设备树的树形结构到底是怎样体现的？

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，整个数据的组织方式和linux中的文件夹管理方式类型，都是树形结构体；
(2)上面只是从宏观上表示设备树的数据组织形式，更多细节参考博客：《linux内核启动阶段对设备树的解析》；
