+* MaxSonar-I2CXL ultrasonic distance sensor of type mb12x2 using the i2c
+  interface for ranging
+
+Required properties:
+ - compatible:		Should be "maxbotix,mb12x2"
+
+ - reg:			i2c address of the device
+
+Optional properties:
+ - status-gpios:	Definition of the status gpio (input) which is used
+			to announce the preceding reading request has
+			finished and that data is available. If no status
+			gpio is specified the device driver falls back to
+			wait a certain amount of time (15 ms) until data
+			can be retrieved.

+Example:
+mb@70 {
+	compatible = "maxbotix,mb12x2";
+	reg = <0x70>;
+	status-gpios = <&gpio2 2 GPIO_ACTIVE_HIGH>;
