Let me try to understand if the dependency is true.

Saying I apply the DTS patch on IMX tree while Mark apply the fsl_ssi
patch on his tree, will there be any regression on either IMX tree or
Mark's tree?  The monaural playback on imx6qdl never worked, so it's not
a regression.  If there is no regression on either tree, there is no
dependency to maintain.
