2 * A driver for the AverMedia MR 800 USB FM radio. This device plugs
3 * into both the USB and an analog audio input, so this thing
4 * only deals with initialization and frequency setting, the
5 * audio data has to be handled by a sound driver.

21 * Big thanks to authors and contributors of dsbr100.c and radio-si470x.c
22 *
23 * When work was looked pretty good, i discover this:
24 * http://av-usbradio.sourceforge.net/index.php
25 * http://sourceforge.net/projects/av-usbradio/
26 * Latest release of theirs project was in 2005.
27 * Probably, this driver could be improved through using their
28 * achievements (specifications given).
29 * Also, Faidon Liambotis <paravoid@debian.org> wrote nice driver for this radio
30 * in 2007. He allowed to use his driver to improve current mr800 radio driver.
31 * http://www.spinics.net/lists/linux-usb-devel/msg10109.html
32 *
33 * Version 0.01: First working version.
34 * It's required to blacklist AverMedia USB Radio
35 * in usbhid/hid-quirks.c
36 * Version 0.10: A lot of cleanups and fixes: unpluging the device,
37 * few mutex locks were added, codinstyle issues, etc.
38 * Added stereo support. Thanks to
39 * Douglas Schilling Landgraf <dougsland@gmail.com> and
40 * David Ellingsworth <david@identd.dyndns.org>
41 * for discussion, help and support.
42 * Version 0.11: Converted to v4l2_device.
43 *
44 * Many things to do:
45 * - Correct power management of device (suspend & resume)
46 * - Add code for scanning and smooth tuning
47 * - Add code for sensitivity value
48 * - Correct mistakes
49 * - In Japan another FREQ_MIN and FREQ_MAX
