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: aplay tone1KHzMono_8000.wav Playing WAVE 'tone1KHzMono_8000.wav' : Signed 16 bit Little Endian, Rate 8000 Hz, Mono davinci_pcm_prepare - 203 davinci_pcm_enqueue_dma - 77: period=2000,dma_offset=0,dma_pos=-2044854272
