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
-----------
i2c-via is an i2c bus driver for motherboards with VIA chipset.
The following VIA pci chipsets are supported:
- MVP3, VP3, VP2/97, VPX/97
- others with South bridge VT82C586B
Your lspci listing must show this :
Bridge: VIA Technologies, Inc. VT82C586B ACPI (rev 10)
Problems?
Q: You have VT82C586B on the motherboard, but not in the listing.
A: Go to your BIOS setup, section PCI devices or similar.
Turn USB support on, and try again.
Q: No error messages, but still i2c doesn't seem to work.
A: This can happen. This driver uses the pins VIA recommends in their
datasheets, but there are several ways the motherboard manufacturer
can actually wire the lines.
