I've taken a shot today trying to convert over to the audio-graph-card
method (which isn't yet upstream, but in -next), but I've been running
into some quirks.

Part of the issue is the adv7533 bridge already has a endpoint port
entry for the dsi output. So when I add the codec_endpoint port, it
wants the two port entries to be enumerated, so I get something like:

port@0 {
    adv7533_in: endpoint {
        remote-endpoint = <&dsi_out0>;
    };
};
port@1 {
    codec_endpoint: endpoint {
        remote-endpoint = <&i2s0_cpu_endpoint>;
    };
};

But this causes it to try to link to hdmi-hifi.1 (which doesn't exist)
instead of hdmi-hifi.0.

If I instead swap the entries, so the codec_endpoint is first on port
0, then the the audio link is properly setup, but the dsi
initialization falls over.

Any suggestions here?

thanks
