Yes, "starfive,jh7110-aon-pmu" is a child-node of "starfive,jh7110-aon-syscon". In my opinion, "0x17010000" is "aon-syscon" on JH7110 SoC, and this "aon-pmu" is just a part of "aon-syscon" function, so I think it is inappropriate to make "aon-syscon" to a power domain controller. I think using the child-node description is closer to JH7110 SoC.
