Subject: drm/radeon/dpm: adjust thermal protection requirements
X-Git-Tag: upstream/snapshot3+hdmi~4517^2~8^2~13
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=fda837241f3680e5dc554c26e178c2deec7a039c;p=platform%2Fadaptation%2Frenesas_rcar%2Frenesas_kernel.git

drm/radeon/dpm: adjust thermal protection requirements

On rv770 and newer, clock gating is not required
for thermal protection.  The only requirement is that
the design utilizes a thermal sensor.
