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.
16 Both I2C and SMBus are supported here. You will need this for
17 hardware sensors support, and also for Video For Linux support.
19 If you want I2C support, you should say Y here and also to the
20 specific driver for your bus adapter(s) below.
22 This I2C support can also be built as a module. If so, the module
23 will be called i2c-core.
32 tristate "I2C device interface"
34 Say Y here to use i2c-* device files, usually found in the /dev
35 directory on your system. They make it possible to have user-space
36 programs use the I2C bus. Information on how to do this is
37 contained in the file <file:Documentation/i2c/dev-interface>.
39 This support is also available as a module. If so, the module
40 will be called i2c-dev.

47 bool "I2C Core debugging messages"
49 Say Y here if you want the I2C core to produce a bunch of debug
50 messages to the system log. Select this if you are having a
51 problem with I2C support and want to see more of what is going on.
54 bool "I2C Algorithm debugging messages"
56 Say Y here if you want the I2C algorithm drivers to produce a bunch
57 of debug messages to the system log. Select this if you are having
58 a problem with I2C support and want to see more of what is going
62 bool "I2C Bus debugging messages"
64 Say Y here if you want the I2C bus drivers to produce a bunch of
65 debug messages to the system log. Select this if you are having
66 a problem with I2C support and want to see more of what is going
70 bool "I2C Chip debugging messages"
72 Say Y here if you want the I2C chip drivers to produce a bunch of
73 debug messages to the system log. Select this if you are having
74 a problem with I2C support and want to see more of what is going
