From bda44c1ae7980c444814a50330f202c175de34ab Mon Sep 17 00:00:00 2001 From: Alex Deucher Date: Thu, 19 Dec 2013 12:03:35 -0500 Subject: [PATCH] drm/radeon/dpm: add late_enable for trinity Need to wait to enable cg and pg until after ring tests. Also make sure interrupts are enabled before we enable thermal interrupts.
