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