Hello

The A80 have one also, so I need to set minItems: 1
But setting both minItems: 1 and maxItems:1 lead to a check failure:
properties:resets: {'minItems': 1, 'maxItems': 1} is not valid under any of the given schemas

How to do that ?

Furthermore, I try to do that for interrupts and reg, since they are also mandatory and same failure.

Fixed

Thanks
