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!

---help---
|
|
I2C (pronounce: I-square-C) is a slow serial bus protocol used in
|
|
many micro controller applications and developed by Philips. SMBus,
|
|
or System Management Bus is a subset of the I2C protocol. More
|
|
information is contained in the directory <file:Documentation/i2c/>,
|
|
especially in the file called "summary" there.
|
|
|
|
Both I2C and SMBus are supported here. You will need this for
|
|
hardware sensors support, and also for Video For Linux support.
|
|
|
|
If you want I2C support, you should say Y here and also to the
|
|
specific driver for your bus adapter(s) below.
|
|
|
|
This I2C support can also be built as a module. If so, the module
|
|
will be called i2c-core.

help
|
|
Say Y here to use i2c-* device files, usually found in the /dev
|
|
directory on your system. They make it possible to have user-space
|
|
programs use the I2C bus. Information on how to do this is
|
|
contained in the file <file:Documentation/i2c/dev-interface>.
|
|
|
|
This support is also available as a module. If so, the module
|
|
will be called i2c-dev.
