This patch series is built on top of ASoC git tree for-3.1 branch.
It will add the DMA use through dmaengine to the SSC/PCM Atmel drivers. These drivers are curently using the PDC DMA feature which has been replaced by a DMA controller in some chips. The dmaengine driver curently used is at_hdmac.
The first patch is a little update to wm8731 codec driver.
Nicolas Ferre (5): ASoC: wm8731: rework power management ASoC: atmel-ssc: add phybase in device structure ASoC: atmel-ssc: dmaengine usage switch depending on cpu ASoC: atmel_ssc_dai/atmel-pcm: adapt to dmaengine usage ASoC: atmel_ssc_dai: PM: actually stopping clock on suspend/resume
