+ * DOC: overview
+ *
+ * The DRM mode setting helper functions are common code for drivers to use if
+ * they wish. Drivers are not forced to use this code in their
+ * implementations but it would be useful if the code they do use at least
+ * provides a consistent interface and operation to userspace. Therefore it is
+ * highly recommended to use the provided helpers as much as possible.
+ *
+ * Because there is only one pointer per modeset object to hold a vfunc table
+ * for helper libraries they are by necessity shared among the different
+ * helpers.
+ *
+ * To make this clear all the helper vtables are pulled together in this location here.
