Many camera sensor devices contain EEPROM chips that describe the properties of a given unit --- the data is specific to a given unit can thus is not stored e.g. in user space or the driver. Some sensors embed the EEPROM chip and it can be accessed through the sensor's I2C interface. This property is to be used for devices where the EEPROM chip is accessed through a different I2C address than the sensor. The intent is to later provide this information to the user space.
