I recently came across the new DTS Addon proposal:
https://lore.kernel.org/devicetree-compiler/20260112142009.1006236-1-herve.codina@xxxxxxxxxxx/
https://lore.kernel.org/devicetree-compiler/20260409115426.352214-1-herve.codina@xxxxxxxxxxx/

which might be handy to unify overlays for all 15 and 22-pin Pi-style FFC
connectors, which I guess are now quite popular across different vendor
boards.

Ack. I'll add https://docs.beagle.cc/boards/beagley/ai/03-design.html#csi
in v2 unless there's a better link I can use (?)

Thanks,
