was needed. [How] Updated the default value for fclk to be 1.2GHz.
