+Object-like macro documentation
+-------------------------------
+
+Object-like macros are distinct from function-like macros. They are
+differentiated by whether the macro name is immediately followed by a
+left parenthesis ('(') for function-like macros or not followed by one
+for object-like macros.
+
+Function-like macros are handled like functions by ``scripts/kernel-doc``.
+They may have a parameter list. Object-like macros have do not have a
+parameter list.
+
+The general format of an object-like macro kernel-doc comment is::
+
+ /**
+ * define object_name - Brief description.
+ *
+ * Description of the object.
+ */
+
+Example::
+
+ /**
+ * define MAX_ERRNO - maximum errno value that is supported
+ *
+ * Kernel pointers have redundant information, so we can use a
+ * scheme where we can return either an error code or a normal
+ * pointer with the same return value.
+ */
+ #define MAX_ERRNO 4095
+
+Example::
+
+ /**
+ * define DRM_GEM_VRAM_PLANE_HELPER_FUNCS - \
+ * Initializes struct drm_plane_helper_funcs for VRAM handling
+ *
+ * This macro initializes struct drm_plane_helper_funcs to use the
+ * respective helper functions.
+ */
