      drivers/soc: ti: fix build break with modules · b2fc3f3c
      Olof Johansson authored 
      Fixes below build break by not switching to stubs when the driver is a module:

drivers/soc/ti/knav_dma.c:418:7: error: redefinition of 'knav_dma_open_channel'
 void *knav_dma_open_channel(struct device *dev, const char *name,
       ^

Merge "soc: Keystone SOC Navigator drivers for 3.18" from Santosh Shilimkar:

Keystone SOC Navigator drivers for 3.18

The Keystone Multi-core Navigator contains QMSS and packet DMA
subsystems which interwork together to form the Navigator cloud
used by various subsystems like NetCP, SRIO, SideBand Crypto
engines etc.

      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.

      Sandeep Nair authored 
      The QMSS (Queue Manager Sub System) 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
Packet DMA.

The Queue Manager is a hardware module that is responsible for accelerating
management of the packet queues. Packets are queued/de-queued by writing or
reading descriptor address to a particular memory mapped location. The PDSPs
perform QMSS related functions like accumulation, QoS, or event management.
Linking RAM registers are used to link the descriptors which are stored in
descriptor RAM. Descriptor RAM is configurable as internal or external memory.

The QMSS driver manages the PDSP setups, linking RAM regions,
queue pool management (allocation, push, pop and notify) and descriptor
pool management. The specifics on the device tree bindings for
QMSS can be found in:

Merge "omap intc changes for v3.18 merge window" from Tony Lindgren:

Interrupt code related clean-up for omap2 and 3 to make
it ready to move to drivers/irqchip. Note that this series
does not yet move the interrupt code to drivers, that will
be posted separately as a follow-up series.

Note that this branch has a dependency to patches both
in fixes-v3.18-not-urgent and soc-for-v3.18 and is based on
a merge. Without doing the merge, off-idle would not work
properly for git bisect.
