+* MaxBotix I2CXL-MaxSonar ultrasonic distance sensor of type mb12x2 using
+  the i2c interface for ranging
+
+Required properties:
+ - compatible:		Should be "maxbotix,i2cxl"
+
+ - reg:			i2c address of the device
+
+Optional properties:
+ - status-gpios:	Status gpio (input) 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 until data can be
+			retrieved.
+
+Example:
+proximity@70 {
+	compatible = "maxbotix,i2cxl";
+	reg = <0x70>;
+	status-gpios = <&gpio2 2 GPIO_ACTIVE_HIGH>;
+};
