Yes, unfortunately the DaVinci ASoC changes were done based on DMA work that is not yet available in DaVinci git or mainline.
A month or so back, I posted to the davinci list saying I have a branch available where folks can play with ASoC until I get the DMA merge sorted out. That branch is here[1], but has not been updated to the latest asoc-dev tree.
Could you try to make it merged at least in the next kernel release?
thanks,

Hi, Vova
I've tried Davinci git tree and had the same compilation errors as with upstream 2.6.26-rc6.

Hi Freix,
I see that you use upstream kernel but you should use now davinci git tree that at 2.6.26-rc5. I'm not familiar with it's current status. Kevin Hilman is a maintainer and possible that he can answer about ASoC support there and about Davinci upstream status too. FYI: I can't see that Davinci DMA used in Davinci PCM is not in git tree. Not sure but possible that Kevin adapted ASoC for git DMA stuff. You can try the attached required patch that was sent to arm-linux mailing list some time ago and patch for i2c hack that is needed for Davinici but is not acceptable upstream.
Also I'm no more with MV. So have nothing access to h/w.

Are there plans to fix this before release of 2.6.26 ?
It looks like we are missing some DaVinci DMA definitions for audio. They are not anywhere in the current HEAD or in include/asm-arm/arch-davinci history.
Vladimir, is this something you could help with.
Thanks
