drm/radeon/kms: reorder display resume to avoid problems 2010-12-21T02:53:34+00:00 Alex Deucher alexdeucher@gmail.com 2010-12-20T16:22:29+00:00 a93f344d3c04e4b84490c65f2a574387c593be40 On resume, we were attemping to unblank the displays before the timing and plls had be reprogrammed which led to atom timeouts waiting for things that are not yet programmed. Re-program the mode first, then reset the dpms state. This fixes the infamous atombios timeouts on resume.
