From: Alex Deucher Date: Wed, 12 Oct 2011 22:44:33 +0000 (-0400) Subject: drm/radeon/kms/DCE4.1: ss is not supported on the internal pplls X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=09cc6506f9e234b2ead60398ebb88c4b44421a93;p=openwrt%2Fstaging%2Fblogic.git drm/radeon/kms/DCE4.1: ss is not supported on the internal pplls It's handled via external clock. It should already be protected by the external ss flag, but add an explicit check just in case.
