[alsa-devel] Problems compiling Davinci ASoC driver in 2.6.26-rc6

[Kevin Hilman]

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.
