Hi,
The Linux SOF implementation is historically monolithic in a sense that all features accessible in the firmware can be used via the snd_sof_dev struct in one way or another.
Support for features can not be added or removed runtime and with the current way of things it is hard if not impossible to implement support for dynamic feature support when based on the firmware manifest we can easily enable/access independent modules with the SOF.
In order to be able to support such modularity this series introduces a small framework within SOF for client support using the Auxiliary bus.
Client drivers can be removed runtime and later re-loaded if needed without affecting the core's behaviour, but it is the core's and the platform's duty to create the Auxiliary devices usable in the platform and via the firmware.
There is still a need for SOF manifest update to convey information about features to really make the full dynamic client device creation.
The series will introduce the core SOF client support and converts the generic ipc flood test, ipc message injector and the probes (Intel HDA only) to a client driver.
