Linux Kernel设备驱动模型之 struct device_node 严格说,此数据结构不是设备模型中的,它是一个DTS中节点对应的内存中设备描述,一般此 对象代表一个设备。 struct device_node { const char *name; const char *type; phandle phandle; const char *full_name; struct fwnode_handle fwnode; struct property *prop...

struct node是结点的意思。在编程中struct //是C中的结构体的关键词。如： stuct node{ /* node 相当于结构体的类型,关键是！其实在C中stuct node 才相当于一个数据类型，如int ，如在定一个变量时，要用 struct node xxx,而不是 node xxx 这就是关键。/ int a;...} a; // a是结构...

每个phy 芯片会创建一个 struct phy_device 类型的设备,对应的有 struct phy_driver 类型的驱动,这两者实际上是挂载在 mdio_bus_type 总线上的,mac 会被注册成 struct net_device。 phy_devicestructphy_device{ structphy_driver*drv;// PHY设备驱动 ...
