After looking at the Bugzilla it looks like you are looking for something
else.

Recent Intel platforms contains HD Audio controllers with Integrated 
DSPs. Intel releases firmware which runs on this DSPs. You can connect
various codecs e.g. I2S, HDA etc. Support for I2S based codecs is
already available in the kernel today. However support for HDA codecs
connected via DSP is not yet upstreamed. I am trying to do it.

In your case the DSP functionality is part of the Maxim HDA codec.
My work is to enable the DSP functionality on the Intel SoC. So it
may not help you directly.
