* Texas Instruments OPT3001 Ambient Light Sensor

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.

Required properties:

  - compatible: should be "ti,opt3001"

  - reg: the I2C address of the sensor

Optional properties:

  - interrupts: interrupt mapping for GPIO IRQ (configure for falling edge)

Example:

opt3001@44 {

	compatible = "ti,opt3001";

	reg = <0x44>;

	interrupt-parent = <&gpio1>;

	interrupts = <28 IRQ_TYPE_EDGE_FALLING>;
