How is the tree structure of the device tree reflected?

1、dts示例源码

/ {
    
	model = "Hisilicon HI3516DV300 DEMO Board";
	compatible = "hisilicon,hi3516dv300";
	
	memory {
    
		device_type = "memory";
		reg = <0x82000000 0x20000000>;
	};
	
	 chosen {
    
        bootargs = "console=ttySAC2,115200n8 root=/dev/nfs nfsroot=192.168.0.101:/home/run/work/rootfs/";
    }; 
    
	cpus {
    
		#address-cells = <1>;
		#size-cells = <0>;
		enable-method = "hisilicon,hi3516dv300";

		[email protected]0 {
    
			device_type = "cpu";
			compatible = "arm,cortex-a7";
			clock-frequency = <HI3516DV300_FIXED_1000M>;
			reg = <0>;
		};
		[email protected]1 {
    
			device_type = "cpu";
			compatible = "arm,cortex-a7";
			clock-frequency = <HI3516DV300_FIXED_1000M>;
			reg = <1>;
		};
	};
};

2、转换成树形结构

(1)"/"是根节点,The way the entire data is organized andlinuxThe type of folder management method in ,are tree structures;
(2)The above only represents the data organization form of the device tree from a macro level,For more details refer to the blog：《linuxThe parsing of the device tree during the kernel startup phase》;
