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.
