  Add the get_mbus_config() as the means for conveying the link frequency
towards the receiver drivers.

 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).
+On devices where the link frequency isn't configurable, the link_freq field of
+struct v4l2_mbus_config is recommended over controls for conveying the link
+frequency to the downstream driver in the pipeline.
