2015-03-09iio: Move iio userspace applications out of stagingRoberta Dobrescu5-1556/+0
This patch moves iio userspace applications out of staging, to tools/iio/ and adds a Makefile in order to compile them easily. It also adds tools/iio/ to MAINTAINERS file. Signed-off-by: Roberta Dobrescu <roberta.dobrescu@gmail.com> Signed-off-by: Jonathan Cameron <jic23@kernel.org>
2015-03-09staging: iio: Documentation: Introduce iio_utils.cRoberta Dobrescu4-638/+679
This patch removes inline functions from iio_utils.h in order to clean the code. iio_utils.c contains the implementation of the functions used by iio_event_monitor.c, lsiio.c or generic_buffer.c and iio_utils.h contains the declarations of these functions. Since iio_utils.h is modified, generic_buffer.c and iio_event_monitor.c must include stdlib.h.

2015-03-09staging: iio: Documentation: iio_event_monitor: Include linux/iio/types.hRoberta Dobrescu1-0/+1

2015-01-27iio: core: Remove IIO_EV_TYPE_INSTANCEIrina Tirdea1-2/+0
By introducing IIO_EV_TYPE_CHANGE, IIO_EV_TYPE_INSTANCE becomes redundant. The effect of IIO_EV_TYPE_INSTANCE can be obtained by using IIO_EV_TYPE_CHANGE with IIO_EV_INFO_VALUE set to 1. Remove all instances of IIO_EV_TYPE_INSTANCE and replace them with IIO_EV_TYPE_CHANGE where needed.

2015-01-27iio: core: Introduce CHANGE event typeIrina Tirdea1-0/+2
A step detector will generate an interrupt each time N step are detected. A device that has such pedometer functionality is Freescale's MMA9553L: http://www.freescale.com/files/sensors/doc/ref_manual/MMA9553LSWRM.pdf. Introduce IIO_EV_TYPE_CHANGE event type for events that are generated when the channel passes a threshold on the absolute change in value.

2014-12-12iio: buffer: Drop get_length callbackLars-Peter Clausen1-2/+2
We already do have the length field in the struct iio_buffer which is expected to be in sync with the current size of the buffer. And currently all implementations of the get_length callback either return this field or a constant number. This patch removes the get_length callback and replaces all occurrences in the IIO core with directly accessing the length field of the buffer.

2014-12-12iio: Remove get_bytes_per_datum() from iio_buffer_access_funcsLars-Peter Clausen1-2/+2
There haven't been any users of the get_bytes_per_datum() callback for a while. The core assumes that the number of bytes per datum can be calculated based on the enabled channels and the storage size of the channel and iio_compute_scan_bytes() is used to compute this number. So remove the callback. Signed-off-by: Lars-Peter Clausen <lars@metafoo.de> Signed-off-by: Jonathan Cameron <jic23@kernel.org>

2014-01-01iio: Fix a buffer overflow in iio_utils.h example codeCraig Markwardt1-3/+3
This was originally reported by Craig Markwardt on Zubair Lutfullah's blog and Zubair forwarded it to linux-iio@vger.kernel.org. No email address known. The code first counted the number of enabled channels, then created an array to hold information about them. The code that filled this array then stored whether a given element was enabled inside the array. Curriously this element was never used. Craig's patch added a local temporary variable to avoid the buffer overrun. Jonathan then removed the original enabled element of the structure as it was not needed at all.
