+cx8800 release notes
+====================
+
+This is a v4l2 device driver for the cx2388x chip.
+
+
+current status
+==============
+
+video
+	- Basically works.
+	- Some minor image quality glitches.
+	- Eed and blue are swapped sometimes for not-yet known
+	  reasons (seems to depend on the image size, try to resize
+	  your tv app window as workaround ...).
+	- For now only capture, overlay support isn't completed yet.
+
+audio
+	- The chip specs for the on-chip TV sound decoder are next
+	  to useless :-/
+	- Neverless the builtin TV sound decoder starts working now.
+	- Most tuner chips do provide mono sound, which may or may not
+	  be useable depending on the board design.  With the Hauppauge
+	  cards it works, so there is mono sound available as fallback.
+	- audio data dma (i.e. recording without loopback cable to the
+	  sound card), but there is no code yet ...
+
+vbi
+	- some code present.  Doesn't crash any more, but also doesn't
+	  work yet ...
+
+
+how to add support for new cards
+================================
+
+The driver needs some config info for the TV cards.  This stuff is in
+cx88-cards.c.  If the driver doesn't work well you likely need a new
+entry for your card in that file.  Check the kernel log (using dmesg)
+to see whenever the driver knows your card or not.  There is a line
+like this one:
+
+	cx8800[0]: subsystem: 0070:3400, board: Hauppauge WinTV \
+		34xxx models [card=1,autodetected]
+
+If your card is listed as "board: UNKNOWN/GENERIC" it is unknown to
+the driver.  What to do then?
+
+ (1) Try upgrading to the latest snapshot, maybe it has been added
+     meanwhile.
+ (2) You can try to create a new entry yourself, have a look at
+     cx88-cards.c.  If that worked, mail me your changes as unified
+     diff ("diff -u").
+ (3) Or you can mail me the config information.  I need at least the
+     following informations to add the card:
+
+     * the PCI Subsystem ID ("0070:3400" from the line above,
+       "lspci -v" output is fine too).
+     * the tuner type used by the card.  You can try to find one by
+       trial-and-error using the tuner=<n> insmod option.  If you
+       know which one the card has you can also have a look at the
+       list in CARDLIST.tuner
+
+Have fun,
+
+  Gerd

+
+What is it?
+===========
+
+This is a v4l2/oss device driver for saa7130/33/34/35 based capture / TV
+boards.  See http://www.semiconductors.philips.com/pip/saa7134hl for a
+description.
+
+
+Status
+======
+
+Almost everything is working.  video, sound, tuner, radio, mpeg ts, ...
+
+As with bttv, card-specific tweaks are needed.  Check CARDLIST for a
+list of known TV cards and saa7134-cards.c for the drivers card
+configuration info.
+
+
+Build
+=====
+
+Pick up videodev + v4l2 patches from http://bytesex.org/patches/.
+Configure, build, install + boot the new kernel.  You'll need at least
+these config options:
+
+	CONFIG_I2C=m
+	CONFIG_VIDEO_DEV=m
+
+Type "make" to build the driver now.  "make install" installs the
+driver.  "modprobe saa7134" should load it.  Depending on the card you
+might have to pass card=<nr> as insmod option, check CARDLIST for
+valid choices.
+
+
+Changes / Fixes
+===============
+
+Please mail me unified diffs ("diff -u") with your changes, and don't
+forget to tell me what it changes / which problem it fixes / whatever
+it is good for ...
+
+
+Known Problems
+==============
+
+* The tuner for the flyvideos isn't detected automatically and the
+  default might not work for you depending on which version you have.
+  There is a tuner= insmod option to override the driver's default.
+
+Card Variations:
+================
+
+Cards can use either of these two crystals (xtal):
+ - 32.11 MHz -> .audio_clock=0x187de7
+ - 24.576MHz -> .audio_clock=0x200000
+(xtal * .audio_clock = 51539600)

