It looks like the comedilib docs haven't been synced with the drivers 
recently.  This quote may help:

To select the bnc trigger input on the 4020 (instead of the dio input),
specify a nonzero channel in the chanspec.  If you wish to use an external
master clock on the 4020, you may do so by setting the scan_begin_src
to TRIG_OTHER, and using an INSN_CONFIG_TIMER_1 configuration insn
to configure the divisor to use for the external clock.
