+* 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>;
+                };
+
+                /* ... */
+        };
