+Subject: drm/amdgpu/gfx9: switch to golden tsc registers for renoir+
+
+From: Alex Deucher <alexander.deucher@amd.com>
+
+commit 53af98c091bc42fd9ec64cfabc40da4e5f3aae93 upstream.
+
+Renoir and newer gfx9 APUs have new TSC register that is
+not part of the gfxoff tile, so it can be read without
+needing to disable gfx off.
