[alsa-devel] ASoC: Davinci Voice codec compliant to arago kernel for dm365

[Raffaele Recalcati]

Hi Miguel,
I've used successfully the patches below on top of 2.6.34 Kevin Hilman
kernel for davinci
http://git.kernel.org/pub/scm/linux/kernel/git/khilman/linux-davinci.git

Now I need to backport your patches to arago kernel
http://arago-project.org/git/projects/linux-davinci.git
that means 2.6.32-rc1
I use able adapt your patches to it, but I guess that there are many changes
from 2.6.32-rc1 to 2.6.34 ...
Can you tell me what is the best thing to do?
I'm afraid you'll tell me that I need to rewrite completely your patches to
be really compliant to 2.6.32-rc1.

Here you are a not working log:
