+If Tsi721 mport driver have been built with RAPIDIO_DMA_ENGINE support included,
+this driver will accept DMA-specific module parameter:
+  "dma_desc_per_channel" - defines number of hardware buffer descriptors used by
+                           each BDMA channel of Tsi721 (by default - 128).

 IV. Version History

+  1.1.0 - DMA operations re-worked to support data scatter/gather lists larger
+          than hardware buffer descriptors ring.
  1.0.0 - Initial driver release.
