-Remove devm_drm_put_bridge()
-----------------------------
+Remove panel_bridge API functions
+---------------------------------
 
-Due to how the panel bridge handles the drm_bridge object lifetime, special
-care must be taken to dispose of the drm_bridge object when the
-panel_bridge is removed. This is currently managed using
-devm_drm_put_bridge(), but that is an unsafe, temporary workaround. To fix
-that, the DRM panel lifetime needs to be reworked. After the rework is
-done, remove devm_drm_put_bridge() and the TODO in
-drm_panel_bridge_remove().
+Now that a drm_bridge is embedded into every drm_panel, the panel_bridge is
+not needed anymore. Its APIs are just accessing the embedded drm_bridge
+transparently, and the are deprecated.
 
-Contact: Maxime Ripard <mripard@kernel.org>,
-         Luca Ceresoli <luca.ceresoli@bootlin.com>
+The funcions to remove are:
+ - drm_panel_bridge_add_typed()
+ - devm_drm_of_get_bridge()
+ - drmm_of_get_bridge()
+ - drm_panel_bridge_remove()
+ - drmm_drm_panel_bridge_release()
+ - devm_drm_panel_bridge_release()
+ - their direct or indirect callers
 
-Level: Intermediate
+Convert users of those functions and eventually remove them when unused, or
+make them static drm_panel.c functions when used internally by the
+``drm_panel.c`` code.
