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
+through the ``.get_mbus_config()`` subdev pad operation, in the ``link_freq``
+field of struct v4l2_mbus_config, instead of through controls.
+
``.enable_streams()`` and ``.disable_streams()`` callbacks

Add the get_mbus_config() as the means for conveying the link frequency towards the receiver drivers. Signed-off-by: Sakari Ailus <sakari.ailus@linux.intel.com> --- Documentation/driver-api/media/tx-rx.rst | 4 ++++ 1 file changed, 4 insertions(+)
