Hi Bill,
I have been working on the sam9263 AC97 driver. I have sent a patch to
the alsa mailing list but it has not being integrated yet (as far as I
know...)(http://mailman.alsa-project.org/pipermail/alsa-devel/2010-February/025119.html).
I have tested it and it worked, but I have recently made some changes so
the atmel ac97.c driver could support full duplex mode.
So I will submit a new patch by the end of the day/week, and I will copy
it to you if you are interested.
Regards,
Sedji Gaaouaou
