This channel will be used for exposing information about activity composite sensors. Activities supported so far: * running * jogging * walking * still THRESHOLD event is used to signal a change in the activity state. We associate a confidence interval for each activity expressed as a percentage from 0 to 100. * 0, means the sensor IS NOT reporting that activity. * 100, means the sensor IS reporting that activity. Users of this interface have two possible means to gather information about the ongoing activities. 1. Event based, via event file descriptor * sensor may report an event when ENTERING an activity or LEAVING an activity based on a threshold value. * drivers will wake up applications waiting data on the event fd 2. Polling, by reading the sysfs associated attribute files: * /sys/bus/iio/devices/iio:device0/in_activity_running_input expressed as percentage confidence value from 0 to 100. This will offer an interface for Android significant motion composite sensor defined here: http://source.android.com/devices/sensors/composite_sensors.html Activities listed above are supported by Freescale's MMA9553 sensor: http://freescale.com/files/sensors/doc/ref_manual/MMA9553LSWRM.pdf Signed-off-by: Irina Tirdea <irina.tirdea@intel.com> Signed-off-by: Daniel Baluta <daniel.baluta@intel.com> Signed-off-by: Jonathan Cameron <jic23@kernel.org> |
