MPL refers to Motion Processing Library.
Your device might be using mpu* series chipset from InvenSense (eg mpu3050).
This is a framework that collects data from gyro, accel, compass and 
perform many calculations on the raw data captured by sensors.
You dont have worry about it if you are only using sensors at application 
level.
