Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!

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.
