The parallel-display driver used an undocumented, non-standard property "fsl,panel" to optionally associate with a drm_panel device. This patch fixes the driver to use the same OF graph bindings as the LDB driver instead:

parallel-display {
        compatible = "fsl,imx-parallel-display";
        ...

        port@1 {
                reg = <1>;

                parallel_out: endpoint {
                        remote_endpoint = <&panel_in>;
                };
        };
};

panel {
        ...

        port {
                panel_in: endpoint {
                        remote-endpoint = <&parallel_out>;
                };
        };
};
