+ * DOC: component helper usage recommendations

+ * independent hardware blocks are recommended to use the :ref:`component helper
+ * library<component>`. For consistency and better options for code reuse the
+ * following guidelines apply:
+ *
+ * - The entire device initialization procedure should be run from the
+ * &component_master_ops.master_bind callback, starting with drm_dev_init(),
+ * then binding all components with component_bind_all() and finishing with
+ * drm_dev_register().
+ *
+ * - The opaque pointer passed to all components through component_bind_all()
+ * should point at &struct drm_device of the device instance, not some driver
+ * specific private structure.
+ *
+ * - The component helper fills the niche where further standardization of
+ * interfaces is not practical. When there already is, or will be, a
+ * standardized interface like &drm_bridge or &drm_panel, providing its own
+ * functions to find such components at driver load time, like
+ * drm_of_find_panel_or_bridge(), then the component helper should not be
+ * used.
