| * 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>; | |
| }; |
