57  * This structure represent a modeset object property. It combines both the name
58  * of the property with the set of permissible values. This means that when a
59  * driver wants to use a property with the same name on different objects, but
60  * with different value ranges, then it must create property for each one. An
63  * property structure can be instantiated multiple times for the same object.
