I guess that would mean also including connector node (hdmi_con_in) in DTSI, since it is referenced inside. However, not all boards have HDMI connector, so I didn't include it in DTSI.
You're absolutely right on this. I wish there was someway to get rid of this duplication but that's a whole different problem to discuss.
Great work by the way!
