509  *
510  * The scheme used for probing cards faces these problems:
511  *  It is impossible to work out which type of tuner is actually fitted,
512  *  (the driver cannot tell if the Tuner is PAL or NTSC, Temic or Philips)
513  *  It is impossible to determine what audio-mux hardware is connected.
514  *  It is impossible to determine if there is extra hardware connected to the
515  *  GPIO pins  (eg radio chips or MSP34xx reset logic)
516  *
517  * However some makes of card (eg Hauppauge) come with a configuration eeprom
518  * which tells us the make of the card. Most eeproms also tell us the
519  * tuner type and other features of the cards.
520  *
521  * The current probe code works as follows
522  * A) If the card uses a Bt878/879:
523  *   1) Read the sub-system vendor id from the configuration EEPROM.
524  *      Select the required tuner, audio mux arrangement and any other
525  *      onboard features. If this fails, move to step B.
526  * B) If it card uses a Bt848, 848A, 849A or an unknown Bt878/879:
527  *   1) Look for I2C devices. If there are none fitted, it is an Intel or
528  *      VideoLogic cards.
529  *   2) Look for a configuration EEPROM.
530  *   2a) If there is one at I2C address 0xa0 it may be
531  *       a Hauppauge or an Osprey. Check the EEPROM contents to determine which
532  *       one it is. For Hauppauge, select the tuner type and audio hardware.
533  *   2b) If there is an EEPROM at I2C address 0xa8 it will be an STB card.
534  *       We still have to guess on the tuner type.
535  *
536  * C) If we do not know the card type from (A) or (B), guess at the tuner
537  *    type based on the I2C address of the tuner.
538  *
539  * D) After determining the Tuner Type, we probe the i2c bus for other
540  *    devices at known locations, eg IR-Remote Control, MSP34xx and TDA
541  *    stereo chips.
