We need the staging fixes in here as well. Signed-off-by: Greg Kroah-Hartman

tools: iio: iio_generic_buffer: make num_loops signed

2019-01-12T18:17:56Z

Currently, num_loops is unsigned, but it's set by strtoll, which returns a (signed) long long int. This could lead to overflow, and it also makes the check "num_loops < 0" always be false, since num_loops is unsigned. Setting num_loops to -1 to loop forever is almost working because num_loops is getting set to a very high number, but it's technically still incorrect. Fix this issue by making num_loops signed. This also fixes an error found by Smatch.

iio: Add modifiers for ethanol and H2 gases

Add ethanol and H2 gas modifiers: * IIO_MOD_ETHANOL * IIO_MOD_H2 Signed-off-by: Andreas Brauchli Acked-by: Matt Ranostay Signed-off-by: Jonathan Cameron

iio: add IIO_MASSCONCENTRATION channel type

2018-12-16T14:05:57Z

Measuring particulate matter in ug / m3 (micro-grams per cubic meter) is de facto standard. Existing air quality sensors usually follow this convention and are capable of returning measurements using this unit. IIO currently does not offer suitable channel type for this type of measurements hence this patch adds this. In addition, extra modifiers are introduced used for distinguishing between fine pm1, pm2p5 and coarse pm4, pm10 particle measurements, i.e IIO_MOD_PM1, IIO_MOD_PM25 and IIO_MOD_PM4, IIO_MOD_PM10. pmX consists of particles with aerodynamic diameter less or equal to X micrometers.

iio: Add channel for Phase

2018-07-21T14:28:14Z

Add new channel type support for phase. This channel may be used by Time-of-flight sensors to express the phase difference between emitted and received signals. Those sensor will then use the phase shift of return signals to approximate the distance to objects. Signed-off-by: Mathieu Othacehe Signed-off-by: Jonathan Cameron

iio: Add channel for Position Relative

2018-06-10T10:55:15Z

Add new channel type for relative position on a pad. These type of analog sensor offers the position of a pen on a touchpad, and is represented as a voltage, which can be converted to a position on X and Y axis on the pad. The channel will hand the relative position on the pad in both directions. The channel can then be consumed by a touchscreen driver or read as-is for a raw indication of the touchpen on a touchpad.

tools: iio: iio_generic_buffer: allow continuous looping

2018-05-20T13:55:58Z

Sometimes it's useful to stream samples forever, such as when stress-testing a driver overnight to check for memory leaks or other issues. When the program receives a signal, it will gracefully cleanup, so it is still safe to terminate at any time. Add support for specifying a negative -c option, meaning that we should loop forever. To do so, we need to use a long long (instead of just long) for num_loops so that current code specifying num_loops greater than UNSIGNED_LONG_MAX doesn't break.
