I2C/DDC support used to live in a separate driver but this caused driver conflicts.

Studebaker - -Main contact: Philip Edelbrock - -The code is based upon Ralph's test code (he did the hard stuff ;') - -Description ------------ - -The 3dfx Voodoo3 chip contains two I2C interfaces (aka a I2C 'master' or -'host'). - -The first interface is used for DDC (Data Display Channel) which is a -serial channel through the VGA monitor connector to a DDC-compliant -monitor. This interface is defined by the Video Electronics Standards -Association (VESA). The standards are available for purchase at -http://www.vesa.org . - -The second interface is a general-purpose I2C bus. The intent by 3dfx was -to allow manufacturers to add extra chips to the video card such as a -TV-out chip such as the BT869 or possibly even I2C based temperature -sensors like the ADM1021 or LM75. - -Stability ---------- - -Seems to be stable on the test machine, but needs more testing on other -machines. Simultaneous accesses of the DDC and I2C busses may cause errors. - -Supported Devices ------------------ - -Specifically, this driver was written and tested on the '3dfx Voodoo3 AGP -3000' which has a tv-out feature (s-video or composite). According to the -docs and discussions, this code should work for any Voodoo3 based cards as -well as Voodoo Banshee based cards. The DDC interface has been tested on a -Voodoo Banshee card. - -Issues ------- - -Probably many, but it seems to work OK on my system. :') - - -External Device Connection --------------------------- - -The digital video input jumpers give availability to the I2C bus. -Specifically, pins 13 and 25 (bottom row middle, and bottom right-end) are -the I2C clock and I2C data lines, respectively. +5V and GND are probably -also easily available making the addition of extra I2C/SMBus devices easy -to implement. -- cgit v1.2.3
