-* ISL 29018/29023/29035 I2C ALS, Proximity, and Infrared sensor
-
-Required properties:
-
-  - compatible: Should be one of
-		"isil,isl29018"
-		"isil,isl29023"
-		"isil,isl29035"
-  - reg: the I2C address of the device
-
-Optional properties:
-
-  - 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:
-
-isl29018@44 {
-	compatible = "isil,isl29018";
-	reg = <0x44>;
-	interrupt-parent = <&gpio>;
-	interrupts = <TEGRA_GPIO(Z, 2) IRQ_TYPE_LEVEL_HIGH>;
-};