+
+
+Suppported cards:
+Bt848/Bt848a/Bt849/Bt878/Bt879 cards
+------------------------------------
+
+All cards with Bt848/Bt848a/Bt849/Bt878/Bt879 and normal
+Composite/S-VHS inputs are supported.  Teletext and Intercast support
+(PAL only) for ALL cards via VBI sample decoding in software.
+
+Some cards with additional multiplexing of inputs or other additional
+fancy chips are only partially supported (unless specifications by the
+card manufacturer are given).  When a card is listed here it isn't
+necessarily fully supported.
+
+All other cards only differ by additional components as tuners, sound
+decoders, EEPROMs, teletext decoders ...
+
+
+Unsupported Cards: 
+------------------
+
+Cards with Zoran (ZR) or Philips (SAA) or ISA are not supported by
+this driver.
+
+
+MATRIX Vision
+-------------
+
+MV-Delta
+- Bt848A
+- 4 Composite inputs, 1 S-VHS input (shared with 4th composite)
+- EEPROM
+
+http://www.matrix-vision.de/
+
+This card has no tuner but supports all 4 composite (1 shared with an
+S-VHS input) of the Bt848A.
+Very nice card if you only have satellite TV but several tuners connected
+to the card via composite.
+
+Many thanks to Matrix-Vision for giving us 2 cards for free which made
+Bt848a/Bt849 single crytal operation support possible!!!
+
+
+
+Miro/Pinnacle PCTV
+------------------
+
+- Bt848 
+  some (all??) come with 2 crystals for PAL/SECAM and NTSC 
+- PAL, SECAM or NTSC TV tuner (Philips or TEMIC)
+- MSP34xx sound decoder on add on board
+  decoder is supported but AFAIK does not yet work 
+  (other sound MUX setting in GPIO port needed??? somebody who fixed this???)
+- 1 tuner, 1 composite and 1 S-VHS input
+- tuner type is autodetected
+
+http://www.miro.de/
+http://www.miro.com/
+
+
+Many thanks for the free card which made first NTSC support possible back
+in 1997!
+
+
+Hauppauge Win/TV pci
+--------------------
+
+There are many different versions of the Hauppauge cards with different 
+tuners (TV+Radio ...), teletext decoders.
+Note that even cards with same model numbers have (depending on the revision)
+different chips on it.
+
+- Bt848 (and others but always in 2 crystal operation???)
+  newer cards have a Bt878
+- PAL, SECAM, NTSC or tuner with or without Radio support
+
+e.g.:
+  PAL: 
+  TDA5737: VHF, hyperband and UHF mixer/oscillator for TV and VCR 3-band tuners
+  TSA5522: 1.4 GHz I2C-bus controlled synthesizer, I2C 0xc2-0xc3
+  
+  NTSC:
+  TDA5731: VHF, hyperband and UHF mixer/oscillator for TV and VCR 3-band tuners
+  TSA5518: no datasheet available on Philips site
+- Philips SAA5246 or SAA5284 ( or no) Teletext decoder chip	
+  with buffer RAM (e.g. Winbond W24257AS-35: 32Kx8 CMOS static RAM)
+  SAA5246 (I2C 0x22) is supported
+- 256 bytes EEPROM: Microchip 24LC02B or Philips 8582E2Y 
+  with configuration information
+  I2C address 0xa0 (24LC02B also responds to 0xa2-0xaf)
+- 1 tuner, 1 composite and (depending on model) 1 S-VHS input
+- 14052B: mux for selection of sound source
+- sound decoder: TDA9800, MSP34xx (stereo cards)

