In the hi3519.dtsi file, there is a system-controller device node described like below:
sysctrl: system-controller@12010000 {
compatible = "hisilicon,hi3519-sysctrl", "syscon";
reg = <0x12010000 0x1000>;
};
Do you mean that I should remove "hisilicon,hi3519-sysctrl" and just use "syscon" as the
compatible string?
If I want to add "hisilicon,hi3519-sysctrl" for hi3519. where should I put this binding?
Could you give some suggestions? Thank you very much!
