From: Alex Deucher Date: Fri, 27 Sep 2013 22:22:15 +0000 (-0400) Subject: drm/radeon: use hw generated CTS/N values for audio X-Git-Tag: firefly_0821_release~176^2~5079^2~11^2~10 X-Git-Url: http://demsky.eecs.uci.edu/git/?a=commitdiff_plain;h=ee0fec312a1c4e26f255955da942562cd8908a4b;p=firefly-linux-kernel-4.4.55.git drm/radeon: use hw generated CTS/N values for audio Use the hw generated values rather than calculating them in the driver. There may be some older r6xx asics where this doesn't work correctly. This remains to be seen.
