! 525: * GPIO pins (eg radio chips or MSP34xx reset logic)
! 526: *

! 530: *
! 531: * The current probe code works as follows

! 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
