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

[Vova Barinov]

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.
