* Texas Instruments OPT3001 Ambient Light Sensor
2
3
The driver supports interrupt-driven and interrupt-less operation, depending
4
on whether an interrupt property has been populated into the DT. Note that
5
the optional generation of IIO events on rising/falling light threshold changes
6
requires the use of interrupts. Without interrupts, only the simple reading
7
of the current light value is supported through the IIO API.
