From 26f99321a04b01d59cedc434788830fd31b3c7d9 Mon Sep 17 00:00:00 2001 From: Alex Deucher Date: Fri, 27 Sep 2013 18:22:15 -0400 Subject: drm/radeon: use hw generated CTS/N values for audio commit ee0fec312a1c4e26f255955da942562cd8908a4b upstream. 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.
