All M1 Mac devices have 2 SoC connected USB-C ports and use cd321x USB type C port switch and power deliver controllers. I2c bus and addresses configuration are for all devices equal. The iMac (24-inch, 2021) has a configuration with 2 additional USB-C ports (j456) using two additional cd321x controllers.
