+Common selection definitions
+============================
+
+While the :ref:`V4L2 selection API <selection-api>` and
+:ref:`V4L2 subdev selection APIs <v4l2-subdev-selections>` are very
+similar, there's one fundamental difference between the two. On
+sub-device API, the selection rectangle refers to the media bus format,
+and is bound to a sub-device's pad. On the V4L2 interface the selection
+rectangles refer to the in-memory pixel format.
+
+This section defines the common definitions of the selection interfaces
+on the two APIs.
