+	 * The @edid_read callback is the preferred way of reporting mode
+	 * information for a display connected to the bridge output. Bridges
+	 * that support reading EDID shall implement this callback and leave
+	 * the @get_modes callback unimplemented.
+	 *
+	 * The caller of this operation shall first verify the output
+	 * connection status and refrain from reading EDID from a disconnected
+	 * output.
+	 *
+	 * This callback is optional. Bridges that implement it shall set the
+	 * DRM_BRIDGE_OP_EDID flag in their &drm_bridge->ops.
+	 *
+	 * The connector parameter shall be used for the sole purpose of EDID
+	 * retrieval, and shall not be stored internally by bridge drivers for
+	 * future usage.
+	 *
+	 * RETURNS:
+	 *
+	 * An edid structure newly allocated with drm_edid_alloc() or returned
+	 * from drm_edid_read() family of functions on success, or NULL
+	 * otherwise. The caller is responsible for freeing the returned edid
+	 * structure with drm_edid_free().
