* 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:
|
|
- interrupt-parent: should be the phandle for the interrupt controller
|
|
- 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>;
|
|
};
