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.
