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
