Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!

12 *
13 * Notes on the hardware (reverse engineered from other peoples'
14 * reverse engineering of AIMS' code :-)
15 *
16 * Frequency control is done digitally -- ie out(port,encodefreq(95.8));
17 *
18 * The signal strength query is unsurprisingly inaccurate. And it seems
19 * to indicate that (on my card, at least) the frequency setting isn't
20 * too great. (I have to tune up .025MHz from what the freq should be
21 * to get a report that the thing is tuned.)
22 *
23 * Volume control is (ugh) analogue:
24 * out(port, start_increasing_volume);
25 * wait(a_wee_while);
26 * out(port, stop_changing_the_volume);

1/* radio-aztech.c - Aztech radio card driver for Linux 2.2
2 *
3 * Adapted to support the Video for Linux API by
4 * Russell Kroll <rkroll@exploits.org>. Based on original tuner code by:
5 *
6 * Quay Ly
7 * Donald Song
8 * Jason Lewis (jlewis@twilight.vtc.vsc.edu)
9 * Scott McGrath (smcgrath@twilight.vtc.vsc.edu)
10 * William McGrath (wmcgrath@twilight.vtc.vsc.edu)
11 *
12 * The basis for this code may be found at http://bigbang.vtc.vsc.edu/fmradio/
13 * along with more information on the card itself.
14 *
15 * History:
16 * 1999-02-24 Russell Kroll <rkroll@exploits.org>
17 * Fine tuning/VIDEO_TUNER_LOW
18 * Range expanded to 87-108 MHz (from 87.9-107.8)
19 *
20 * Notable changes from the original source:
21 * - includes stripped down to the essentials
22 * - for loops used as delays replaced with udelay()
23 * - #defines removed, changed to static values
24 * - tuning structure changed - no more character arrays, other changes

1/* radio-cadet.c - A video4linux driver for the ADS Cadet AM/FM Radio Card
2 *
3 * by Fred Gleason <fredg@wava.com>
4 * Version 0.3.3
5 *
6 * (Loosely) based on code for the Aztech radio card by
7 *
8 * Russell Kroll (rkroll@exploits.org)
9 * Quay Ly
10 * Donald Song
11 * Jason Lewis (jlewis@twilight.vtc.vsc.edu)
12 * Scott McGrath (smcgrath@twilight.vtc.vsc.edu)
13 * William McGrath (wmcgrath@twilight.vtc.vsc.edu)
14 *
15 * History:
16 * 2000-04-29 Russell Kroll <rkroll@exploits.org>
17 * Added ISAPnP detection for Linux 2.3/2.4
18 *
19 * 2001-01-10 Russell Kroll <rkroll@exploits.org>
20 * Removed dead CONFIG_RADIO_CADET_PORT code
21 * PnP detection on load is now default (no args necessary)
22 *
23 * 2002-01-17 Adam Belay <ambx1@neo.rr.com>
24 * Updated to latest pnp code
25 *
26 * 2003-01-31 Alan Cox <alan@redhat.com>
27 * Cleaned up locking, delay code, general odds and ends

1/* Maestro PCI sound card radio driver for Linux support
2 * (c) 2000 A. Tlalka, atlka@pg.gda.pl
3 * Notes on the hardware
4 *
5 * + Frequency control is done digitally
6 * + No volume control - only mute/unmute - you have to use Aux line volume
7 * control on Maestro card to set the volume
8 * + Radio status (tuned/not_tuned and stereo/mono) is valid some time after
9 * frequency setting (>100ms) and only when the radio is unmuted.
10 * version 0.02
11 * + io port is automatically detected - only the first radio is used
12 * version 0.03
13 * + thread access locking additions
14 * version 0.04
15 * + code improvements
16 * + VIDEO_TUNER_LOW is permanent

1/*
2 * Guillemot Maxi Radio FM 2000 PCI radio card driver for Linux
3 * (C) 2001 Dimitromanolakis Apostolos <apdim@grecian.net>
4 *
5 * Based in the radio Maestro PCI driver. Actually it uses the same chip
6 * for radio but different pci controller.
7 *
8 * I didn't have any specs I reversed engineered the protocol from
9 * the windows driver (radio.dll).
10 *
11 * The card uses the TEA5757 chip that includes a search function but it
12 * is useless as I haven't found any way to read back the frequency. If
13 * anybody does please mail me.
14 *
15 * For the pdf file see:
16 * http://www.semiconductors.philips.com/pip/TEA5757H/V1
17 *
18 *
19 * CHANGES:
20 * 0.75b
21 * - better pci interface thanks to Francois Romieu <romieu@cogenit.fr>
22 *
23 * 0.75
24 * - tiding up
25 * - removed support for multiple devices as it didn't work anyway
26 *
27 * BUGS:
28 * - card unmutes if you change frequency
29 *

