48  * struct drm_property - modeset object property
50  * This structure represent a modeset object property. It combines both the name
51  * of the property with the set of permissible values. This means that when a
52  * driver wants to use a property with the same name on different objects, but
53  * with different value ranges, then it must create property for each one. An
56  * property structure can be instantiated multiple times for the same object.
58  * symbolic property will have the same modeset object ID on all modeset

104 	 *     the number of enumerated values defined by the property minus one,
