This is prescribing driver details to the system-management node. The
reset-controller node should be removed, the #reset-cells moved up one
level, and the "nuvoton,ma35d1-sys" should match a driver that registers
an auxiliary device for reset functionality. Is anything besides child
nodes like 'reset-controller' using the syscon@40460000?

OK, I will modify it as:

    sys: system-management@40460000 {
        compatible = "nuvoton,ma35d1-sys", "syscon",;
        reg = <0x0 0x40460000 0x0 0x200>;
        #reset-cells = <1>;
        };
    };

And my reset driver will use compatible "nuvoton,ma35d1-sys", instead of "nuvoton,ma35d1-reset".
There' no other node like reset-controller.


Best regards,
Jack Huang
