I can now confirm that IPU6 driver upstreaming is now planned, with IPU6 input system driver to be upstreamed first. The intent is that we would have patches for review on LMML around the end of the year. The processing system driver will need more work to replace the custom interface. For a fully functional camera stack, also libcamera support for IPU6 will be needed. I think I can say a major factor for why we're here is that the original intent was to use a different interface for upstream but as we don't have one yet and probably won't for quite some time, this doesn't really seem like a viable option anymore. So I'm afraid I can't promise a quick fix but at the same time I can say work is being done to address this. -- Kind regards, Sakari Ailus
