   7 This is a v4l2/oss device driver for saa7130/33/34/35 based capture / TV
   8 boards.  See http://www.semiconductors.philips.com/pip/saa7134hl for a
   9 description.

  15 Almost everything is working.  video, sound, tuner, radio, mpeg ts, ...

  17 As with bttv, card-specific tweaks are needed.  Check CARDLIST for a
  18 list of known TV cards and saa7134-cards.c for the drivers card
  19 configuration info.

  25 Pick up videodev + v4l2 patches from http://bytesex.org/patches/.
  26 Configure, build, install + boot the new kernel.  You'll need at least
  27 these config options:
  28
  29 .. code-block:: none
  30
  31         CONFIG_I2C=m
  32         CONFIG_VIDEO_DEV=m
  33
  34 Type "make" to build the driver now.  "make install" installs the
  35 driver.  "modprobe saa7134" should load it.  Depending on the card you
  36 might have to pass card=<nr> as insmod option, check CARDLIST for
  37 valid choices.

  48 Known Problems
  49 --------------
  50
  51 * The tuner for the flyvideos isn't detected automatically and the
  52   default might not work for you depending on which version you have.
  53   There is a tuner= insmod option to override the driver's default.
  54
  55 Card Variations:
  56 ----------------
  57
  58 Cards can use either of these two crystals (xtal):
  59
  60 - 32.11 MHz -> .audio_clock=0x187de7
  61 - 24.576MHz -> .audio_clock=0x200000 (xtal * .audio_clock = 51539600)
  62
  63 Some details about 30/34/35:
  64
  65 - saa7130 - low-price chip, doesn't have mute, that is why all those
  66   cards should have .mute field defined in their tuner structure.
  67
  68 - saa7134 - usual chip
  69
  70 - saa7133/35 - saa7135 is probably a marketing decision, since all those
  71   chips identifies itself as 33 on pci.
