16Description 
17----------- 
18
19WARNING: If you have an '810' or '815' motherboard, your standard I2C
20temperature sensors are most likely on the 801's I2C bus. You want the
21i2c-i801 driver for those, not this driver.
22
23Now for the i2c-i810...
24
25The GMCH chip contains two I2C interfaces.
26
27The first interface is used for DDC (Data Display Channel) which is a
28serial channel through the VGA monitor connector to a DDC-compliant
29monitor. This interface is defined by the Video Electronics Standards
30Association (VESA). The standards are available for purchase at
31http://www.vesa.org .
32
33The second interface is a general-purpose I2C bus. It may be connected to a
34TV-out chip such as the BT869 or possibly to a digital flat-panel display.

36Features
37-------- 
38
39Both busses use the i2c-algo-bit driver for 'bit banging'
40and support for specific transactions is provided by i2c-algo-bit.

42Issues
43------
44
45If you enable bus testing in i2c-algo-bit (insmod i2c-algo-bit bit_test=1),
46the test may fail; if so, the i2c-i810 driver won't be inserted. However,
47we think this has been fixed.
