| 530 | * |
| 531 | * The scheme used for probing cards faces these problems: |
| 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. |
