+* MaxBotix I2CXL-MaxSonar ultrasonic distance sensor of type  mb1202,
+  mb1212, mb1222, mb1232, mb1242, mb7040 or mb7137 using the i2c interface
+  for ranging
+
+Required properties:
+ - compatible:         "maxbotix,mb1202",
+                       "maxbotix,mb1212",
+                       "maxbotix,mb1222",
+                       "maxbotix,mb1232",
+                       "maxbotix,mb1242",
+                       "maxbotix,mb7040" or
+                       "maxbotix,mb7137"
+
+ - reg:                        i2c address of the device, see also i2c/i2c.txt
+
+Optional properties:
+ - interrupts:         Interrupt used to announce the preceding reading
+                       request has finished and that data is available.
+                       If no interrupt is specified the device driver
+                       falls back to wait a fixed amount of time until
+                       data can be retrieved.
+
+Example:
+proximity@70 {
+       compatible = "maxbotix,mb1232";
+       reg = <0x70>;
+       interrupt-parent = <&gpio2>;
+       interrupts = <2 IRQ_TYPE_EDGE_FALLING>;
+};
