6	==========================================================================
7	
8	bttv.o
9		the bt848/878 (grabber chip) driver
10	
11		insmod args:
12			card=n		card type, see CARDLIST for a list.
13			tuner=n		tuner type, see CARDLIST for a list.
14			radio=0/1	card supports radio
15			pll=0/1/2	pll settings
16				0: don't use PLL
17				1: 28 MHz crystal installed
18				2: 35 MHz crystal installed
19	
20			triton1=0/1     for Triton1 (+others) compatibility
21			vsfx=0/1	yet another chipset bug compatibility bit
22					see README.quirks for details on these two.
23	
24			bigendian=n	Set the endianness of the gfx framebuffer.
25					Default is native endian.
26			fieldnr=0/1	Count fields.  Some TV descrambling software
27					needs this, for others it only generates
28					50 useless IRQs/sec.  default is 0 (off).
29			autoload=0/1	autoload helper modules (tuner, audio).
30					default is 1 (on).
31			bttv_verbose=0/1/2  verbose level (at insmod time, while
32					looking at the hardware).  default is 1.
33			bttv_debug=0/1	debug messages (for capture).
34					default is 0 (off).
35			irq_debug=0/1	irq handler debug messages.
36					default is 0 (off).
37			gbuffers=2-32	number of capture buffers for mmap'ed capture.
38					default is 4.
39			gbufsize=	size of capture buffers. default and
40					maximum value is 0x208000 (~2MB)
41			no_overlay=0	Enable overlay on broken hardware.  There
42					are some chipsets (SIS for example) which
43					are known to have problems with the PCI DMA
44					push used by bttv.  bttv will disable overlay
45					by default on this hardware to avoid crashes.
46					With this insmod option you can override this.
47			no_overlay=1	Disable overlay. It should be used by broken
48					hardware that doesn't support PCI2PCI direct
49					transfers.
50			automute=0/1	Automatically mutes the sound if there is
51					no TV signal, on by default.  You might try
52					to disable this if you have bad input signal
53					quality which leading to unwanted sound
54					dropouts.
55			chroma_agc=0/1	AGC of chroma signal, off by default.
56			adc_crush=0/1	Luminance ADC crush, on by default.
57			i2c_udelay=     Allow reduce I2C speed. Default is 5 usecs
58					(meaning 66,67 Kbps). The default is the
59					maximum supported speed by kernel bitbang
60					algorithm. You may use lower numbers, if I2C
61					messages are lost (16 is known to work on
62					all supported cards).
63	
64			bttv_gpio=0/1
65			gpiomask=
66			audioall=
67			audiomux=
68					See Sound-FAQ for a detailed description.
69	
70		remap, card, radio and pll accept up to four comma-separated arguments
71		(for multiple boards).
72	
73	tuner.o
74		The tuner driver.  You need this unless you want to use only
75		with a camera or external tuner ...
76	
77		insmod args:
78			debug=1		print some debug info to the syslog
79			type=n		type of the tuner chip. n as follows:
80					see CARDLIST for a complete list.
81			pal=[bdgil]	select PAL variant (used for some tuners
82					only, important for the audio carrier).
83	
84	tvaudio.o
85		new, experimental module which is supported to provide a single
86		driver for all simple i2c audio control chips (tda/tea*).
87	
88		insmod args:
89			tda8425  = 1	enable/disable the support for the
90			tda9840  = 1	various chips.
91			tda9850  = 1	The tea6300 can't be autodetected and is
92			tda9855  = 1	therefore off by default, if you have
93			tda9873  = 1	this one on your card (STB uses these)
94			tda9874a = 1	you have to enable it explicitly.
95			tea6300  = 0	The two tda985x chips use the same i2c
96			tea6420  = 1	address and can't be disturgished from
97			pic16c54 = 1	each other, you might have to disable
98					the wrong one.
99			debug = 1	print debug messages
100	
101		insmod args for tda9874a:
102			tda9874a_SIF=1/2	select sound IF input pin (1 or 2)
103						(default is pin 1)
104			tda9874a_AMSEL=0/1	auto-mute select for NICAM (default=0)
105						Please read note 3 below!
106			tda9874a_STD=n		select TV sound standard (0..8):
107						0 - A2, B/G
108						1 - A2, M (Korea)
109						2 - A2, D/K (1)
110						3 - A2, D/K (2)
111						4 - A2, D/K (3)
112						5 - NICAM, I
113						6 - NICAM, B/G
114						7 - NICAM, D/K (default)
115						8 - NICAM, L
116	
117		Note 1: tda9874a supports both tda9874h (old) and tda9874a (new) chips.
118		Note 2: tda9874h/a and tda9875 (which is supported separately by
119		tda9875.o) use the same i2c address so both modules should not be
120		used at the same time.
121		Note 3: Using tda9874a_AMSEL option depends on your TV card design!
122			AMSEL=0: auto-mute will switch between NICAM sound
123				 and the sound on 1st carrier (i.e. FM mono or AM).
124			AMSEL=1: auto-mute will switch between NICAM sound
125				 and the analog mono input (MONOIN pin).
126		If tda9874a decoder on your card has MONOIN pin not connected, then
127		use only tda9874_AMSEL=0 or don't specify this option at all.
128		For example:
129		  card=65 (FlyVideo 2000S) - set AMSEL=1 or AMSEL=0
130		  card=72 (Prolink PV-BT878P rev.9B) - set AMSEL=0 only
131	
132	msp3400.o
133		The driver for the msp34xx sound processor chips. If you have a
134		stereo card, you probably want to insmod this one.
135	
136		insmod args:
137			debug=1/2	print some debug info to the syslog,
138					2 is more verbose.
139			simple=1	Use the "short programming" method.  Newer
140					msp34xx versions support this.  You need this
141					for dbx stereo.  Default is on if supported by
142					the chip.
143			once=1		Don't check the TV-stations Audio mode
144					every few seconds, but only once after
145					channel switches.
146			amsound=1	Audio carrier is AM/NICAM at 6.5 Mhz.  This
147					should improve things for french people, the
148					carrier autoscan seems to work with FM only...
149	
150	tea6300.o - OBSOLETE (use tvaudio instead)
151		The driver for the tea6300 fader chip.  If you have a stereo
152		card and the msp3400.o doesn't work, you might want to try this
153		one.  This chip is seen on most STB TV/FM cards (usually from
154		Gateway OEM sold surplus on auction sites).
155	
156		insmod args:
157			debug=1		print some debug info to the syslog.
158	
159	tda8425.o - OBSOLETE (use tvaudio instead)
160		The driver for the tda8425 fader chip.  This driver used to be
161		part of bttv.c, so if your sound used to work but does not
162		anymore, try loading this module.
163	
164		insmod args:
165			debug=1		print some debug info to the syslog.
166	
167	tda985x.o - OBSOLETE (use tvaudio instead)
168		The driver for the tda9850/55 audio chips.
169	
170		insmod args:
171			debug=1		print some debug info to the syslog.
172			chip=9850/9855	set the chip type.
