 7config I2C
 8	tristate "I2C support"
 9	---help---
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.
24
25config I2C_CHARDEV
26	tristate "I2C device interface"
27	depends on I2C
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.
