Newbie ACPI question. What is the definition of an address?

In this cause, we are talking about an address of a device on an MDIO
bus. It takes a value between 0 and 31.

How are IC2 device addresses represented in ACPI? MDIO devices and I2C
devices are pretty similar. So it would make sense to use the same as
what I2C uses.