+     CPH0x8: PAL-B/H 
+     CPH0x9: PAL-M/M
+
+  CPH03x was often sold as "TV capturer".
+
+  Identifying:
+  1) 878 cards can be identified by PCI Subsystem-ID:
+      144f:3000 = CPH06x
+      144F:3002 = CPH05x w/ FM
+      144F:3005 = CPH06x_LC (w/o remote control)
+  1) The cards have a sticker with "CPH"-model on the back.
+  2) These cards have a number printed on the PCB just above the tuner metal box:
+      "80-CP2000300-x" = CPH03X
+      "80-CP2000500-x" = CPH05X
+      "80-CP2000600-x" = CPH06X / CPH06x_LC
+
+  Askey sells these cards as "Magic TView series", Brand "MagicXpress".
+  Other OEM often call these "Tview", "TView99" or else.
+
+Lifeview Flyvideo Series:
+-------------------------
+  The naming of these series differs in time and space.
+
+  Identifying:
+  1) Some models can be identified by PCI subsystem ID:
+      1852:1852 = Flyvideo 98 FM
+      1851:1850 = Flyvideo 98
+      1851:1851 = Flyvideo 98 EZ (capture only)
+  2) There is a print on the PCB:
+      LR25       = Flyvideo (Zoran ZR36120, SAA7110A)
+      LR26 Rev.N = Flyvideo II (Bt848)
+           Rev.O = Flyvideo II (Bt878)
+      LR37 Rev.C = Flyvideo EZ (Capture only, ZR36120 + SAA7110)
+      LR38 Rev.A1= Flyvideo II EZ (Bt848 capture only)
+      LR50 Rev.Q = Flyvideo 98 (w/eeprom and PCI subsystem ID)
+           Rev.W = Flyvideo 98 (no eeprom)
+      LR51 Rev.E = Flyvideo 98 EZ (capture only)
+      LR90       = Flyvideo 2000 (Bt878)
+		   Flyvideo 2000S (Bt878) w/Stereo TV (Package incl. LR91 daughterboard)
+      LR91       = Stereo daughter card for LR90
+      LR97       = Flyvideo DVBS
+      LR99 Rev.E = Low profile card for OEM integration (only internal audio!) bt878
+      LR136	 = Flyvideo 2100/3100 (Low profile, SAA7130/SAA7134)
+      LR137      = Flyvideo DV2000/DV3000 (SAA7130/SAA7134 + IEEE1394)
+      LR138 Rev.C= Flyvideo 2000 (SAA7130)
+	        or Flyvideo 3000 (SAA7134) w/Stereo TV
+		   These exist in variations w/FM and w/Remote sometimes denoted
+		   by suffixes "FM" and "R".
+
+      Lifeview.com.tw states (Feb. 2002):
+      "The FlyVideo2000 and FlyVideo2000s product name have renamed to FlyVideo98."
+      Their Bt8x8 cards are listed as discontinued.
+      Flyvideo 2000S was probably sold as Flyvideo 3000 in some contries(Europe?).
+      The new Flyvideo 2000/3000 are SAA7130/SAA7134 based. 
+
+  "Flyvideo II" had been the name for the 848 cards, nowadays (in Germany)
+  this name is re-used for LR50 Rev.W.
+  The Lifeview website mentioned Flyvideo III at some time, but such a card
+  has not yet been seen (perhaps it was the german name for LR90 [stereo]).
+  These cards are sold by many OEMs too.
+
+  FlyVideo A2 (Elta 8680)= LR90 Rev.F (w/Remote, w/o FM, stereo TV by tda9821) {Germany}
+  Lifeview 3000 (Elta 8681) as sold by Plus(April 2002), Germany = LR138 w/ saa7134

