-* Devantech SRF04 ultrasonic range finder
-  Bit-banging driver using two GPIOs
-
-Required properties:
- - compatible:	Should be "devantech,srf04"
-
- - trig-gpios:	Definition of the GPIO for the triggering (output)
-		This GPIO is set for about 10 us by the driver to tell the
-		device it should initiate the measurement cycle.
-
- - echo-gpios:	Definition of the GPIO for the echo (input)
-		This GPIO is set by the device as soon as an ultrasonic
-		burst is sent out and reset when the first echo is
-		received.
-		Thus this GPIO is set while the ultrasonic waves are doing
-		one round trip.
-		It needs to be an GPIO which is able to deliver an
-		interrupt because the time between two interrupts is
-		measured in the driver.
-		See Documentation/devicetree/bindings/gpio/gpio.txt for
-		information on how to specify a consumer gpio.
-
-Example:
-srf04@0 {
-	compatible = "devantech,srf04";
-	trig-gpios = <&gpio1 15 GPIO_ACTIVE_HIGH>;
-	echo-gpios = <&gpio2  6 GPIO_ACTIVE_HIGH>;
-};
