524 * determine the card brand/model
525 * BKTR_OVERRIDE_CARD, BKTR_OVERRIDE_TUNER, BKTR_OVERRIDE_DBX and
526 * BKTR_OVERRIDE_MSP can be used to select a specific device,
527 * regardless of the autodetection and i2c device checks.
528 *
529 * The scheme used for probing cards faces these problems:
530 * It is impossible to work out which type of tuner is actually fitted,
531 * (the driver cannot tell if the Tuner is PAL or NTSC, Temic or Philips)
532 * It is impossible to determine what audio-mux hardware is connected.
533 * It is impossible to determine if there is extra hardware connected to the
534 * GPIO pins (eg radio chips or MSP34xx reset logic)
535 *
536 * However some makes of card (eg Hauppauge) come with a configuration eeprom
537 * which tells us the make of the card. Most eeproms also tell us the
538 * tuner type and other features of the the cards.
539 *
540 * The current probe code works as follows
541 * A) If the card uses a Bt878/879:
542 * 1) Read the sub-system vendor id from the configuration EEPROM.
543 * Select the required tuner, audio mux arrangement and any other
544 * onboard features. If this fails, move to step B.
545 * B) If it card uses a Bt848, 848A, 849A or an unknown Bt878/879:
546 * 1) Look for I2C devices. If there are none fitted, it is an Intel or
547 * VideoLogic cards.
548 * 2) Look for a configuration EEPROM.
549 * 2a) If there is one at I2C address 0xa0 it may be
550 * a Hauppauge or an Osprey. Check the EEPROM contents to determine which
551 * one it is. For Hauppauge, select the tuner type and audio hardware.
552 * 2b) If there is an EEPROM at I2C address 0xa8 it will be an STB card.
553 * We still have to guess on the tuner type.
554 *
555 * C) If we do not know the card type from (A) or (B), guess at the tuner
556 * type based on the I2C address of the tuner.
557 *
558 * D) After determining the Tuner Type, we probe the i2c bus for other
559 * devices at known locations, eg IR-Remote Control, MSP34xx and TDA
560 * stereo chips.

530 * It is impossible to work out which type of tuner is actually fitted,
531 * (the driver cannot tell if the Tuner is PAL or NTSC, Temic or Philips)
532 * It is impossible to determine what audio-mux hardware is connected.
533 * It is impossible to determine if there is extra hardware connected to the
534 * GPIO pins (eg radio chips or MSP34xx reset logic)
535 *
536 * However some makes of card (eg Hauppauge) come with a configuration eeprom
537 * which tells us the make of the card. Most eeproms also tell us the
538 * tuner type and other features of the the cards.
539 *
540 * The current probe code works as follows
541 * A) If the card uses a Bt878/879:
542 * 1) Read the sub-system vendor id from the configuration EEPROM.
543 * Select the required tuner, audio mux arrangement and any other
544 * onboard features. If this fails, move to step B.
545 * B) If it card uses a Bt848, 848A, 849A or an unknown Bt878/879:
546 * 1) Look for I2C devices. If there are none fitted, it is an Intel or
547 * VideoLogic cards.
548 * 2) Look for a configuration EEPROM.
549 * 2a) If there is one at I2C address 0xa0 it may be
550 * a Hauppauge or an Osprey. Check the EEPROM contents to determine which
551 * one it is. For Hauppauge, select the tuner type and audio hardware.
552 * 2b) If there is an EEPROM at I2C address 0xa8 it will be an STB card.
553 * We still have to guess on the tuner type.
554 *
555 * C) If we do not know the card type from (A) or (B), guess at the tuner
556 * type based on the I2C address of the tuner.
557 *
558 * D) After determining the Tuner Type, we probe the i2c bus for other
559 * devices at known locations, eg IR-Remote Control, MSP34xx and TDA
560 * stereo chips.
