I wonder if the "omapdss," prefix could be added to *all* remote
endpoints seen by omapdss. Pseudocode:

for each port in dss {
    for each endpoint in port {
        panel = get_phandle(endpoint, "remote-endpoint");

        /* only add prefix if it's not already there (kexec) */
        if (panel.compatible != "omapdss,.*")
            panel.compatible = "omapdss," + panel.compatible;
    }
}
