TX1 camera has a chip on what role

We design the camera, found TX1 camera has a U1 chip, part number is CAT24C02HU4IGT3A, chip-related parameters are IC I2C CMOS SERIAL EEPROM 2Kb 1.7V TO 5.5V 100KHz MAX STANDARD 400KHz MAX FAST UDFN-8-EP; to ask this What is the role of the chip?

I had the same question before.
The following is from Nvidia Tegra Linux Driver Package developer Guide:

Many cameras (e.g., Pi cameras) work for TX1 without EEPROM.
