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.
