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