"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".

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

2.8V for this one.
