+* TAOS TSL 2580/2581/2583 ALS sensor
+
+Required properties:
+
+  - compatible: Should be one of
+		"amstaos,tsl2580"
+		"amstaos,tsl2581"
+		"amstaos,tsl2583"
+  - reg: the I2C address of the device
+
+Optional properties:
+
+  - interrupt-parent: should be the phandle for the interrupt controller
+  - interrupts: the sole interrupt generated by the device
+
+  Refer to interrupt-controller/interrupts.txt for generic interrupt client
+  node bindings.
+
+  - vcc-supply: phandle to the regulator that provides power to the sensor.
+
+Example:
+
+tsl2581@29 {
+	compatible = "amstaos,tsl2581";
+	reg = <0x29>;
+};
