From 3819e8844d83b181f99af758ebaba2974fef2ebc Mon Sep 17 00:00:00 2001
From: Evan Quan <evan.quan@amd.com>
Date: Wed, 20 Feb 2019 16:40:47 +0800
Subject: [PATCH 1324/2940] drm/amd/powerplay: overwrite ODSettingsMin for
UCLK_FMAX feature
For UCLK_FMAX OD feature, SMU overwrites the highest UCLK DPM level freq.
Therefore it can only take values that are greater than the second highest
DPM level freq.
