The first one is ENP to enable DSVP, and second one is ENM to enable DSVN. Number of GPIO in the array list could be 1 or 2. If only one gpio is specified, only one gpio used to control ENP/ENM. Else if both are specified, DSVP/DSVN could be controlled individually. If this property not specified, treat both as always-on regulators. Property is deprecated.
