+*HTU21 - Measurement-Specialties htu21 temperature & humidity sensor and humidity part of MS8607 sensor
+
+Required properties:
+
+       - compatible: should be "meas,htu21" or "meas,ms8607-humidity"
+       - reg: I2C address of the sensor
+
+Example:
+
+htu21@40 {
+       compatible = "meas,htu21";
+       reg = <0x40>;
+};
