561 * BKTR_OVERRIDE_MSP can be used to select a specific device,
562 * regardless of the autodetection and i2c device checks.
563 *
564 * The scheme used for probing cards faces these problems:
565 * It is impossible to work out which type of tuner is actually fitted,
566 * (the driver cannot tell if the Tuner is PAL or NTSC, Temic or Philips)
567 * It is impossible to determine what audio-mux hardware is connected.
568 * It is impossible to determine if there is extra hardware connected to the
569 * GPIO pins (eg radio chips or MSP34xx reset logic)
570 *
571 * However some makes of card (eg Hauppauge) come with a configuration eeprom
572 * which tells us the make of the card. Most eeproms also tell us the
573 * tuner type and other features of the cards.
574 *
575 * The current probe code works as follows
576 * A) If the card uses a Bt878/879:
577 * 1) Read the sub-system vendor id from the configuration EEPROM.
578 * Select the required tuner, audio mux arrangement and any other
579 * onboard features. If this fails, move to step B.
580 * B) If it card uses a Bt848, 848A, 849A or an unknown Bt878/879:
581 * 1) Look for I2C devices. If there are none fitted, it is an Intel or
582 * VideoLogic cards.
583 * 2) Look for a configuration EEPROM.
584 * 2a) If there is one at I2C address 0xa0 it may be
585 * a Hauppauge or an Osprey. Check the EEPROM contents to determine which
586 * one it is. For Hauppauge, select the tuner type and audio hardware.
587 * 2b) If there is an EEPROM at I2C address 0xa8 it will be an STB card.
588 * We still have to guess on the tuner type.
589 *
590 * C) If we do not know the card type from (A) or (B), guess at the tuner
591 * type based on the I2C address of the tuner.
592 *
593 * D) After determining the Tuner Type, we probe the i2c bus for other
594 * devices at known locations, eg IR-Remote Control, MSP34xx and TDA
595 * stereo chips.
