494  *
495  * The scheme used for probing cards faces these problems:
496  *  It is impossible to work out which type of tuner is actually fitted,
497  *  (the driver cannot tell if the Tuner is PAL or NTSC, Temic or Philips)
498  *  It is impossible to determine what audio-mux hardware is connected.
499  *  It is impossible to determine if there is extra hardware connected to the
500  *  GPIO pins  (eg radio chips or MSP34xx reset logic)
501  *
502  * However some makes of card (eg Hauppauge) come with a configuration eeprom
503  * which tells us the make of the card. Most eeproms also tell us the
504  * tuner type and other features of the the cards.
505  *
506  * The current probe code works as follows
507  * A) If the card uses a Bt878/879:
508  *   1) Read the sub-system vendor id from the configuration EEPROM.
509  *      Select the required tuner, audio mux arrangement and any other
510  *      onboard features. If this fails, move to step B.
511  * B) If it card uses a Bt848, 848A, 849A or an unknown Bt878/879:
512  *   1) Look for I2C devices. If there are none fitted, it is an Intel or
513  *      VideoLogic cards.
514  *   2) Look for a configuration EEPROM.
515  *   2a) If there is one at I2C address 0xa0 it may be
516  *       a Hauppauge or an Osprey. Check the EEPROM contents to determine which
517  *       one it is. For Hauppauge, select the tuner type and audio hardware.
518  *   2b) If there is an EEPROM at I2C address 0xa8 it will be an STB card.
519  *       We still have to guess on the tuner type.
520  *
521  * C) If we do not know the card type from (A) or (B), guess at the tuner
522  *    type based on the I2C address of the tuner.
523  *
524  * D) After determining the Tuner Type, we probe the i2c bus for other
525  *    devices at known locations, eg IR-Remote Control, MSP34xx and TDA
526  *    stereo chips.
