Here is an updated version3 of the Keystone Navigator drivers after addressing Rob's device tree bindings comments from earlier version [1]. I couldn't get the series ready just in time for v3.17 merge window but surely like to get it in v3.18 merge window. The QMSS found on Keystone SOCs is one of the main hardware sub system which forms the backbone of the Keystone Multi-core Navigator. QMSS consist of queue managers, packed-data structure processors(PDSP), linking RAM, descriptor pools and infrastructure DMA. After the discussion and alignment [2] on Navigator DMA, now we pair this driver along with QMSS. Initially this driver was proposed as DMA engine driver but since the hardware is not typical DMA engine and doesn't comply with typical DMA engine driver needs, that approach was naked. These two drivers works as infrastructure drivers for subsystems like Ethernet subsystem, SRIO subsystem, Crypto Engines etc on Keystone SOC families. Testing is done with NetCP(ethernet) subsystem drivers.
