Can you elaborate on > what exactly needs to be moved? The 2 main differences are that SOF does not have any support for this sst_hsw_device_set_config() function - and it should have been abstracted away with a dai operation - and the fixed settings are replaced by topology-defined configurations. we can of course do the SOF support later but you want to make sure the compilation issue is sorted out with the #if !IS_ENABLED() code above.
