Which pin in the schematic [1] (page 24) does it refer to? It's not
obvious how to match it up.
The schematic looks the same as the Rock 5B schematic [2] (page 31)
and the Rock 5B dts uses the default pinctrl [3]

Note: The vendor kernel DTS doesn't modify the pinctrl either. [4]

If you try using the default pinctrl (not overriding), does HDMI not work?
