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.
