While testing Qualcomm soundwire controller version 1.5.1, found two issue,
Firstly the frame shape information configured vs the bus parameters
are out of sync. secondly some ports on this ip version require
block packing mode support.
With this two patches on top of https://lkml.org/lkml/2020/9/5/220
("[PATCH v2 0/4] soundwire: qcom: add support for mmio soundwire master")
patchset I was able to test 2 WSA speakers!
This patchset depends on this above patchset!
thanks,
srini
