From fda837241f3680e5dc554c26e178c2deec7a039c Mon Sep 17 00:00:00 2001 From: Alex Deucher Date: Wed, 31 Jul 2013 12:41:35 -0400 Subject: [PATCH] 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.
