Like this? 

aon_syscon: syscon@...10000 {
	compatible = "starfive,jh7110-aon-syscon", "syscon", "starfive,jh7110-aon-pmu";
	reg = <0x0 0x17010000 0x0 0x1000>;
	#power-domain-cells = <1>;
};

If right? I will tell the syscon patch's owner delete the "simple-mfd" in aon_syscon node.

Best regards,
Krzysztof
