Subject: [PATCH 2/3] drm/radeon: fix N/CTS clock matching for audio
The drm code that calculates the 1001 clocks rounds up
rather than truncating. This allows the table to match
properly on those modes.

Subject: [PATCH 3/3] 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.
