27 Families have unique hardware silicon identifiers within the SoC.
31 - compatible: "aspeed,silicon-id" or:
32 "aspeed,ast2400-silicon-id" or
33 "aspeed,ast2500-silicon-id" or
34 "aspeed,ast2600-silicon-id"
36 - reg: offset and length of the silicon id information
37 optionally, a second offset and length describes the unique chip id
39 The reg should be the unique silicon id register, and
40 not backwards compatible one in eg. the 2600.
