There is no need for a label ("soc_funnel) before the device name if that
device is not referenced elsewhere in the DTS.  The same comment applies to most
of the component listed below.

When more than one port is present it is customary to add another level of
imbrication like it is done for funnels above:
                         "ports {"
                                port at 0 {
                                ...
                                port at 1 {
                                ...
                        }

The same comment applies to both etf.
