The classes E31x_db and Neon were importing the AD936xDboard mixin class after their parent class, not before. This means the mixin couldn't be used to override classes from the parent class, because Python's MRO will go to the first class in the inheritance list. Because there is no use of super() in these classes, the reordering has no other effect than prioritize AD936xDboard over DboardManagerBase when it comes to resolving parent methods.
