489 * regardless of the autodetection and i2c device checks.
490 *
491 * The scheme used for probing cards faces these problems:
492 *  It is impossible to work out which type of tuner is actually fitted,
493 *  (the driver cannot tell if the Tuner is PAL or NTSC, Temic or Philips)
494 *  It is impossible to determine what audio-mux hardware is connected.
495 *  It is impossible to determine if there is extra hardware connected to the
496 *  GPIO pins  (eg radio chips or MSP34xx reset logic)
497 *
498 * However some makes of card (eg Hauppauge) come with a configuration eeprom
499 * which tells us the make of the card. Most eeproms also tell us the
500 * tuner type and other features of the the cards.
501 *
502 * The current probe code works as follows
503 * A) If the card uses a Bt878/879:
504 *   1) Read the sub-system vendor id from the configuration EEPROM.
505 *      Select the required tuner, audio mux arrangement and any other
506 *      onboard features. If this fails, move to step B.
507 * B) If it card uses a Bt848, 848A, 849A or an unknown Bt878/879:
508 *   1) Look for I2C devices. If there are none fitted, it is an Intel or
509 *      VideoLogic cards.
510 *   2) Look for a configuration EEPROM.
511 *   2a) If there is one at I2C address 0xa0 it may be
512 *       a Hauppauge or an Osprey. Check the EEPROM contents to determine which
513 *       one it is. For Hauppauge, select the tuner type and audio hardware.
514 *   2b) If there is an EEPROM at I2C address 0xa8 it will be an STB card.
515 *       We still have to guess on the tuner type.
516 *
517 * C) If we do not know the card type from (A) or (B), guess at the tuner
518 *    type based on the I2C address of the tuner.
519 *
520 * D) After determining the Tuner Type, we probe the i2c bus for other
521 *    devices at known locations, eg IR-Remote Control, MSP34xx and TDA
522 *    stereo chips.
