Subject: drm/radeon: adjust TN dpm parameters for stability (v2)
From: Alex Deucher <alexander.deucher@xxxxxxx>
commit 958b84fb3bef193198538b5c5902fa687cc8363f upstream.
Adjust some of the TN dpm settings for stability. Enabling
these features causes hangs and other stability problems
on certain boards.
v2: leave uvd dpm enabled
