From: Irina Tirdea <irina.tirdea@xxxxxxxxx> This event is needed for the step detection functionality of a pedometer: an interrupt is generated by the hardware device each time a step is detected. To support this, we add a new iio event. For more information on the pedometer requirements for Android see http://source.android.com/devices/sensors/composite_sensors.html#detector. A device that has the pedometer functionality this interface needs to support is Freescale's MMA9553L: http://www.freescale.com/files/sensors/doc/ref_manual/MMA9553LSWRM.pdf Signed-off-by: Irina Tirdea <irina.tirdea@xxxxxxxxx> Signed-off-by: Daniel Baluta <daniel.baluta@xxxxxxxxx> --- Documentation/ABI/testing/sysfs-bus-iio | 7 +++++++ drivers/iio/industrialio-event.c | 1 + include/linux/iio/types.h | 1 + 3 files changed, 9 insertions(+) diff --git a/Documentation/ABI/testing/sysfs-bus-iio b/Documentation/ABI/testing/sysfs-bus-iio index c02785d..fd66073 100644 --- a/Documentation/ABI/testing/sysfs-bus-iio +++ b/Documentation/ABI/testing/sysfs-bus-iio @@ -815,6 +815,13 @@ Description: Enables or disables motion detection.
