-* Devantech SRF04 ultrasonic range finder
- Bit-banging driver using two GPIOs
- - 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
- 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.
- compatible = "devantech,srf04";
- trig-gpios = <&gpio1 15 GPIO_ACTIVE_HIGH>;
- echo-gpios = <&gpio2 6 GPIO_ACTIVE_HIGH>;
