535 * BKTR_OVERRIDE_MSP can be used to select a specific device,
536 * regardless of the autodetection and i2c device checks.
537 *
538 * The scheme used for probing cards faces these problems:
539 * It is impossible to work out which type of tuner is actually fitted,
540 * (the driver cannot tell if the Tuner is PAL or NTSC, Temic or Philips)
541 * It is impossible to determine what audio-mux hardware is connected.
542 * It is impossible to determine if there is extra hardware connected to the
543 * GPIO pins (eg radio chips or MSP34xx reset logic)
544 *
545 * However some makes of card (eg Hauppauge) come with a configuration eeprom
546 * which tells us the make of the card. Most eeproms also tell us the
547 * tuner type and other features of the cards.
548 *
549 * The current probe code works as follows
550 * A) If the card uses a Bt878/879:
551 * 1) Read the sub-system vendor id from the configuration EEPROM.
552 * Select the required tuner, audio mux arrangement and any other
553 * onboard features. If this fails, move to step B.
554 * B) If it card uses a Bt848, 848A, 849A or an unknown Bt878/879:
555 * 1) Look for I2C devices. If there are none fitted, it is an Intel or
556 * VideoLogic cards.
557 * 2) Look for a configuration EEPROM.
558 * 2a) If there is one at I2C address 0xa0 it may be
559 * a Hauppauge or an Osprey. Check the EEPROM contents to determine which
560 * one it is. For Hauppauge, select the tuner type and audio hardware.
561 * 2b) If there is an EEPROM at I2C address 0xa8 it will be an STB card.
562 * We still have to guess on the tuner type.
563 *
564 * C) If we do not know the card type from (A) or (B), guess at the tuner
565 * type based on the I2C address of the tuner.
566 *
567 * D) After determining the Tuner Type, we probe the i2c bus for other
568 * devices at known locations, eg IR-Remote Control, MSP34xx and TDA
569 * stereo chips.
