525: * GPIO pins (eg radio chips or MSP34xx reset logic)
526: *
527: * However some makes of card (eg Hauppauge) come with a configuration eeprom
528: * which tells us the make of the card. Most eeproms also tell us the
529: * tuner type and other features of the cards.
530: *
531: * The current probe code works as follows
532: * A) If the card uses a Bt878/879:
533: * 1) Read the sub-system vendor id from the configuration EEPROM.
534: * Select the required tuner, audio mux arrangement and any other
535: * onboard features. If this fails, move to step B.
536: * B) If it card uses a Bt848, 848A, 849A or an unknown Bt878/879:
537: * 1) Look for I2C devices. If there are none fitted, it is an Intel or
538: * VideoLogic cards.
539: * 2) Look for a configuration EEPROM.
540: * 2a) If there is one at I2C address 0xa0 it may be
541: * a Hauppauge or an Osprey. Check the EEPROM contents to determine which
542: * one it is. For Hauppauge, select the tuner type and audio hardware.
543: * 2b) If there is an EEPROM at I2C address 0xa8 it will be an STB card.
544: * We still have to guess on the tuner type.
545: *
546: * C) If we do not know the card type from (A) or (B), guess at the tuner
547: * type based on the I2C address of the tuner.
548: *
549: * D) After determining the Tuner Type, we probe the i2c bus for other
550: * devices at known locations, eg IR-Remote Control, MSP34xx and TDA
551: * stereo chips.
