Please see my comments on one of your previous versions; there are some patches due to be merged in 2.6.32 which change the board registration quite a bit. Take a look at Kevin's temp/asoc branch to see how the final merge will look.
Mark,
Should I create the patch against Kevin's temp/asoc branch?
Thanks,

Kevin,
Does the patch for DM365 EVM audio codec support should be created based on the current temp/asoc branch?
Thanks,
Miguel Aguilar

Probably, but Kevin's the one to ask here.
Miguel,
We have audio working on temp/asoc branch (patches from Chaithrika).
I think you should create the patches against temp/asoc (similar to the latest patches from Troy).
If you create it against temp/asoc, you will be able to test audio on DM365.
Thanks Sneha
