soc: ti: knav_qmss_queue: change knav_range_setup_acc_irq to static

2015-01-29T21:23:51+00:00

knav_range_setup_acc_irq() is used only within the file and should
be defined as static.

soc: ti: knav_qmss_queue: makefile tweak to build as dynamic module

2015-01-29T21:23:51+00:00

Currently configuring qmss and dma as dynamic module creates three .ko
files. knav_qmss_acc.ko and knav_qmss_queue.ko both can't be insmod
because of circular dependency. So combine these two into one module
by changing the makefile.

soc: ti: knav_qmss_queue: export API calls for use by user driver

2015-01-29T17:04:26+00:00

Currently only few of the API calls are exported. This creates problem
when the knav* modules are built as modules and another user module
such as netcp_core try to use these API calls and they are also built
as module. This patch export these APIs to address the issue.

This is needed to support allmodconfig for ARM

Merge tag 'driver-core-3.19-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/driver-core

2014-12-15T00:10:09+00:00

Pull driver core update from Greg KH:
 "Here's the set of driver core patches for 3.19-rc1.

  They are dominated by the removal of the .owner field in platform
  drivers.  They touch a lot of files, but they are "simple" changes,
  just removing a line in a structure.

  Other than that, a few minor driver core and debugfs changes.  There
  are some ath9k patches coming in through this tree that have been
  acked by the wireless maintainers as they relied on the debugfs
  changes.

  Everything has been in linux-next for a while"

soc: ti: knav_qmss_queue: Use list_for_each_entry_safe to prevent use after free

2014-11-03T18:22:06+00:00

list_for_each_entry_safe() is necessary if list objects are deleted from
the list while traversing it.

soc: ti: Use list_first_entry_or_null() at appropriate places

2014-10-27T16:37:35+00:00

Use list_first_entry_or_null() for first_region() and first_queue_range().

list_first_entry() expects the list is not empty, so first_region() and
first_queue_range() never return NULL.
Thus use list_first_entry_or_null() instead.

soc: ti: add Keystone Navigator DMA support

2014-09-24T13:49:15+00:00

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.
