well, i sent patches for CPU support also. they are simply put on hold until
something is decided. if i were given a suggestion atleast i cud try doing that.
anyways, the machine driver will almost remain the same in future when we
the CPU support is there.

thank you. I didn't check full-duplex.

I did see for-2.6.33 tree but wasn't sure when i shud start submitting
against that.
It was only 2.6.32 when i started. And i tested playback/capture @ all
supported rates
in that version.
I am new to the process, please bear this time. Please reject a patch
and suggest how to do, if it's too much work for you.
Btw, I understand as soon as i see a newer for-2.6.xx branch i shud start
submitting against that. Right?
