*
* 1. Under stress-testing, it has been observed that the PCIe link
* goes down, without reason. Therefore, the driver takes special care
* to allow device hot-unplugging.
*
* 2. TW686X devices are capable of setting a few different DMA modes,
* including: scatter-gather, field and frame modes. However,
* under stress testings it has been found that the machine can
* freeze completely if DMA registers are programmed while streaming
* is active.
*
* Therefore, driver implements a dma_mode called 'memcpy' which
* avoids cycling the DMA buffers, and insteads allocates extra DMA buffers
* and then copies into vmalloc'ed user buffers.
*
* In addition to this, when streaming is on, the driver tries to access
* hardware registers as infrequently as possible. This is done by using
* a timer to limit the rate at which DMA is reset on DMA channels error.

* of course means that if we set up the
* bottom field in the above code that we'll
* actually skip a field. But that's OK.
* Having processed only a single buffer this
* time, then the next time around the first
* available buffer should be for a top field.
* That will then cause us here to set up a
* top then a bottom field in the normal way.
* The alternative to this understanding is
* that we set up the second available buffer
* as a top field, but that's out of order
* since this driver always processes the top
* field first - the effect will be the two
* buffers being returned in the wrong order,
* with the second buffer also being delayed
* by one field time (owing to the fifo nature
* of videobuf). Worse still, we'll be stuck
* doing fields out of order now every time
* until something else causes a field to be
* dropped. By effectively forcing a field to
* drop this way then we always get back into
* sync within a single frame time. (Out of
* order fields can screw up deinterlacing
* algorithms.) */

*
* The CS16 (available on eBay cheap) is a PCI board with four Fusion
* 878A chips, a PCI bridge, an Atmel microcontroller, four sync separator
* chips, ten eight input analog multiplexors, a not chip and a few
* other components.
*
* 16 inputs on a secondary bracket are provided and can be selected
* from each of the four capture chips. Two of the eight input
* multiplexors are used to select from any of the 16 input signals.
*
* Unsupported hardware capabilities:
* . A video output monitor on the secondary bracket can be selected from
* one of the 878A chips.
* . Another passthrough but I haven't spent any time investigating it.
* . Digital I/O (logic level connected to GPIO) is available from an
* onboard header.
*
* The on chip input mux should always be set to 2.
* GPIO[16:19] - Video input selection
* GPIO[0:3] - Video output monitor select (only available from one 878A)
* GPIO[?:?] - Digital I/O.
*
* There is an ATMEL microcontroller with an 8031 core on board. I have not
* determined what function (if any) it provides. With the microcontroller
* and sync separator chips a guess is that it might have to do with video
* switching and maybe some digital I/O.

* The analog switch is controlled by the "master", but the detection order
* of the four BT878A chips is in an order which I just don't understand.
* The "master" is actually the second controller to be detected. The
* logic on the board uses logical numbers for the 4 controllers, but
* those numbers are different from the detection sequence. When working
* with the analog switch, we need to "map" from the detection sequence
* over to the board's logical controller number. This mapping sequence
* is {3, 0, 2, 1}, i.e. the first controller to be detected is logical
* unit 3, the second (which is the master) is logical unit 0, etc.

* the switch. A STROBE bit (gpio bit 8) latches the data value into the
* specified address. The idea is to set the address and data, then bring

/*
* Guillemot Maxi Radio FM 2000 PCI radio card driver for Linux
* (C) 2001 Dimitromanolakis Apostolos <[email protected]>
*
* 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.nxp.com/acrobat_download2/expired_datasheets/TEA5757_5759_3.pdf
*
*
* CHANGES:
* 0.75b
* - better pci interface thanks to Francois Romieu <[email protected]>
*
* 0.75 Sun Feb 4 22:51:27 EET 2001
* - tiding up
* - removed support for multiple devices as it didn't work anyway
*
* BUGS:
* - card unmutes if you change frequency
*
* (c) 2006, 2007 by Mauro Carvalho Chehab <[email protected]>:
* - Conversion to V4L2 API
* - Uses video_ioctl2 for parsing and to add debug support

/* Terratec ActiveRadio ISA Standalone card driver for Linux radio support
* (c) 1999 R. Offermanns ([email protected])
* 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
*
* Converted to the radio-isa framework by Hans Verkuil <[email protected]>
* Converted to V4L2 API by Mauro Carvalho Chehab <[email protected]>

* Zoltrix Radio Plus driver
* Copyright 1998 C. van Schaik <[email protected]>
*
* 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
* [email protected]
*
* 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
*
* 2006-07-24 - Converted to V4L2 API
* by Mauro Carvalho Chehab <[email protected]>
*
* Converted to the radio-isa framework by Hans Verkuil <[email protected]>
*
* Note that this is the driver for the Zoltrix Radio Plus.
* This driver does not work for the Zoltrix Radio Plus 108 or the
* Zoltrix Radio Plus for Windows.

/* Typhoon Radio Card driver for radio support
* (c) 1999 Dr. Henrik Seidel <[email protected]>
*
* 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.
*

/*
* Big thanks to authors and contributors of dsbr100.c and radio-si470x.c
*
* When work was looked pretty good, i discover this:
* http://av-usbradio.sourceforge.net/index.php
* http://sourceforge.net/projects/av-usbradio/
* Latest release of theirs project was in 2005.
* Probably, this driver could be improved through using their
* achievements (specifications given).
* Also, Faidon Liambotis <[email protected]> wrote nice driver for this radio
* in 2007. He allowed to use his driver to improve current mr800 radio driver.
* http://www.spinics.net/lists/linux-usb-devel/msg10109.html
*
* Version 0.01: First working version.
* It's required to blacklist AverMedia USB Radio
* in usbhid/hid-quirks.c
* Version 0.10: A lot of cleanups and fixes: unpluging the device,
* few mutex locks were added, codinstyle issues, etc.
* Added stereo support. Thanks to
* Douglas Schilling Landgraf <[email protected]> and
* David Ellingsworth <[email protected]>
* for discussion, help and support.
* Version 0.11: Converted to v4l2_device.
*
* Many things to do:
* - Correct power management of device (suspend & resume)
* - Add code for scanning and smooth tuning
* - Add code for sensitivity value
* - Correct mistakes
* - In Japan another FREQ_MIN and FREQ_MAX

/* A driver for the D-Link DSB-R100 USB radio and Gemtek USB Radio 21.
* The device plugs into both the USB and an analog audio input, so this thing
* only deals with initialisation and frequency setting, the
* audio data has to be handled by a sound driver.
*
* Major issue: I can't find out where the device reports the signal
* strength, and indeed the windows software appearantly just looks
* at the stereo indicator as well. So, scanning will only find
* stereo stations. Sad, but I can't help it.
*
* Also, the windows program sends oodles of messages over to the
* device, and I couldn't figure out their meaning. My suspicion
* is that they don't have any:-)
*
* You might find some interesting stuff about this module at
* http://unimut.fsk.uni-heidelberg.de/unimut/demi/dsbr
*
* Fully tested with the Keene USB FM Transmitter and the v4l2-compliance tool.
