11Description
12-----------
13
14The Savage4 chips contain two I2C interfaces (aka a I2C 'master'
15or 'host').
16
17The first interface is used for DDC (Data Display Channel) which is a
18serial channel through the VGA monitor connector to a DDC-compliant
19monitor. This interface is defined by the Video Electronics Standards
20Association (VESA). The standards are available for purchase at
21http://www.vesa.org . The DDC bus is not yet supported because its register
22is not directly memory-mapped.
23
24The second interface is a general-purpose I2C bus. This is the only
25interface supported by the driver at the moment.
