+* 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:
+ - interrupt-parent: Interrupt controller to use
+
+ - 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>;
+};
