Hi,
This series adds DT support for phycore-ac97 using the fsl-ssi driver. In version 2 I discarded most of the imx-ssi work and integrated the ac97-slave support in fsl-ssi, including support for imx-pcm-fiq as alternative to dma. There are some other changes to get phycore-ac97 working. The first two patches have notes about the detailed changes since version 1. The rest of the patches is new and necessary for the ac97-slave support.
Regards,

Hi,
The DMA PCM related changes won't apply anymore due to the recent dmaengine PCM cleanups. I've also been working on a more generic dmaengine PCM driver which has DT support and can be used by imx. The work in progress patches can be found here: https://github.com/lclausen-adi/linux-2.6/commits/asoc-dmaengine-cleanups

Okay, I will rebase it for v3 onto your committed cleanups and will have a look on your latest patches.
It might be a good idea to rebase it ontop of the generic dmaengine driver patches right away, since it will simplify things quite a bit.
I rebased the series onto your branch now. But there is a small problem with the DMA handling.
Currently you pass the device pointer into snd_dmaengine_pcm_register and use it to request the dma channels. At least for imx-pcm-audio driver, it would be useful to pass a second device just for the dma requests. Otherwise imx-pcm-audio needs devicetree bindings, but I think the dma properties belong to fsl-ssi.
I though about that as well, just initialize of_node of the newly allocated imx-pcm-audio platform device to that of the parent device. That should work nicely.
