In general there should be sandbox tests written for adding any such new UCLASS.
Tero,
This is not a generic UCLASS driver. This is a K3 specific driver. So should this be really introducing a new UCLASS?
Well, AVS is kind of generic across TI SoCs. However, I am fine just using UCLASS_MISC if we don't want to introduce a new uclass.... assuming we don't get sequencing issues with remoteproc if we do that.
