documentation.

-    <para>This ioctl is <emphasis role="bold">deprecated</emphasis>.
-    New drivers and applications should use &VIDIOC-QUERY-DV-TIMINGS; instead.
-    </para>
-
-    <para>The hardware may be able to detect the current DV preset
-automatically, similar to sensing the video standard. To do so, applications
-call <constant> VIDIOC_QUERY_DV_PRESET</constant> with a pointer to a
-&v4l2-dv-preset; type. Once the hardware detects a preset, that preset is
-returned in the preset field of &v4l2-dv-preset;. If the preset could not be
-detected because there was no signal, or the signal was unreliable, or the
-signal did not map to a supported preset, then the value V4L2_DV_INVALID is
-returned.</para>
