virtuallization by allowing DMA jobs to be enqueued into different
command queues.

         Support the NXP Layerscape qDMA engine with command queue and legacy mode.

         Channel virtualization is supported through enqueuing of DMA jobs to,

         or dequeuing DMA jobs from, different work queues.

         This module can be found on NXP Layerscape SoCs.

	  The qdma driver only work on  SoCs with a DPAA hardware block.
