Merge remote-tracking branch 'takashi/topic/drm-sync-audio-rate' into drm-intel-next-queued
Pull in the i915/hda changes for N/CTS setting so I can apply the follow-up documentation work for drm/i915. Some conflicts because ofc we had to rework i915 while that N/CTS work was going on. But not more than adjacent changes really. Signed-off-by: Daniel Vetter <daniel.vetter@intel.com>
