Could you elaborate on what you mean by dual display panels ? From what
I understand of the patch series, this seems to be what I have called
dual port panels, that is panels that have two input ports to double the
bandwidth, but still operate as one display.

Indeed, looks like that. I don't have the datasheets so I am trying to
get some pieces of information. Judging by the usage of these panels -
Qualcomm DSI with qcom,dual-dsi-mode - it indeed is one panel with two
links.

I would need to rephrase it.

Best regards,
Krzysztof

Thanks :-)

Documentation/devicetree/bindings/display/bridge/thine,thc63lvd1024.yaml
may be of interest to you, it's a bridge with two LVDS inputs. On the
other side, I've used
Documentation/devicetree/bindings/display/bridge/renesas,lvds.yaml which
is an LVDS encoder with a single output, but with the ability to operate
in dual link mode by coupling two encoder instances.