+				see README.quirks for details on these two.
+
+		bigendian=n	Set the endianness of the gfx framebuffer.
+				Default is native endian.
+		fieldnr=0/1	Count fields.  Some TV descrambling software
+				needs this, for others it only generates
+				50 useless IRQs/sec.  default is 0 (off).
+		autoload=0/1	autoload helper modules (tuner, audio).
+				default is 1 (on).
+		bttv_verbose=0/1/2  verbose level (at insmod time, while
+				looking at the hardware).  default is 1.
+		bttv_debug=0/1	debug messages (for capture).
+				default is 0 (off).
+		irq_debug=0/1	irq handler debug messages.
+				default is 0 (off).
+		gbuffers=2-32	number of capture buffers for mmap'ed capture.
+				default is 4.
+		gbufsize=	size of capture buffers. default and
+				maximum value is 0x208000 (~2MB)
+		no_overlay=0	Enable overlay on broken hardware.  There
+				are some chipsets (SIS for example) which
+				are known to have problems with the PCI DMA
+				push used by bttv.  bttv will disable overlay
+				by default on this hardware to avoid crashes.
+				With this insmod option you can override this.
+		automute=0/1	Automatically mutes the sound if there is
+				no TV signal, on by default.  You might try
+				to disable this if you have bad input signal
+				quality which leading to unwanted sound
+				dropouts.
+		chroma_agc=0/1	AGC of chroma signal, off by default.
+		adc_crush=0/1	Luminance ADC crush, on by default.
+
+		bttv_gpio=0/1
+		gpiomask=
+		audioall=
+		audiomux=
+				See Sound-FAQ for a detailed description.
+
+	remap, card, radio and pll accept up to four comma-separated arguments
+	(for multiple boards).
+
+tuner.o
+	The tuner driver.  You need this unless you want to use only
+	with a camera or external tuner ...
+
+	insmod args:
+		debug=1		print some debug info to the syslog
+		type=n		type of the tuner chip. n as follows:
+				see CARDLIST for a complete list.
+		pal=[bdgil]	select PAL variant (used for some tuners
+				only, important for the audio carrier).
+
+tvmixer.o
+	registers a mixer device for the TV card's volume/bass/treble
+	controls (requires a i2c audio control chip like the msp3400).
+
+	insmod args:
+		debug=1		print some debug info to the syslog.
+		devnr=n		allocate device #n (0 == /dev/mixer,
+				1 = /dev/mixer1, ...), default is to
+				use the first free one.
+
+tvaudio.o
+	new, experimental module which is supported to provide a single
+	driver for all simple i2c audio control chips (tda/tea*).
+
+	insmod args:
+		tda8425  = 1	enable/disable the support for the
+		tda9840  = 1	various chips.
+		tda9850  = 1	The tea6300 can't be autodetected and is
+		tda9855  = 1	therefore off by default, if you have
+		tda9873  = 1	this one on your card (STB uses these)
+		tda9874a = 1	you have to enable it explicitly.
+		tea6300  = 0	The two tda985x chips use the same i2c
+		tea6420  = 1	address and can't be disturgished from
+		pic16c54 = 1	each other, you might have to disable
+				the wrong one.
+		debug = 1	print debug messages
+
+	insmod args for tda9874a:
+		tda9874a_SIF=1/2	select sound IF input pin (1 or 2)
+					(default is pin 1)
+		tda9874a_AMSEL=0/1	auto-mute select for NICAM (default=0)
+					Please read note 3 below!
+		tda9874a_STD=n		select TV sound standard (0..8):
+					0 - A2, B/G
+					1 - A2, M (Korea)
+					2 - A2, D/K (1)
+					3 - A2, D/K (2)
+					4 - A2, D/K (3)
+					5 - NICAM, I
+					6 - NICAM, B/G
+					7 - NICAM, D/K (default)
+					8 - NICAM, L
+
+	Note 1: tda9874a supports both tda9874h (old) and tda9874a (new) chips.
+	Note 2: tda9874h/a and tda9875 (which is supported separately by
+	tda9875.o) use the same i2c address so both modules should not be
+	used at the same time.
+	Note 3: Using tda9874a_AMSEL option depends on your TV card design!
+		AMSEL=0: auto-mute will switch between NICAM sound
+			 and the sound on 1st carrier (i.e. FM mono or AM).
+		AMSEL=1: auto-mute will switch between NICAM sound
+			 and the analog mono input (MONOIN pin).
+	If tda9874a decoder on your card has MONOIN pin not connected, then
+	use only tda9874_AMSEL=0 or don't specify this option at all.
+	For example:
+	  card=65 (FlyVideo 2000S) - set AMSEL=1 or AMSEL=0
+	  card=72 (Prolink PV-BT878P rev.9B) - set AMSEL=0 only
+
+msp3400.o
+	The driver for the msp34xx sound processor chips. If you have a
+	stereo card, you probably want to insmod this one.
+
+	insmod args:
+		debug=1/2	print some debug info to the syslog,
+				2 is more verbose.
+		simple=1	Use the "short programming" method.  Newer
+				msp34xx versions support this.  You need this
+				for dbx stereo.  Default is on if supported by
+				the chip.
+		once=1		Don't check the TV-stations Audio mode
+				every few seconds, but only once after
+				channel switches.
+		amsound=1	Audio carrier is AM/NICAM at 6.5 Mhz.  This
+				should improve things for french people, the
+				carrier autoscan seems to work with FM only...
+
+tea6300.o - OBSOLETE (use tvaudio instead)
+	The driver for the tea6300 fader chip.  If you have a stereo
+	card and the msp3400.o doesn't work, you might want to try this
+	one.  This chip is seen on most STB TV/FM cards (usually from
+	Gateway OEM sold surplus on auction sites).
+
+	insmod args:
+		debug=1		print some debug info to the syslog.
+
+tda8425.o - OBSOLETE (use tvaudio instead)
+	The driver for the tda8425 fader chip.  This driver used to be
+	part of bttv.c, so if your sound used to work but does not
+	anymore, try loading this module.
+
+	insmod args:
+		debug=1		print some debug info to the syslog.
+
+tda985x.o - OBSOLETE (use tvaudio instead)
+	The driver for the tda9850/55 audio chips.
+
+	insmod args:
+		debug=1		print some debug info to the syslog.
+		chip=9850/9855	set the chip type.

