DMA is no required property anymore and uses the generic DMA bindings. imx-fiq is a new alternative to DMA Signed-off-by: Markus Pargmann --- Notes: Changes in v4: - Add a comment about hardware bugs for imx-pcm-fiq Changes in v3: - In previous versions, I removed fsl,playback-dma and capture-dma. But they are still in use by fsl_dma.c, so I added them again.
