[RFC,00/12] soundwire/SOF: updated interfaces, functional integration

Message

Pierre-Louis Bossart Sept. 16, 2019, 9:42 p.m. UTC

This series builds on the 'soundwire: add Master device support,
GreyBus style' RFC'. It provides enhancements to the stream callbacks,
a split initialization. Most of the SOF patches were already submitted
in an earlier RFC, and feedback on the parameters was taken into
account. The main change here are the API changes with a split between
ACPI scan, probe, startup steps.


Known limits:
a) Power management (regular suspend/resume and pm_runtime) is not
supported for now as we need to run additional checks on
hardware. This will be provided as a separate series.
b) during validation checks on CML/ICL, initialization and
playback/capture worked fine, but we observed a reproducible system
freeze while doing load/unload tests, so likely an initialization
missing or a leak to be fixed.

Comments and feedback welcome.
