soc: ti: add Keystone Navigator QMSS driver 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: Documentation/devicetree/bindings/soc/keystone-navigator-qmss.txt Cc: Greg Kroah-Hartman <gregkh@linuxfoundation.org> Cc: Kumar Gala <galak@codeaurora.org> Cc: Olof Johansson <olof@lixom.net> Cc: Arnd Bergmann <arnd@arndb.de> Cc: Grant Likely <grant.likely@linaro.org> Cc: Rob Herring <robh+dt@kernel.org> Cc: Mark Rutland <mark.rutland@arm.com> Signed-off-by: Sandeep Nair <sandeep_n@ti.com> Signed-off-by: Santosh Shilimkar <santosh.shilimkar@ti.com> 2014-02-28 15:47:50 +00:00			`#`

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

soc: ti: Add wkup_m3_ipc driver Introduce a wkup_m3_ipc driver to handle communication between the MPU and Cortex M3 wkup_m3 present on am335x. This driver is responsible for actually booting the wkup_m3_rproc and also handling all IPC which is done using the IPC registers in the control module, a mailbox, and a separate interrupt back from the wkup_m3. A small API is exposed for executing specific power commands, which include configuring for low power mode, request a transition to a low power mode, and status info on a previous transition.
