It is quite common for COMEDI subdevices that support commands to support setting `scan_begin_src` to `TRIG_FOLLOW`. This means the next scan begins once all conversions in the current scan are complete. Support the following timing combinations for the AI subdevice: scan_begin_src == TRIG_TIMER && convert_src == TRIG_TIMER scan_begin_src == TRIG_TIMER && convert_src == TRIG_NOW scan_begin_src == TRIG_FOLLOW && convert_src == TRIG_TIMER The actual scan period in microseconds is stored in the `scan_period` member of the private data structure `struct waveform_private`. An `unsigned int` is still wide enough, because the conversion period is no more than `UINT_MAX / 1000` microseconds and the number of conversions is no more than 16 (`N_CHANS * 2`).
