What is the AT18 on I2C4 Bus?

I have a look at the DTS, and I2C4 describes 3 devices.

fusb0: fusb30x@22 {
gsl3680: gsl3680@40 {
mpu6050: mpu@68 {

On Schematic: AT18 does not have address on the I2C Bus, but it has a reference to 'Encryption'.
AT18 is a 8pin device according to schematic and PCB. It is also NC which mean it does not loaded or populated on the PCB.

My question is: What is this Mysterious AT18 used for?

Thank you.

As the name suggests, it is reserved for some clients to support encryption.
