Hi For a system with multiple cameras (think of a phone or a tablet), userspace needs to know if the camera is facing the user or the world. AFAIK, we have no way to tell userspace about this it has to rely to tricks/hardcoding. Eg for UVC cameras they match the vid/pid or the camera name. Assuming we define a new field in the acpi table/device tree to describe this.... Would it be an option to add a new V4L2 standard control for this? Any thoughts?
