[ 083/120] drm/radeon: only adjust default clocks on NI GPUs
From: Greg Kroah-Hartman
Date: Wed Oct 10 2012 - 21:26:12 EST
3.4-stable review patch. If anyone has any objections, please let me know.
------------------
From: Alex Deucher <alexander.deucher@xxxxxxx>
commit 2e3b3b105ab3bb5b6a37198da4f193cd13781d13 upstream.
SI asics store voltage information differently so we
don't have a way to deal with it properly yet.
