From: Jean-Baptiste Maneyrol <jean-baptiste.maneyrol@xxxxxxx> Add WoM (Wake-on-Motion) feature for all chips supporting it (all except MPU-6000/6050/9150). WoM compares the magnitude of the current accel sample with the previous one against a threshold and returns an interrupt event if the value is higher. Report WoM as an accel mag_adaptive_rising IIO event, add system wakeup functionality if WoM is on and put the chip in low-power mode when the system is suspended. WoM threshold value is in SI units since the chip is using an absolute value in mg.
