From 018785ffb2b61e4cc7a9d66cf8b5796e598bec11 Mon Sep 17 00:00:00 2001 From: Alex Deucher Date: Wed, 31 Jul 2013 18:32:33 -0400 Subject: [PATCH] drm/radeon/dpm: fix spread spectrum setup Need to check for engine and memory clock ss separately and only enable dynamic ss if either of them are found. This should fix systems which have a ss table, but do not have entries for engine or memory. On those systems we may enable dynamic spread spectrum without enabling it on the engine or memory clocks which can lead to a hang in some cases.
