13 I2C (pronounce: I-squared-C) is a slow serial bus protocol used in
15 or System Management Bus is a subset of the I2C protocol. More
19 Both I2C and SMBus are supported here. You will need this for
22 If you want I2C support, you should say Y here and also to the
25 This I2C support can also be built as a module. If so, the module
29 bool "ACPI I2C Operation region support"
30 depends on I2C=y && ACPI
33 Say Y here if you want to enable ACPI I2C operation region support.
34 Operation Regions allow firmware (BIOS) code to access I2C slave devices,
35 such as smart batteries through an I2C host controller driver.
37 if I2C
52 tristate "I2C device interface"
56 programs use the I2C bus. Information on how to do this is
63 tristate "I2C bus multiplexing support"
65 Say Y here if you want the I2C core to support the ability to
66 handle multiplexed I2C bus topologies, by presenting each
67 multiplexed segment as a I2C adapter.
75 tristate "I2C Address Translator (ATR) support" if COMPILE_TEST
77 Enable support for I2C Address Translator (ATR) chips.
79 An ATR allows accessing multiple I2C busses from a single
87 Some I2C bus drivers require so-called "I2C algorithm" modules
89 I2C interfaces. This option will autoselect them so that you don't
93 modules, for example for use with external I2C bus drivers.
100 Say Y here if you want support for SMBus extensions to the I2C

123 bool "I2C slave support"
125 This enables Linux to act as an I2C slave device. Note that your I2C
132 tristate "I2C eeprom slave driver"
134 This backend makes Linux behave like an I2C EEPROM. Please read
138 tristate "I2C eeprom testunit driver"
140 This backend can be used to trigger test cases for I2C bus masters
148 bool "I2C Core debugging messages"
150 Say Y here if you want the I2C core to produce a bunch of debug
152 problem with I2C support and want to see more of what is going on.
