From: Libin Yang <libin.yang@linux.intel.com>

(This patch is developed by Dave Airlie <airlied@redhat.com> originally)

This patch adds support for DP MST audio in i915.

Enable audio codec when DP MST is enabled if has_audio flag is set.
Disable audio codec when DP MST is disabled if has_audio flag is set.

Another separated patches to support DP MST audio will be implemented
in audio driver.

This should be added after patch #3, since that's the one that fixes
enc_to_mst(). Otherwise:

Thanks Lyude. I realized that after sending the patches, will fix that.
