+Subject: [PATCH 0099/2940] drm/amd/pp: OverDrive gfx domain voltage on Tonga
+
+Also ajust the gfx domain voltage on Tonga when user overdriver
+the voltage.
+
+For Tonga, Driver do not update user's setting to voltage table
+in smu, we only pick up a minimum value from voltage table that
+not less than the user's setting.
+
+v2: fix a typo
