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!

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==============

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.

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)
