This patch series enable accumulator queue support for K2 SoCs. Accumulator queues are a type of qmss queue that is monitored by the PDSP firmware and accumulated. Host is interrupted by PDSP firmware when packets become available in a ring buffer shared between the host and PDSP. There was an issue raised when merging the original patch set at (1) https://lkml.org/lkml/2015/9/4/681 [PATCH v1 1/2] soc: ti: display firmware file name as part of boot log (2) https://lkml.org/lkml/2015/9/4/680 [PATCH v1 2/2] ARM: dts: keystone: enable accumulator channels This series fixes the issues raised against above patch set. Key issues addressed. - Remove the firmware filename from DT and add it to the driver. Use a name ks2_qmss_pdsp_acc48.bin. The idea is this can be a soft link pointing to the real firmware file in file system. - Move the description of the driver design from DT document to one under Documentation/arm/keystone/knav-qmss.txt. Update the this document with location of acc firmware available under linux-firmware.git. Additionally added accumulator queue support optional so that lack of firmware in the file system will not cause other queue types not available due to driver probe failure.
