| * 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>; |
| }; |
