|
* BKTR_OVERRIDE_MSP can be used to select a specific device,
|
|
* regardless of the autodetection and i2c device checks.
|
|
*
|
|
* 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.
