-    <para>This ioctl lets applications enumerate available frame intervals on a
-    given sub-device pad. Frame intervals only makes sense for sub-devices that
-    can control the frame period on their own. This includes, for instance,
-    image sensors and TV tuners.</para>
-
-    <para>For the common use case of image sensors, the frame intervals
-    available on the sub-device output pad depend on the frame format and size
-    on the same pad. Applications must thus specify the desired format and size
-    when enumerating frame intervals.</para>
-
-    <para>To enumerate frame intervals applications initialize the
-    <structfield>index</structfield>, <structfield>pad</structfield>,
-    <structfield>which</structfield>, <structfield>code</structfield>,
-    <structfield>width</structfield> and <structfield>height</structfield>
-    fields of &v4l2-subdev-frame-interval-enum; and call the
-    <constant>VIDIOC_SUBDEV_ENUM_FRAME_INTERVAL</constant> ioctl with a pointer
-    to this structure. Drivers fill the rest of the structure or return
-    an &EINVAL; if one of the input fields is invalid. All frame intervals are
-    enumerable by beginning at index zero and incrementing by one until
-    <errorcode>EINVAL</errorcode> is returned.</para>
-
-    <para>Available frame intervals may depend on the current 'try' formats
-    at other pads of the sub-device, as well as on the current active links. See
-    &VIDIOC-SUBDEV-G-FMT; for more information about the try formats.</para>
-
-    <para>Sub-devices that support the frame interval enumeration ioctl should
-    implemented it on a single pad only. Its behaviour when supported on
-    multiple pads of the same sub-device is not defined.</para>
