设备树常用结构体

常用结构体：
//某一节点
struct device_node {
const char *name;
const char *type;
phandle phandle;
const char *full_name;
struct fwnode_handle fwnode;

struct property *properties;
struct property *deadprops; /* removed properties */
struct device_node *parent;
struct device_node *child;
struct device_node *sibling;
struct kobject kobj;
unsigned long _flags;
void *data;
#if defined(CONFIG_SPARC)
const char *path_component_name;
unsigned int unique_id;
struct of_irq_controller *irq_trans;
#endif
}
//某一属性
struct property {
char *name;
int length;
void *value;
struct property *next;
unsigned long _flags;
unsigned int unique_id;
struct bin_attribute attr;
};
//带参节点
struct of_phandle_args {
struct device_node *np;
int args_count;
uint32_t args[MAX_PHANDLE_ARGS];
};
例子：
led0: cpu {
label = "user";
gpios = <&gpio5 1 GPIO_ACTIVE_LOW>;
default-state = "off";
};
其中device_node为cpu，led0为其别名，
property为具体某一个属性例如其中的label
