Hello!
About two years ago Johannes Berg wrote support for the PowerMac3,6 aka G4 MDD
which I was using as a desktop computer then. Johannes wrote all the code, and
I tested it.
I now have a PowerMac3,5 – yes, an earlier model.
This patch makes the snd-aoa ALSA sound module support the TAS3001C codec of
my Apple Power Mac G4 "Quicksilver" (2001 model). I suppose it will also work
for the "Quicksilver 2002", since both identify as PowerMac3,5.
The patch also changes a few comments to name the exact Power Mac model more
accurately in sound/aoa/fabrics/layout.c.
This is my first contribution to the linux kernel ever, so I hope you will be
kind to me. I am not a programmer, but adding already supported devices was a
task even I could accomplish.
Thanks,
Andreas aka Linux User #330250
