This firmware has been tested by LENOVO and DELL dmic machines, so far 
there is no issues found. And this firmware is not perfect, there are 
some features missing in this version like LED support and soundwire 
support,  and I am going to submit the new firmware Feb or Mar after 
Intel releases a new one to us, for now, the oem project push  me to 
submit this version first.


Thanks,

Hui.
