+* AP3216C Ambient Light and Proximity Sensor
+
+Required properties:
+  - compatible: should be "liteon,ap3216c"
+  - reg: the I2C address of the sensor (default is <0x1e>)
+
+Optional properties:
+  - interrupts: interrupt mapping for GPIO IRQ. Should be configured with
+    IRQ_TYPE_EDGE_FALLING.
+
+Refer to interrupt-controller/interrupts.txt for generic interrupt client
+node bindings.
+
+Example:
+
+light-sensor@1e {
+	compatible = "liteon,ap3216c";
+	reg = <0x1e>;
+
+	interrupt-parent = <&gpio1>;
+	interrupts = <17 IRQ_TYPE_EDGE_FALLING>;
+};
