I think this can be a good candidate for the media controller API. It depends on how complex the co-processor is and what kind of processing it performs. I suppose there's no public datasheet. You will probably need to enhance subdev registration, as I'm not aware of any existing use case such as yours where a chain of subdevs unknown to the host controller is connected to the host controller input. > Any pointers on the same and reference links to some documentation > will be highly appreciated. -- Regards, Laurent Pinchart -- To unsubscribe from this list: send the line "unsubscribe linux-media" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
