These drivers set the DMA_INTERRUPT capability bit when requesting a DMA controller channel. This was historical, and is no longer needed. Recent changes to the drivers/dma/fsldma.c driver have removed support for this flag. This makes the carma drivers unable to find a DMA channel with the required capabilities.
