My bad. that was typo.

This looks very very odd... The whole sii9022 node should be here.
ok. i was also bit confused with this placement.

You add the same label, "dpi_out" to both endpoints. Does this even compile?
As there's just one port, you can leave out the 'ports' node.
Will check. the ports was added as per documentation in video-interfaces.txt
Can you suggest how to add the 2 dpi_out endpoints?
Thanks
