2018-04-18soc: ti: K2G: enhancement to support QMSS in K2G NAVSSMurali Karicheri1-1/+8
Navigator Subsystem (NAVSS) available on K2G SoC has a cut down version of QMSS with less number of queues, internal linking ram with lesser number of buffers etc. It doesn't have status and explicit push register space as in QMSS available on other K2 SoCs. So define reg indices specific to QMSS on K2G. This patch introduces "ti,66ak2g-navss-qm" compatibility to identify QMSS on K2G NAVSS and to customize the dts handling code. Per Device manual, descriptors with index less than or equal to regions0_size is in region 0 in the case of K2 QMSS where as for QMSS on K2G, descriptors with index less than regions0_size is in region 0. So update the size accordingly in the regions0_size bits of the linking ram size 0 register.

2017-12-06dt-bindings: Remove leading 0x from bindings notationMathieu Malaterre1-1/+1
Improve the binding example by removing all the leading 0x to fix the following dtc warnings: Warning (unit_address_format): Node /XXX unit name should not have leading "0x" Converted using the following command: find Documentation/devicetree/bindings -name "*.txt" -exec sed -i -e 's/([^ ])\@0x([0-9a-f])/$1\@$2/g' {} + This is a follow up to commit 48c926cd3414 Signed-off-by: Mathieu Malaterre <malat@debian.org> Signed-off-by: Rob Herring <robh@kernel.org>

2015-10-13soc: ti: add firmware file name as part of the driverMurali Karicheri1-1/+0
Currently firmware file name is included in the DTS. This is not scalable as user has to change the DTS if they need upgrade to a new firmware. Instead, add the firmware file name in the driver itself. As long as there is no API change, new firmware upgrade is easy and require no driver change. User is expected to copy the firmware image to the file system and add a sym link to the new firmware for doing an upgrade. Driver add a array of firmware file names to search for the available firmware blobs. This scheme also prepare the driver for future changes to API if ever happens. In such case it is assumed that driver needs to change to accommodate the new firmware and new firmware file name will get added to the array. Also update the DT document to remove the firmware attribute and add description about firmware in the driver documentation.

2014-09-24Documentation: dt: soc: add Keystone Navigator QMSS bindingsSandeep Nair1-0/+232
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.
