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