500 * GPIO pins (eg radio chips or MSP34xx reset logic)
501 *
502 * However some makes of card (eg Hauppauge) come with a configuration eeprom
503 * which tells us the make of the card. Most eeproms also tell us the
504 * tuner type and other features of the the cards.
505 *
506 * The current probe code works as follows
507 * A) If the card uses a Bt878/879:
508 * 1) Read the sub-system vendor id from the configuration EEPROM.
509 * Select the required tuner, audio mux arrangement and any other
510 * onboard features. If this fails, move to step B.
511 * B) If it card uses a Bt848, 848A, 849A or an unknown Bt878/879:
512 * 1) Look for I2C devices. If there are none fitted, it is an Intel or
513 * VideoLogic cards.
514 * 2) Look for a configuration EEPROM.
515 * 2a) If there is one at I2C address 0xa0 it may be
516 * a Hauppauge or an Osprey. Check the EEPROM contents to determine which
517 * one it is. For Hauppauge, select the tuner type and audio hardware.
518 * 2b) If there is an EEPROM at I2C address 0xa8 it will be an STB card.
519 * We still have to guess on the tuner type.
520 *
521 * C) If we do not know the card type from (A) or (B), guess at the tuner
522 * type based on the I2C address of the tuner.
523 *
524 * D) After determining the Tuner Type, we probe the i2c bus for other
525 * devices at known locations, eg IR-Remote Control, MSP34xx and TDA
526 * stereo chips.
