   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
   8description.

  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.

  40Please mail me unified diffs ("diff -u") with your changes, and don't
  41forget to tell me what it changes / which problem it fixes / whatever
  42it is good for ...

  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.
