This is to be used by drivers to signal detection of motion. We also add some possible values for motion as IIO events modifiers: * running * jogging * walking * still These values are supported by Frescale's MMA9553 sensor: http://freescale.com/files/sensors/doc/ref_manual/MMA9553LSWRM.pdf Signed-off-by: Daniel Baluta <daniel.baluta@xxxxxxxxx> Signed-off-by: Irina Tirdea <irina.tirdea@xxxxxxxxx> --- Documentation/ABI/testing/sysfs-bus-iio | 7 +++++++ drivers/iio/industrialio-core.c | 4 ++++ drivers/iio/industrialio-event.c | 1 + include/linux/iio/types.h | 7 ++++++- 4 files changed, 18 insertions(+), 1 deletion(-) diff --git a/Documentation/ABI/testing/sysfs-bus-iio b/Documentation/ABI/testing/sysfs-bus-iio index d760b02..070346d 100644 --- a/Documentation/ABI/testing/sysfs-bus-iio +++ b/Documentation/ABI/testing/sysfs-bus-iio @@ -808,6 +808,13 @@ Description: number or direction is not specified, applies to all channels of this type. +What: /sys/.../events/in_activity_motion_either_en +KernelVersion: 3.17 +Contact: linux-iio@xxxxxxxxxxxxxxx +Description: + Enables or disables motion detection.
