+* CAPELLA CM36651 I2C Proximity sensor with Color sensor
+
+Required properties:
+- compatible: must be "capella,cm36651" or "cm36651"
+- reg: the I2C address of light sensor
+- interrupts: interrupt to which the chip is connected
+- vled-suppled: regulator for the sensor device, refere to
+               Documentation/devicetree/bindings/regulator/regulator.txt
+
+Example:
+
+       i2c_cm36651: i2c-gpio-2 {
+               /* ... */
+
+               cm36651@18 {
