| 6 | This is a proof-of-concept backend which acts like an EEPROM on the connected |
| 7 | I2C bus. The memory contents can be modified from userspace via this file |
| 8 | located in sysfs: |
| 9 | |
| 10 | /sys/bus/i2c/devices/<device-directory>/slave-eeprom |
| 11 | |
| 12 | As of 2015, Linux doesn't support poll on binary sysfs files, so there is no |
| 13 | notification when another master changed the content. |
