"csi-afvdd-dovdd"

This regulator provides power for the camera module's Auto Focus, if
available,
and Digital i/O parts of the sensor module. Hence the names of the
rails.

This should probably be "vcc-hdmi-dsi".

oh yes...

On the MIPI-LCD page of the schematics, it says this is connected to
VDD18, so it should be 1.8V.

Rename it to "vcc-dsi-1v8"?

The name is OK. I'm just worried about the voltage. We don't want
users frying their display panel. They probably cost more than the
board itself.

For most of these SBCs, they are designed to work with the panels
they provide. Could you reach out to TL Lim and ask about the voltage
used? Or maybe dig it out of the FEX files?

Thanks

2.8V for this one.
