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!

Kernel driver i2c-savage4
Supported adapters:
* Savage4
* Savage2000
Authors:

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.
