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!

+
+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)
