How do you envisage the direct CSI-to-ISP streaming shall be supported? - How shall the final media graph(s) look like? - How many media devices are registered and which driver registers it or them? - How can the user decide whether direct (csi2isp) or indirect (mem2mem) streaming shall be used? While it is certainly OK to introduce this support only at a later stage, it makes sense to consider this right from the start to avoid some nasty changes e.g. in how this hardware is exposed to user space. Also, we are facing a similiar challenge with recent Rockchip ISP hardware (RK3588, RK3576, ...) and it would be great to hear your thoughts about that.
