That looks like it went in in 2015, not 2010 - the commit date is in
March 2015, I suspect the 2010 date comes from whatever vendor tree it
came from. The code isn't super clear but it looks like a fairly
standard DSP streaming interface which should be supportable as a
compressed audio stream in ALSA (or regular one if the data is
uncompressed), there's no reason I can see for it to be done outside of
the standard audio framework.
