Add several interrupt based sensor detection events: - single tap - double tap - free fall - activity - inactivity - sample frequency - frequency g range approach - documentation All the needed parameters for each and methods of adjusting them, and forward a resulting IIO event for each to the IIO channel. Q: Please have a look into event handling, I'm not sure there seems to be something open (if more simultaneous events arrive)? Q: Please, let me know if the single ABI change is legitimate, where I need to document it? Q: Please, also have a focus on the scale factor handling, is it correctly setup? (I think) I can see it appearing in iio_info. Signed-off-by: Lothar Rubusch <l.rubusch@xxxxxxxxx> --- v1 -> v2: - implementation of all events (but tap2 suppress bit) by means IIO ABI - add sample frequency / ODR configuration - add g ranges configuration - add activity/inactivity using auto-sleep and powersave - add dynamic adjustment of default values for activity/inactivity thresholds and time for inactivity based on ODR and g range (can be overwritten) - add sensor documentation Lothar Rubusch (14): iio: accel: adxl345: reorganize measurement enable iio: accel: adxl345: add debug register access iio: accel: adxl345: reorganize irq handler iio: accel: adxl345: refac set_interrupts and IRQ map iio: accel: adxl345: add single tap feature iio: accel: adxl345: add double tap feature iio: accel: adxl345: add double tap suppress bit iio: accel: adxl345: add freefall feature iio: accel: adxl345: extend sample frequency adjustments iio: accel: adxl345: add g-range configuration iio: accel: adxl345: add activity event feature iio: accel: adxl345: add inactivity feature iio: accel: adxl345: add coupling detection for activity/inactivity docs: iio: add documentation for adxl345 driver Documentation/iio/adxl345.rst | 401 +++++++++ drivers/iio/accel/adxl345.h | 3 +- drivers/iio/accel/adxl345_core.c | 1378 ++++++++++++++++++++++++++++-- 3 files changed, 1703 insertions(+), 79 deletions(-) create mode 100644 Documentation/iio/adxl345.rst -- 2.39.5
