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