+
+Release notes for bttv
+======================
+
+You'll need at least these config options for bttv:
+	CONFIG_I2C=m
+	CONFIG_I2C_ALGOBIT=m
+	CONFIG_VIDEO_DEV=m
+
+The latest bttv version is available from http://bytesex.org/bttv/
+
+
+Make bttv work with your card
+-----------------------------
+
+Just try "modprobe bttv" and see if that works.
+
+If it doesn't bttv likely could not autodetect your card and needs some
+insmod options.  The most important insmod option for bttv is "card=n"
+to select the correct card type.  If you get video but no sound you've
+very likely specified the wrong (or no) card type.  A list of supported
+cards is in CARDLIST.bttv
+
+If bttv takes very long to load (happens sometimes with the cheap
+cards which have no tuner), try adding this to your modules.conf:
+	options i2c-algo-bit bit_test=1
+
+For the WinTV/PVR you need one firmware file from the driver CD:
+hcwamc.rbf.  The file is in the pvr45xxx.exe archive (self-extracting
+zip file, unzip can unpack it).  Put it into the /etc/pvr directory or
+use the firm_altera=<path> insmod option to point the driver to the
+location of the file.
+
+If your card isn't listed in CARDLIST.bttv or if you have trouble making
+audio work, you should read the Sound-FAQ.
+
+
+Autodetecting cards
+-------------------
+
+bttv uses the PCI Subsystem ID to autodetect the card type.  lspci lists
+the Subsystem ID in the second line, looks like this:
+
+00:0a.0 Multimedia video controller: Brooktree Corporation Bt878 (rev 02)
+        Subsystem: Hauppauge computer works Inc. WinTV/GO
+        Flags: bus master, medium devsel, latency 32, IRQ 5
+        Memory at e2000000 (32-bit, prefetchable) [size=4K]
+
+only bt878-based cards can have a subsystem ID (which does not mean
+that every card really has one).  bt848 cards can't have a Subsystem
+ID and therefore can't be autodetected.  There is a list with the ID's
+in bttv-cards.c (in case you are intrested or want to mail patches
+with updates).
+
+
+Still doesn't work?
+-------------------
+
+I do NOT have a lab with 30+ different grabber boards and a
+PAL/NTSC/SECAM test signal generator at home, so I often can't
+reproduce your problems.  This makes debugging very difficult for me.
+If you have some knowledge and spare time, please try to fix this
+yourself (patches very welcome of course...)  You know: The linux
+slogan is "Do it yourself".

