19 The function comedi_get_timer converts the frequency frequency to a
20 number suitable to send to the driver in a comedi_trig structure. This
21 function remains for compatibility with very old versions of Comedi,
22 that converted sampling rates to timer values in the library. This
23 conversion is now done in the kernel, and every device has the timer
24 type nanosec_timer, indicating that timer values are simply a time
25 specified in nanoseconds.
