I doubt it.  I don't think the I2S standard allows for mono playback,
so the SSI would need to send the same sample twice, and I don't see
any support for that feature in the RM.

When I wrote fsl_ssi, I couldn't find any way to get mono playback to work.

BTW, I can't find the original patch in my inbox or the mailing list
archives.  When was it sent?