+bttv and sound mini howto
+=========================
+
+There are alot of different bt848/849/878/879 based boards available.
+Making video work often is not a big deal, because this is handled
+completely by the bt8xx chip, which is common on all boards.  But
+sound is handled in slightly different ways on each board.
+
+To handle the grabber boards correctly, there is a array tvcards[] in
+bttv-cards.c, which holds the informations required for each board.
+Sound will work only, if the correct entry is used (for video it often
+makes no difference).  The bttv driver prints a line to the kernel
+log, telling which card type is used.  Like this one:
+
+	bttv0: model: BT848(Hauppauge old) [autodetected]
+
+You should verify this is correct.  If it isn't, you have to pass the
+correct board type as insmod argument, "insmod bttv card=2" for
+example.  The file CARDLIST has a list of valid arguments for card.
+If your card isn't listed there, you might check the source code for
+new entries which are not listed yet.  If there isn't one for your
+card, you can check if one of the existing entries does work for you
+(just trial and error...).
+
+Some boards have an extra processor for sound to do stereo decoding
+and other nice features.  The msp34xx chips are used by Hauppauge for
+example.  If your board has one, you might have to load a helper
+module like msp3400.o to make sound work.  If there isn't one for the
+chip used on your board:  Bad luck.  Start writing a new one.  Well,
+you might want to check the video4linux mailing list archive first...
+
+Of course you need a correctly installed soundcard unless you have the
+speakers connected directly to the grabber board.  Hint: check the
+mixer settings too.  ALSA for example has everything muted by default.
+
+
+How sound works in detail
+=========================
+
+Still doesn't work?  Looks like some driver hacking is required.
+Below is a do-it-yourself description for you.
+
+The bt8xx chips have 32 general purpose pins, and registers to control
+these pins.  One register is the output enable register
+(BT848_GPIO_OUT_EN), it says which pins are actively driven by the
+bt848 chip.  Another one is the data register (BT848_GPIO_DATA), where
+you can get/set the status if these pins.  They can be used for input
+and output.
+
+Most grabber board vendors use these pins to control an external chip
+which does the sound routing.  But every board is a little different.
+These pins are also used by some companies to drive remote control
+receiver chips.  Some boards use the i2c bus instead of the gpio pins
+to connect the mux chip.
+
+As mentioned above, there is a array which holds the required
+informations for each known board.  You basically have to create a new
+line for your board.  The important fields are these two:
+
+struct tvcard
+{
+	[ ... ]
+        u32 gpiomask;
+        u32 audiomux[6]; /* Tuner, Radio, external, internal, mute, stereo */
+};
+
+gpiomask specifies which pins are used to control the audio mux chip.
+The corresponding bits in the output enable register
+(BT848_GPIO_OUT_EN) will be set as these pins must be driven by the
+bt848 chip.
+
+The audiomux[] array holds the data values for the different inputs
+(i.e. which pins must be high/low for tuner/mute/...).  This will be
+written to the data register (BT848_GPIO_DATA) to switch the audio
+mux.
+
+
+What you have to do is figure out the correct values for gpiomask and
+the audiomux array.  If you have Windows and the drivers four your
+card installed, you might to check out if you can read these registers
+values used by the windows driver.  A tool to do this is available
+from ftp://telepresence.dmem.strath.ac.uk/pub/bt848/winutil, but it
+does'nt work with bt878 boards according to some reports I received.
+Another one with bt878 suport is available from
+http://btwincap.sourceforge.net/Files/btspy2.00.zip
+
+You might also dig around in the *.ini files of the Windows applications.
+You can have a look at the board to see which of the gpio pins are
+connected at all and then start trial-and-error ...
+
+
+Starting with release 0.7.41 bttv has a number of insmod options to
+make the gpio debugging easier:
+
+bttv_gpio=0/1		enable/disable gpio debug messages
+gpiomask=n		set the gpiomask value
+audiomux=i,j,...	set the values of the audiomux array
+audioall=a		set the values of the audiomux array (one
+			value for all array elements, useful to check
+			out which effect the particular value has).
+
+The messages printed with bttv_gpio=1 look like this:
+
+	bttv0: gpio: en=00000027, out=00000024 in=00ffffd8 [audio: off]
+
+en  =	output _en_able register (BT848_GPIO_OUT_EN)
+out =	_out_put bits of the data register (BT848_GPIO_DATA),
+	i.e. BT848_GPIO_DATA & BT848_GPIO_OUT_EN
+in  = 	_in_put bits of the data register,
+	i.e. BT848_GPIO_DATA & ~BT848_GPIO_OUT_EN
+
+
+
+Other elements of the tvcards array
+===================================
+
+If you are trying to make a new card work you might find it useful to
+know what the other elements in the tvcards array are good for:
+
+video_inputs    - # of video inputs the card has
+audio_inputs    - historical cruft, not used any more.
+tuner           - which input is the tuner
+svhs            - which input is svhs (all others are labeled composite)
+muxsel          - video mux, input->registervalue mapping
+pll             - same as pll= insmod option
+tuner_type      - same as tuner= insmod option
+*_modulename    - hint whenever some card needs this or that audio
+                  module loaded to work properly.
+has_radio	- whenever this TV card has a radio tuner.
+no_msp34xx	- "1" disables loading of msp3400.o module
+no_tda9875	- "1" disables loading of tda9875.o module 
+needs_tvaudio	- set to "1" to load tvaudio.o module 
+
+If some config item is specified both from the tvcards array and as
+insmod option, the insmod option takes precedence.
+
+
+
+Good luck,
+
+  Gerd

