Jonathan, I am trying to understand howto apply this to cma3000. I
have few parameters like below. Would you be able to suggest how
the sysfs entries should look like for the below parameters or are these
still to be defined.

grange:  2000, 8000 mg 
sampling frequency  : 40, 100, 400 Hz
Modes : Motion detect, Measurement, Free fall

Thanks
Hemanth
