iio: distance: srf08: add driver ABI documentation (1dc2af87) · Commits · 戴 / test

Add sysfs-bus-iio-distance-srf08 for individual attributes of the driver, especially: - sensitivity which the device documentation calls gain for amplifying the signal - max_range for limiting the maximum distance for expected echos and therefore limiting the time waiting for telegrams Signed-off-by:

		What /sys/bus/iio/devices/iio:deviceX/sensor_max_range
		Date: January 2017
		KernelVersion: 4.11
		Contact: linux-iio@vger.kernel.org
		Description:
		Show or set the maximum range between the sensor and the
		first object echoed in meters. Default value is 6.020.
		This setting limits the time the driver is waiting for a
		echo.
		Showing the range of available values is represented as the
		minimum value, the step and the maximum value, all enclosed
		in square brackets.
		Example:
		[0.043 0.043 11.008]
