Where does this regulator lie physically? Is its presence dependent
on the connection of the sensor, is it part of the EVK carrier board,
or perhaps something else?

Vladimir requested you to move the 'description' (meaning the node
describing the hardware, not a comment explaining the function of the
DT hunk in natural language) to monaco.dtsi too
