In general, a device may have more than one interrupt output. Hence in
general, the interrupts property is a list of 1 or more interrupt
specifiers. In this case, that list should be a single entry. The
binding should state this. how about:

----------
Optional properties:
interrupts: Contains a single interrupt specifier which describes the
LM90 XXXX output. See interrupt-controller/interrupts.txt for the format.
----------

(where you'd replace XXXX with the pin/signal name from the datasheet).
