  518  * regardless of the autodetection and i2c device checks.
  519  *
  520  * The scheme used for probing cards faces these problems:
  521  *  It is impossible to work out which type of tuner is actually fitted,
  522  *  (the driver cannot tell if the Tuner is PAL or NTSC, Temic or Philips)
  523  *  It is impossible to determine what audio-mux hardware is connected.
  524  *  It is impossible to determine if there is extra hardware connected to the
  525  *  GPIO pins  (eg radio chips or MSP34xx reset logic)
  526  *
  527  * However some makes of card (eg Hauppauge) come with a configuration eeprom
  528  * which tells us the make of the card. Most eeproms also tell us the
  529  * tuner type and other features of the cards.
  530  *
  531  * The current probe code works as follows
  532  * A) If the card uses a Bt878/879:
  533  *   1) Read the sub-system vendor id from the configuration EEPROM.
  534  *      Select the required tuner, audio mux arrangement and any other
  535  *      onboard features. If this fails, move to step B.
  536  * B) If it card uses a Bt848, 848A, 849A or an unknown Bt878/879:
  537  *   1) Look for I2C devices. If there are none fitted, it is an Intel or
  538  *      VideoLogic cards.
  539  *   2) Look for a configuration EEPROM.
  540  *   2a) If there is one at I2C address 0xa0 it may be
  541  *       a Hauppauge or an Osprey. Check the EEPROM contents to determine which
  542  *       one it is. For Hauppauge, select the tuner type and audio hardware.
  543  *   2b) If there is an EEPROM at I2C address 0xa8 it will be an STB card.
  544  *       We still have to guess on the tuner type.
  545  *
  546  * C) If we do not know the card type from (A) or (B), guess at the tuner
  547  *    type based on the I2C address of the tuner.
  548  *
  549  * D) After determining the Tuner Type, we probe the i2c bus for other
  550  *    devices at known locations, eg IR-Remote Control, MSP34xx and TDA
  551  *    stereo chips.
