+* Texas Instruments OPT3001 Ambient Light Sensor
+
+http://www.ti.com/product/opt3001
+
+Required properties:
+  - compatible: should be "ti,opt3001"
+  - reg: the I2C address of the sensor
+  - 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>;
+};
