+* Devantech SRF04 ultrasonic range finder
+ Bit-banging driver
+
+Required properties:
+ - compatible: Should be "devantech,srf04"
+ - trig-gpios: Definition of the GPIO for the triggering input
+ - echo-gpios: Definition of the GPIO for the echo
+ needs to be an interrupt input
+ See Documentation/devicetree/bindings/gpio/gpio.txt
+
+Example:
+srf04@0 {
+ compatible = "devantech,srf04";
+ trig-gpios = <&gpio1 15 GPIO_ACTIVE_HIGH>;
+ echo-gpios = <&gpio2 6 GPIO_ACTIVE_HIGH>;
