This enables aforementioned hardware to act as an I2C slave that can be accessed by a remote I2C master. I have tested this patchset successfully on an ATSAMA5D27 with the i2c-slave-eeprom backend for some time and I'm convinced that it works stable enough to be reviewed by you. Since I am a newcomer to kernel coding, I really would like to hear your comments on this patchset.
