6 tristate "I2C support"
10 I2C (pronounce: I-squared-C) is a slow serial bus protocol used in
12 or System Management Bus is a subset of the I2C protocol. More
13 information is contained in the directory <file:Documentation/i2c/>,
16 Both I2C and SMBus are supported here. You will need this for
19 If you want I2C support, you should say Y here and also to the
22 This I2C support can also be built as a module. If so, the module
23 will be called i2c-core.

40 tristate "I2C device interface"
42 Say Y here to use i2c-* device files, usually found in the /dev
44 programs use the I2C bus. Information on how to do this is
45 contained in the file <file:Documentation/i2c/dev-interface>.
48 will be called i2c-dev.
51 tristate "I2C bus multiplexing support"
54 Say Y here if you want the I2C core to support the ability to
55 handle multiplexed I2C bus topologies, by presenting each
56 multiplexed segment as a I2C adapter.
59 will be called i2c-mux.
61 source drivers/i2c/muxes/Kconfig
67 Some I2C bus drivers require so-called "I2C algorithm" modules
69 I2C interfaces. This option will autoselect them so that you don't
73 modules, for example for use with external I2C bus drivers.
80 Say Y here if you want support for SMBus extensions to the I2C
85 will be called i2c-smbus.
