13   An I2C Address Translator (ATR) is a device with an I2C slave parent
14   ("upstream") port and N I2C master child ("downstream") ports, and
17   called the "alias" and is (potentially) different from the physical
22   i2c-alias-pool:
23     $ref: /schemas/types.yaml#/definitions/uint32-array
25       I2C alias pool is a pool of I2C addresses on the main I2C bus that can be
26       used to access the remote peripherals on the serializer's I2C bus. The
28       remote peripheral is assigned an alias from the pool, and transactions to
31       needed if there are no I2C addressable remote peripherals.
