你可能喜欢openWRT的DTS文件配置--MT7620A
接上xx路由器的串口后有输出但无法输入，用示波器量下信号-----可能是uboot里面把RX引脚给配置了。
1.属性的定义采用property ＝ value的形式，“”字符串、&&32或64位值、[]二进制[0x01
2.用=赋值的才是节点属性，其他是子节点。
3.root节点的compitable属性供内核选择匹配机器码machinetype，其他节点的compitable属性供内核选择匹配对应的驱动
（如三星2416的lcd控制器节点，内核里面lcd的驱动有很多）
4.DTB文件头boot_paras_header,其中的magic字段用来标志Uboot传来的启动参数是DTB还是taglist(bootargs)
，xx_offset标志DTB在内存中的地址。
compatible：兼容的，相容的
{---------------------"/"表示根节点的名称，一个设备树只能有一个根节点多个文件中的根节点在编译时会被合并。
#address-cells =
&1&;---------------表示地址空间的个数，如系统有两片内存，那就需要两组数据来表示，ab表示内存1的空间 cd表示内存2空间。

例如一个在.dts文件中关于gpio资源的描述：
& gpio: gpio-controller@0 {
#gpio-cells = &2&;
& & & compatible
= "cavium,octeon-3860-gpio";
& & & reg =
&0x 0x100&;
根据其描述， 可知道gpio控制器的IO内存起始地址为：0x， 长度为0x100.
即从 0x 到 0xff.
在目标板里使用 &cat /proc/iomem
&可以看到：
/soc@0/gpio-controller@0
