Dslave-interface.rst2 Linux I2C slave interface description
5 by Wolfram Sang <wsa@sang-engineering.com> in 2014-15
7 Linux can also be an I2C slave if the I2C controller in use has slave
8 functionality. For that to work, one needs slave support in the bus driver plus
10 example for the latter is the slave-eeprom driver, which acts as a dual memory
12 EEPROM, the Linux I2C slave can access the content via sysfs and handle data as
16 use a character device, be in-kernel only, or something completely different::
19 e.g. sysfs I2C slave events I/O registers
