+ I2C alias pool is a pool of I2C addresses on the main I2C bus that can be
+ used to access the remote peripherals on the serializer's I2C bus. The
+ addresses must be available, not used by any other peripheral. Each
+ remote peripheral is assigned an alias from the pool, and transactions to
+ that address will be forwarded to the remote peripheral, with the address
+ translated to the remote peripheral's real address. This property is not
+ needed if there are no I2C addressable remote peripherals.
