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