Dgpio.txt131 对于一个 GPIO，系统应该做的第一件事情就是通过 gpio_request()
197 一个之前通过 gpio_request 分配到的有效 GPIO 编号):
222 gpio_request()
240 int gpio_request(unsigned gpio, const char *label);
245 将无效的 GPIO 编码传递给 gpio_request()会导致失败，申请一个已使用这个
246 函数声明过的 GPIO 也会失败。gpio_request()的返回值必须检查。你应该在
273 gpio_request()前将这类细节配置好，例如使用 pinctrl 子系统的映射表，
284 * 其他和 gpio_request()的参数和返回值相同
629 内核代码可以明确地管理那些已通过 gpio_request()申请的 GPIO 的导出:
