10 I2C (pronounce: I-square-C) is a slow serial bus protocol used in
11 many micro controller applications and developed by Philips. SMBus,
12 or System Management Bus is a subset of the I2C protocol. More
13 information is contained in the directory <file:Documentation/i2c/>,
14 especially in the file called "summary" there.
15
16 Both I2C and SMBus are supported here. You will need this for
17 hardware sensors support, and also for Video For Linux support.
18
19 If you want I2C support, you should say Y here and also to the
20 specific driver for your bus adapter(s) below.
21
22 This I2C support can also be built as a module. If so, the module
23 will be called i2c-core.

28 help
29 Say Y here to use i2c-* device files, usually found in the /dev
30 directory on your system. They make it possible to have user-space
31 programs use the I2C bus. Information on how to do this is
32 contained in the file <file:Documentation/i2c/dev-interface>.
33
34 This support is also available as a module. If so, the module
35 will be called i2c-dev.

45 Say Y here if you want the I2C core to produce a bunch of debug
46 messages to the system log. Select this if you are having a
47 problem with I2C support and want to see more of what is going on.
