Santosh Shilimkar 88139ed030 soc: ti: add Keystone Navigator DMA support ... The Keystone Navigator DMA driver sets up the dma channels and flows for the QMSS(Queue Manager SubSystem) who triggers the actual data movements across clients using destination queues. Every client modules like NETCP(Network Coprocessor), SRIO(Serial Rapid IO) and CRYPTO Engines has its own instance of packet dma hardware. QMSS has also an internal packet DMA module which is used as an infrastructure DMA with zero copy. Initially this driver was proposed as DMA engine driver but since the hardware is not typical DMA engine and hence doesn't comply with typical DMA engine driver needs, that approach was naked. Link to that discussion - https://lkml.org/lkml/2014/3/18/340 As aligned, now we pair the Navigator DMA with its companion Navigator QMSS subsystem driver.
