Could you explain why please? Are greybus I2C bus masters different from physical I2C bus masters?

I don't think you need to put the DT overlay in the EEPROM. All you need to do is translate the manifest into DT for those simple devices which can be described by the limited manifest format. For more complex devices, you use the ID to go find a DT fragment which describes the board, and skip the manifest to DT transformation. Andrew
