Thanks for the review.

In arm,embedded-trace-extension.yaml, the node name pattern is 
"^ete([0-9a-f]+)$".

examples:

# An ETE node without legacy CoreSight connections
   - |
     ete0 {
       compatible = "arm,embedded-trace-extension";
       cpu = <&cpu_0>;
     };
# An ETE node with legacy CoreSight connections
   - |
    ete1 {
       compatible = "arm,embedded-trace-extension";
       cpu = <&cpu_1>;

       out-ports {        /* legacy coresight connection */
          port {
              ete1_out_port: endpoint {
                 remote-endpoint = <&funnel_in_port0>;
              };
          };
       };
    };
