Sorry for the recent absence of activity on this patch series. I have the
sound card
working with alsa. The output works just fine. The input needs a little bit
of polishing to do.
To answer your question, it is still going to take some time because I
recently got selected
for an internship/mentorship program and I cannot give as much time to the
patch as I
would like to. It could still take me over a month to complete this.
Hope you understand.
(I've cc'd the mailing list and Gerd so that they too can know about this.)
Thanks,
Shreyansh Chouhan
