Subject[PATCH 3.12 139/212] drm/radeon: adjust TN dpm parameters for stability (v2)
Date
3.12-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Alex Deucher <alexander.deucher@amd.com>

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