11 *
12 * Frequency control is done digitally -- ie out(port,encodefreq(95.8));
13 * No volume control - only mute/unmute - you have to use line volume

1/* SF16FMR2 radio driver for Linux radio support
2 * heavily based on fmi driver...
3 * (c) 2000-2002 Ziglio Frediano, freddy77@angelfire.com
4 *
5 * Notes on the hardware
6 *
7 * Frequency control is done digitally -- ie out(port,encodefreq(95.8));
8 * No volume control - only mute/unmute - you have to use line volume
9 *
10 * For read stereo/mono you must wait 0.1 sec after set frequency and
11 * card unmuted so I set frequency on unmute
12 * Signal handling seem to work only on autoscanning (not implemented)

1/* Terratec ActiveRadio ISA Standalone card driver for Linux radio support
2 * (c) 1999 R. Offermanns (rolf@offermanns.de)
3 * based on the aimslab radio driver from M. Kirkwood
4 * many thanks to Michael Becker and Friedhelm Birth (from TerraTec)
5 *
6 *
7 * History:
8 * 1999-05-21 First preview release
9 *
10 * Notes on the hardware:
11 * There are two "main" chips on the card:
12 * - Philips OM5610 (http://www-us.semiconductors.philips.com/acrobat/datasheets/OM5610_2.pdf)
13 * - Philips SAA6588 (http://www-us.semiconductors.philips.com/acrobat/datasheets/SAA6588_1.pdf)
14 * (you can get the datasheet at the above links)
15 *
16 * Frequency control is done digitally -- ie out(port,encodefreq(95.8));
17 * Volume Control is done digitally
18 *
19 * there is a I2C controlled RDS decoder (SAA6588) onboard, which i would like to support someday
20 * (as soon i have understand how to get started :)
21 * If you can help me out with that, please contact me!!
22 *

1/* Typhoon Radio Card driver for radio support
2 * (c) 1999 Dr. Henrik Seidel <Henrik.Seidel@gmx.de>
3 *
4 * Card manufacturer:
5 * http://194.18.155.92/idc/prod2.idc?nr=50753&lang=e
6 *
7 * Notes on the hardware
8 *
9 * This card has two output sockets, one for speakers and one for line.
10 * The speaker output has volume control, but only in four discrete
11 * steps. The line output has neither volume control nor mute.
12 *
13 * The card has auto-stereo according to its manual, although it all
14 * sounds mono to me (even with the Win/DOS drivers). Maybe it's my
15 * antenna - I really don't know for sure.
16 *
17 * Frequency control is done digitally.
18 *
19 * Volume control is done digitally, but there are only four different
20 * possible values. So you should better always turn the volume up and
21 * use line control. I got the best results by connecting line output
22 * to the sound card microphone input. For such a configuration the
23 * volume control has no effect, since volume control only influences
24 * the speaker output.
25 *
26 * There is no explicit mute/unmute. So I set the radio frequency to a
27 * value where I do expect just noise and turn the speaker volume down.
28 * The frequency change is necessary since the card never seems to be
29 * completely silent.

3 *
4 * BUGS
5 * Due to the inconsistency in reading from the signal flags
6 * it is difficult to get an accurate tuned signal.
7 *
8 * It seems that the card is not linear to 0 volume. It cuts off
9 * at a low volume, and it is not possible (at least I have not found)
10 * to get fine volume control over the low volume range.
11 *
12 * Some code derived from code by Romolo Manfredini
13 * romolo@bicnet.it
14 *
15 * 1999-05-06 - (C. van Schaik)
16 * - Make signal strength and stereo scans
17 * kinder to cpu while in delay
18 * 1999-01-05 - (C. van Schaik)
19 * - Changed tuning to 1/160Mhz accuracy
20 * - Added stereo support
21 * (card defaults to stereo)
22 * (can explicitly force mono on the card)
23 * (can detect if station is in stereo)
24 * - Added unmute function
25 * - Reworked ioctl functions
26 * 2002-07-15 - Fix Stereo typo
