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: Andreas Klinger <ak@xxxxxxxxxxxxx> --- .../ABI/testing/sysfs-bus-iio-distance-srf08 | 22 ++++++++++++++++++++++ 1 file changed, 22 insertions(+) create mode 100644 Documentation/ABI/testing/sysfs-bus-iio-distance-srf08 diff --git a/Documentation/ABI/testing/sysfs-bus-iio-distance-srf08 b/Documentation/ABI/testing/sysfs-bus-iio-distance-srf08 new file mode 100644 index 000000000000..0a1ca1487fa9 --- /dev/null +++ b/Documentation/ABI/testing/sysfs-bus-iio-distance-srf08 @@ -0,0 +1,22 @@ +What /sys/bus/iio/devices/iio:deviceX/sensor_sensitivity +Date: January 2017 +KernelVersion: 4.11 +Contact: linux-iio@xxxxxxxxxxxxxxx +Description: + Show or set the gain boost of the amp, from 0-31 range. + default 31 + +What /sys/bus/iio/devices/iio:deviceX/sensor_max_range +Date: January 2017 +KernelVersion: 4.11 +Contact: linux-iio@xxxxxxxxxxxxxxx +Description: + Show or set the maximum range between the sensor and the + first object echoed in meters.
