* iio: Add modifier for DUV lightMaxime Roussin-Bélanger2018-07-231-0/+2

* iio: Add channel for PhaseMathieu Othacehe2018-07-211-0/+2
| | | | | | | | | | | | 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.

* iio: Add channel for Position RelativeEugen Hristev2018-06-101-0/+2
| | | | | | | | | | | | | | | 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.

* iio: Add channel for GravitySong Hongyan2017-01-051-0/+2
| | | | | | | | | | | | | | Add new channel types support for gravity sensor. Gravity sensor provides an application-level or physical collection that identifies a device that measures exclusively the force of Earth's gravity along any number of axes.

* iio: event_monitor: report unsupported eventsLinus Walleij2015-08-161-1/+5
| | | | | | | | | | This makes the event monitor bail out with a helpful error message if a device does not support events, as a related fix to iio core now makes it return -ENODEV properly.

| | | | | | | | | | | This patch indends to make some cleanup and send printf error messages to stderr. The changes were performed with coccinelle for failure messages and manual for other cases, such as wrong usage messages.

| | | | | | | | | Refactor the code in print_event() to reduce code duplication and better reflect that the type is output unconditionally, as well as cascade the dependency of the diff-channel. Saves a few lines of code, as well. Signed-off-by: Hartmut Knaack <knaack.h@gmx.de> Signed-off-by: Jonathan Cameron <jic23@kernel.org>

| | | | | | | | Move up error handling code to preserve the errno coming from ioctl(), before it may be changed by close(). Signed-off-by: Hartmut Knaack <knaack.h@gmx.de> Signed-off-by: Jonathan Cameron <jic23@kernel.org>
* tools:iio: save errno firstHartmut Knaack2015-05-311-3/+3
| | | | | | | | | | The man-page of errno states, that errno should be saved before doing any library call, as that call may have changed the value of errno. So, when encountering any error, save errno first. This patch affects generic_buffer.c, iio_event_monitor.c and iio_utils.c.

* tools: iio: Define _GNU_SOURCE in MakefileRoberta Dobrescu2015-03-091-2/+0
| | | | | | | | | | | | | | Definition of _GNU_SOURCE is needed to get rid of some warnings, such as: warning: implicit declaration of function `asprintf'. generic_buffer.c and iio_event_monitor.c define _GNU_SOURCE, but it is also needed in lsiio.c and iio_utils.c. For this reason, this patch adds the definition in Makefile and removes it from where it already exists.
