+* MAX44009 Ambient Light Sensor
+
+Required properties:
+
+- compatible: should be "maxim,max44009"
+- reg: the I2C address of the device (default is <0x4a>)
+
+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:
+
+max44009: light-sensor@4a {
+ compatible = "maxim,max44009";
+ reg = <0x4a>;
+
+ interrupt-parent = <&gpio1>;
+ interrupts = <17 IRQ_TYPE_EDGE_FALLING>;
+};
