graph connection to node is not bidirectional kernel-5.6.0-rc6

[Vinay Simha B N <simhavcs@xxxxxxxxx>]

hi,

I am getting the endpoint' is not bidirectional(d2l_in, dsi0_out)
warning in compilation, built boot image works on qcom apq8016-ifc6309
board with the dsi->bridge->lvds panel.
Because of this warning i cannot create a .yaml documentation examples.
Please suggest.

tc_bridge: bridge@f {
status = "okay";
    ports {
    #address-cells = <1>;
    #size-cells = <0>;

    port@0 {
        reg = <0>;
        d2l_in: endpoint {
            remote-endpoint = <&dsi0_out>;
        };
    };
};

dsi@1a98000 {
    status = "okay";
...
    ports {
        port@1 {
            dsi0_out:endpoint {
                remote-endpoint = <&d2l_in>;
                data-lanes = <0 1 2 3>;
            };
        };
    };
};
