From 41f93af900a20d1a0a358b522b5129c89677e9dc Mon Sep 17 00:00:00 2001 From: Sandeep Nair Date: Fri, 28 Feb 2014 10:47:50 -0500 Subject: 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 Cc: Kumar Gala Cc: Olof Johansson Cc: Arnd Bergmann Cc: Grant Likely Cc: Rob Herring Cc: Mark Rutland Signed-off-by: Sandeep Nair Signed-off-by: Santosh Shilimkar --- drivers/Kconfig | 2 ++ 1 file changed, 2 insertions(+) (limited to 'drivers/Kconfig') diff --git a/drivers/Kconfig b/drivers/Kconfig index 622fa266b29e..1a693d3f9d51 100644 --- a/drivers/Kconfig +++ b/drivers/Kconfig @@ -148,6 +148,8 @@ source "drivers/remoteproc/Kconfig" source "drivers/rpmsg/Kconfig" +source "drivers/soc/Kconfig" + source "drivers/devfreq/Kconfig" source "drivers/extcon/Kconfig" -- cgit v1.2.3-55-g7522
