-* Capella CM36651 I2C Proximity and Color Light sensor
-
-Required properties:
-- compatible: must be "capella,cm36651"
-- reg: the I2C address of the device
-- interrupts: interrupt-specifier for the sole interrupt
-	      generated by the device
-- vled-supply: regulator for the IR LED. IR_LED is a part
-	      of the cm36651 for proximity detection.
-	      As covered in ../../regulator/regulator.txt
-
-Example:
-
-	i2c_cm36651: i2c-gpio {
-		/* ... */
-
-		cm36651@18 {
-			compatible = "capella,cm36651";
-			reg = <0x18>;
-			interrupt-parent = <&gpx0>;
-			interrupts = <2 0>;
-			vled-supply = <&ps_als_reg>;
-		};
-
-		/* ... */