+    i2c-addresses: 0x88 or 0x8a

+  via a 9 pin connector ( 4-wire SDATA, 2-wire i2c, SCLK, VCC, GND).
+  It outputs an 8-bit 4:2:2 YUV or YCrCb video signal which can be directly
+  connected to bt848/bt878 GPIO pins on this purpose.
+  (see: VLSI Vision Ltd. www.vvl.co.uk for camera datasheets)
+  
+  Supported Cards:
+  -  Pixelview Rev.4E: 0x8a
+		GPIO 0x400000 toggles Bt832 RESET, and the chip changes to i2c 0x88 !
+
+  (c) Gunther Mayer, 2002

+  - detect chip and hexdump
+  - reset chip and leave low power mode
+  - detect camera present

+ Video Sampling
+Digital video is a sampled form of analog video. The most common sampling schemes in use today are:
+                  Pixel Clock   Horiz    Horiz    Vert
+                   Rate         Total    Active
+NTSC square pixel  12.27 MHz    780      640      525
+NTSC CCIR-601      13.5  MHz    858      720      525
+NTSC 4FSc          14.32 MHz    910      768      525
+PAL  square pixel  14.75 MHz    944      768      625
+PAL  CCIR-601      13.5  MHz    864      720      625
+PAL  4FSc          17.72 MHz   1135      948      625
+
+For the CCIR-601 standards, the sampling is based on a static orthogonal sampling grid. The luminance component (Y) is sampled at 13.5 MHz, while the two color difference signals, Cr and Cb are sampled at half that, or 6.75 MHz. The Cr and Cb samples are colocated with alternate Y samples, and they are taken at the same position on each line, such that one sample is coincident with the 50% point of the falling edge of analog sync. The samples are coded to either 8 or 10 bits per component.

