Description
|
||
|
|
-----------
|
||
|
|
|
||
|
|
The Savage4 chips contain 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 DDC bus is not yet supported because its register
|
||
|
|
is not directly memory-mapped.
|
||
|
|
|
||
|
|
The second interface is a general-purpose I2C bus. This is the only
|
||
|
|
interface supported by the driver at the moment.
