13 I2C (pronounce: I-squared-C) is a slow serial bus protocol used in

47 Say Y here if you intend to run lm-sensors 3.1.1 or older, or any
48 other user-space package which expects i2c adapters to be class
54 Say Y here to use i2c-* device files, usually found in the /dev
55 directory on your system. They make it possible to have user-space
56 programs use the I2C bus. Information on how to do this is
57 contained in the file <file:Documentation/i2c/dev-interface.rst>.
60 will be called i2c-dev.

78 Some I2C bus drivers require so-called "I2C algorithm" modules
79 to work. These are basically software-only abstractions of generic
84 modules, for example for use with external I2C bus drivers.
