Subject: [PATCH v3 3/3] iio: distance: srf08: add driver ABI documentation
Date: Tue, 17 Jan 2017 14:50:06 +0100 [thread overview]
Message-ID: <20170117135006.GA22903@andreas> (raw)
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
