Linux-2.6.12-rc2
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!

+ * Fine tuning/VIDEO_TUNER_LOW
+ * Range expanded to 87-108 MHz (from 87.9-107.8)
+ *
+ * Notable changes from the original source:
+ * - includes stripped down to the essentials
+ * - for loops used as delays replaced with udelay()
+ * - #defines removed, changed to static values
+ * - tuning structure changed - no more character arrays, other changes

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

+/*
+ * Guillemot Maxi Radio FM 2000 PCI radio card driver for Linux
+ * (C) 2001 Dimitromanolakis Apostolos <apdim@grecian.net>
+ *
+ * Based in the radio Maestro PCI driver. Actually it uses the same chip
+ * for radio but different pci controller.
+ *
+ * I didn't have any specs I reversed engineered the protocol from
+ * the windows driver (radio.dll).
+ *
+ * The card uses the TEA5757 chip that includes a search function but it
+ * is useless as I haven't found any way to read back the frequency. If
+ * anybody does please mail me.
+ *
+ * For the pdf file see:
+ * http://www.semiconductors.philips.com/pip/TEA5757H/V1
+ *
+ *
+ * CHANGES:
+ * 0.75b
+ * - better pci interface thanks to Francois Romieu <romieu@cogenit.fr>
+ *
+ * 0.75
+ * - tiding up
+ * - removed support for multiple devices as it didn't work anyway
+ *
+ * BUGS:
+ * - card unmutes if you change frequency
+ *

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

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

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