Indeed according to moortec,mr75203.yaml "intel,vm-map" is listed as 
required
but the code indicates otherwise:

/*
  * Incase intel,vm-map property is not defined, we assume
  * incremental channel numbers.
  */

The probe function takes care in case it is missing and does not fail.
It also seems less reasonable that an Intel proprietary parameter will be
required and not optional.
So in patch 03 I fixed the moortec,mr75203.yaml documentation and 
changed it to
be optional.
