-    <para>To get the current tuner or modulator radio frequency
-applications set the <structfield>tuner</structfield> field of a
-&v4l2-frequency; to the respective tuner or modulator number (only
-input devices have tuners, only output devices have modulators), zero
-out the <structfield>reserved</structfield> array and
-call the <constant>VIDIOC_G_FREQUENCY</constant> ioctl with a pointer
-to this structure. The driver stores the current frequency in the
-<structfield>frequency</structfield> field.</para>
-
-    <para>To change the current tuner or modulator radio frequency
-applications initialize the <structfield>tuner</structfield>,
-<structfield>type</structfield> and
-<structfield>frequency</structfield> fields, and the
-<structfield>reserved</structfield> array of a &v4l2-frequency; and
-call the <constant>VIDIOC_S_FREQUENCY</constant> ioctl with a pointer
-to this structure. When the requested frequency is not possible the
-driver assumes the closest possible value. However
-<constant>VIDIOC_S_FREQUENCY</constant> is a write-only ioctl, it does
-not return the actual new frequency.</para>
