How to enable the internal camera on SP514-51N in GNU/Linux?

Webcam is not working in GNU/Linux (latest POP OS!, properly updated) - anybody made it working? "Not working" means no camera present in the OS.

I am afraid it is not even listed in lsusb:/

In Windows (I've got dualboot), it works normally.

Here is some debug info:

    Here is the spec I have on the camera:

    Search on the Chicony model number to see if they have Linux drivers for it. It uses a MIPI interface off the PCH:

    So, pretty much standard…

    I've tried to google it, and no luck, there is nothing:

    Here is the info from MS Windows device list:

    So you might have to wait for the Linux devs to get it ported. It often takes a year or so for new models to be fully supported…

    One thing, though, if it's "Chicony" according to @billsey , why is it listed as "Intel" in MS Windows device list?

    Chicony designs and builds it, using Intel chips.
