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. + +http://www.ti.com/product/opt3001 + +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>; +};
