The :ref:`V4L2_CID_LINK_FREQ <v4l2-cid-link-freq>` control is used to tell the
receiver the frequency of the bus (i.e. it is not the same as the symbol rate).
+Drivers that do not have user-configurable link frequency should report it

+field of struct v4l2_mbus_config, instead of through controls.
