[PATCH v2 0/6] soc: ti: Add Keystone Navigator drivers

Here is an updated version of the Keystone Navigator drivers after
addressing comments from earlier version [1].

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.

I would like to get these drivers merged in upcoming(3.16) window, so
any help in terms of review is appreciated. Thanks
