This enables adxl372 to capture only over threshold accelerations. 1. Create sysfs files for falling_period and rising_period in events/ dir. 2. Create sysfs files for thresh_falling_value and thresh_rising_value for each axis. 3. Set INT1 reg for acitivity/inactivity and push event code in events fifo on irq. 4. Add additional ABIs in order to explain the user that setting values in the events/ sysfs files also changes device behaviour. 5. Update sysfs docs: renames, added two new entries for the activity_detect_event/ inactivity_detect_event Alexandru Tachici (5): iio: accel: adxl372: add sysfs for time registers iio: accel: adxl372: Add sysfs for g thresholds iio: accel: adxl372: add iio events iio: accel: adxl372: add additional events ABIs iio: accel: adxl372: Update sysfs docs Stefan Popa (1): iio: accel: adxl372: Add support for FIFO peak mode 1. Device FIFO can now be set in peak mode and only over the threshold accelerations will be stored. Changelog V1 -> V2: - switched from custom sysfs for setting the accel thres/timings to standard events interface. - renamed fifo_peak_mode_enable to buffer_peak_mode_enable - on activity/inactivity, event codes are now pushed in the events FIFO - added additional custom sysfs for explaining that setting values in the events/ sysfs files will change the device's behaviour. .../ABI/testing/sysfs-bus-iio-accel-adxl372 | 30 ++ drivers/iio/accel/adxl372.c | 265 +++++++++++++++++- 2 files changed, 293 insertions(+), 2 deletions(-) create mode 100644 Documentation/ABI/testing/sysfs-bus-iio-accel-adxl372 -- 2.20.1
