Based on linux 3.10.24 source code 参考/documentation/devicetree/Booting-without-of.txt文档 1.设备树(Device Tree)基本概念及作用 在内核源码中,存在大量对板级细节信息描述的代码。这些代码充斥在/arch/arm/plat-xxx和/arch/arm/mach-xxx目录,对内核而言这些platform设备、resource、i2c_board_info、spi_board...
所谓属性,其实就是成对出现的name和value。在Device Tree中,可描述的信息包括(原先这些信息大多被hard code到kernel中): CPU的数量和类别 内存基地址和大小 总线和桥 外设连接 中断控制器和中断使用情况 GPIO控制器和GPIO使用情况 Clock控制器和Clock使用情况 它基本上就是画一棵电路板上CPU、总线、设备组成的树,B...
