488 * BKTR_OVERRIDE_MSP can be used to select a specific device,
489 * regardless of the autodetection and i2c device checks.
491 * The scheme used for probing cards faces these problems:
492 * It is impossible to work out which type of tuner is actually fitted,
493 * (the driver cannot tell if the Tuner is PAL or NTSC, Temic or Philips)
494 * It is impossible to determine what audio-mux hardware is connected.
495 * It is impossible to determine if there is extra hardware connected to the
496 * GPIO pins (eg radio chips or MSP34xx reset logic)
498 * However some makes of card (eg Hauppauge) come with a configuration eeprom
499 * which tells us the make of the card. Most eeproms also tell us the
500 * tuner type and other features of the the cards.
502 * The current probe code works as follows
503 * A) If the card uses a Bt878/879:
504 * 1) Read the sub-system vendor id from the configuration EEPROM.
505 * Select the required tuner, audio mux arrangement and any other
506 * onboard features. If this fails, move to step B.
507 * B) If it card uses a Bt848, 848A, 849A or an unknown Bt878/879:
508 * 1) Look for I2C devices. If there are none fitted, it is an Intel or
510 * 2) Look for a configuration EEPROM.
511 * 2a) If there is one at I2C address 0xa0 it may be
512 * a Hauppauge or an Osprey. Check the EEPROM contents to determine which
513 * one it is. For Hauppauge, select the tuner type and audio hardware.
514 * 2b) If there is an EEPROM at I2C address 0xa8 it will be an STB card.
515 * We still have to guess on the tuner type.
517 * C) If we do not know the card type from (A) or (B), guess at the tuner
518 * type based on the I2C address of the tuner.
520 * D) After determining the Tuner Type, we probe the i2c bus for other
521 * devices at known locations, eg IR-Remote Control, MSP34xx and TDA
527 * These are the sub-system vendor ID codes stored in the
528 * configuration EEPROM used on Bt878/879 cards. They should match the
529 * number assigned to the company by the PCI Special Interest Group
