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

[PATCH v1 1/2] soc: ti: display firmware file name as part of boot log

[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.

Santosh, Arnd,
Could you please review and let me know if there is any comment. If
looks good, could you please merge to v4.4 next branch?
