J17 on i.MX8mp EVK base board is a HDMI type A connector.
It connects with i.MX8mp HDMI PHY.  Add support for it.

Is there a non-nativ HDMI connector? If not this is somewhat misleading.

That's an input port of the HDMI connector. It should be called hdmi_in or similar.
Right now it's connecting 'hdmi_out' and 'hdmi_tx_out' which looks confusing.

Yes, there is a 'hdmi-connector' node in this file.
It is for ADV7535 MIPI DSI to HDMI bridge.

I'll use hdmi_in in next version.  Thanks.
