I've quickly resurrected my FPDLink branch, ported to 6.12, and pushed it to https://github.com/6by9/linux/tree/rpi-6.12.y-fpdlink
libcamera does detect the cameras, but in the same way you're seeing, I getfrom libcamera, andfrom the kernel logs
My media controller tree isSame as you, we have pads that still have their default format (640x480 UYVY8_1X16 for me).
Time to put in a load of logging for what formats are and aren't getting configured.
It looks like the FPDlink and GMSL drivers reject setting the format on the source pad, and will just return the current format. video-mux will accept it under some situations. So I wonder if the format is getting messed up there.
