[PATCH 0/4] Add WoM feature as an IIO event

[inv.git-commit@tdk.com]

From: Jean-Baptiste Maneyrol <jean-baptiste.maneyrol@tdk.com>

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.


Jean-Baptiste Maneyrol (4):
  iio: imu: inv_mpu6050: add WoM (Wake-on-Motion) sensor
  iio: imu: inv_mpu6050: add WoM event inside accel channels
  iio: imu: inv_mpu6050: add new interrupt handler for WoM events
  iio: imu: inv_mpu6050: add WoM suspend wakeup with low-power mode
