+* 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>;
+};
