  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)
  
  Some details about 30/34/35:
  
   - saa7130 - low-price chip, doesn't have mute, that is why all those
   cards should have .mute field defined in their tuner structure.
  
   - saa7134 - usual chip
  
   - saa7133/35 - saa7135 is probably a marketing decision, since all those
   chips identifies itself as 33 on pci.

  Have fun,
