[RFC PATCH 00/13] audio support for at91sam9x5ek board

Hi,

Here is some work I've done to make the sound work on sam9x5ek.
It's based on Nicolas Ferre's and Uwe Kleine-König's work.
(Atmel patch on 2.6.39 if I recall)

I'd like to have some advice, mainly on the 1st patch
 "misc: atmel_ssc: add device tree DMA support".
I do not clearly see what is the right way to add DMA DT support for
this device, since it doesn't request a channel directly.


patches applies on next-20130701

[I let the original signed-off from Nicolas and Uwe in place, I don't
know if I should replace them by something like "originaly-signed-off-by"
since the code has been changed.]

Best regards,
Richard.
