From c8908f579ae9aac33122cfdfffaef30bba0a7697 Mon Sep 17 00:00:00 2001 From: Alex Deucher Date: Fri, 27 Sep 2013 18:19:42 -0400 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.
