+The driver supports interrupt-driven and interrupt-less operation, depending
+on whether an interrupt property has been populated into the DT. Note that
+the optional generation of IIO events on rising/falling light threshold changes
+requires the use of interrupts. Without interrupts, only the simple reading
+of the current light value is supported through the IIO API.