+ * connection prior to establish a new one, pulsing the STROBE pin.
+ *
+ * The board hardwire Y0 (xpoint) to MUX1 and MUXOUT to Yin.
+ * GPIO pins are wired as:
+ *  GPIO[0:3] - AX[0:3] (xpoint) - P1[0:3] (microcontroler)
+ *  GPIO[4:6] - AY[0:2] (xpoint) - P1[4:6] (microcontroler)
+ *  GPIO[7]   - DATA (xpoint)    - P1[7] (microcontroler)
+ *  GPIO[8]   -                  - P3[5] (microcontroler)
+ *  GPIO[9]   - RESET (xpoint)   - P3[6] (microcontroler)
+ *  GPIO[10]  - STROBE (xpoint)  - P3[7] (microcontroler)
+ *  GPINTR    -                  - P3[4] (microcontroler)
+ *
+ * The microcontroler is a 80C32 like. It should be possible to change xpoint
+ * configuration either directly (as we are doing) or using the microcontroler
+ * which is also wired to I2C interface. I have no further info on the
+ * microcontroler features, one would need to disassembly the firmware.

+
+    -----------------------------------------------------------------------
+
+    Lot of voodoo here.  Even the data sheet doesn't help to
+    understand what is going on here, the documentation for the audio
+    part of the cx2388x chip is *very* bad.
+
+    Some of this comes from party done linux driver sources I got from
+    [undocumented].
+
+    Some comes from the dscaler sources, the dscaler driver guy works
+    for Conexant ...

+ *  AM-Mono
+ *      Support for Hauppauge cards added (decoding handled by tuner) added by

+ *
+ *  FM-Mono
+ *      should work. The stereo modes are backward compatible to FM-mono,
+ *      therefore FM-Mono should be allways available.
+ *
+ *  FM-Stereo (B/G, used in germany)
+ *      should work, with autodetect
+ *
+ *  FM-Stereo (satellite)
+ *      should work, no autodetect (i.e. default is mono, but you can
+ *      switch to stereo -- untested)
+ *
+ *  NICAM (B/G, L , used in UK, Scandinavia, Spain and France)
+ *      should work, with autodetect. Support for NICAM was added by
+ *      Pekka Pietikainen <pp@netppl.fi>

+ *
+ * what works and what doesn't:
+ *
+ *  AM-Mono
+ *      Support for Hauppauge cards added (decoding handled by tuner) added by
+ *      Frederic Crozat <fcrozat@mail.dotcom.fr>
+ *
+ *  FM-Mono
+ *      should work. The stereo modes are backward compatible to FM-mono,
+ *      therefore FM-Mono should be allways available.
+ *
+ *  FM-Stereo (B/G, used in germany)
+ *      should work, with autodetect
+ *
+ *  FM-Stereo (satellite)
+ *      should work, no autodetect (i.e. default is mono, but you can
+ *      switch to stereo -- untested)
+ *
+ *  NICAM (B/G, L , used in UK, Scandinavia, Spain and France)
+ *      should work, with autodetect. Support for NICAM was added by
+ *      Pekka Pietikainen <pp@netppl.fi>

+ * generic helper functions for video4linux capture buffers, to handle
+ * memory management and PCI DMA.  Right now bttv + saa7134 use it.
+ *
+ * The functions expect the hardware being able to scatter gatter
+ * (i.e. the buffers are not linear in physical memory, but fragmented
+ * into PAGE_SIZE chunks).  They also assume the driver does not need
+ * to touch the video data (thus it is probably not useful for USB as
+ * data often must be uncompressed by the drivers).
