3What is it?
4===========
5
6This is a v4l2/oss device driver for saa7130/33/34/35 based capture / TV
7boards.  See http://www.semiconductors.philips.com/pip/saa7134hl for a

14Almost everything is working.  video, sound, tuner, radio, mpeg ts, ...
15
16As with bttv, card-specific tweaks are needed.  Check CARDLIST for a
17list of known TV cards and saa7134-cards.c for the drivers card
18configuration info.

21Build
22=====
23
24Pick up videodev + v4l2 patches from http://bytesex.org/patches/.
25Configure, build, install + boot the new kernel.  You'll need at least
26these config options:
27
28	CONFIG_I2C=m
29	CONFIG_VIDEO_DEV=m
30
31Type "make" to build the driver now.  "make install" installs the
32driver.  "modprobe saa7134" should load it.  Depending on the card you
33might have to pass card=<nr> as insmod option, check CARDLIST for
34valid choices.

45Known Problems
46==============
47
48* The tuner for the flyvideos isn't detected automatically and the
49  default might not work for you depending on which version you have.
50  There is a tuner= insmod option to override the driver's default.
51
52Card Variations:
53================
54
55Cards can use either of these two crystals (xtal):
56 - 32.11 MHz -> .audio_clock=0x187de7
57 - 24.576MHz -> .audio_clock=0x200000
58(xtal * .audio_clock = 51539600)
59
60Some details about 30/34/35:
61
62 - saa7130 - low-price chip, doesn't have mute, that is why all those
63 cards should have .mute field defined in their tuner structure.
64
65 - saa7134 - usual chip
66
67 - saa7133/35 - saa7135 is probably a marketing decision, since all those
68 chips identifies itself as 33 on pci.
