Enable HDMI output on i.MX8MP DHCOM PDK2 and PDK3. The I2C5 on PDK2 and

of HDMI DDC mode to permit connection of other I2C devices on those buses.
Are you able to read the HDMI EDID with such configuration? I have the
patch ready for verdin imx8mp, I just did not have time to figure out
this last details.
Yes with ddc-i2c-bus in hdmi_tx{} node, no with ddc-i2c-bus in connector node. Maybe that's what you're running into ? The DW HDMI core needs the ddc-i2c-bus property in hdmi_tx{} node if you use non-native I2C bus for the DDC channel.
What benefit does the hdmi-connector provide over just omitting it?
Just for documentation purposes?
I was under the impression describing the hardware in DT in full was the
best practice (TM), hence it is in full here.
