struct device_driver

/**
 * struct device_driver - The basic device driver structure
 * @name:	Name of the device driver.
 驱动名称
 * @bus:	The bus which the device of this driver belongs to.
 设备的驱动属于哪种总线
 * @owner:	The module owner.
 模型拥有者
 * @mod_name:	Used for built-in modules.
 为了built-in模型使用
 * @suppress_bind_attrs: Disables bind/unbind via sysfs.
 禁止使能绑定文件系统
 * @of_match_table: The open firmware table.
 开放固件条目
 * @probe:	Called to query the existence of a specific device,
 *		whether this driver can work with it, and bind the driver
 *		to a specific device.
 用于查询确定的设备，进而确定驱动是否能工作，并且绑定设备
 * @remove:	Called when the device is removed from the system to
 *		unbind a device from this driver.
 当设备移除的时候，解绑设备和驱动
 * @shutdown:	Called at shut-down time to quiesce the device.
 关闭的时候静止设备
 * @suspend:	Called to put the device to sleep mode. Usually to a
 *		low power state.
 让设备进入休眠模式，常常是进入低功耗模式
 * @resume:	Called to bring a device from sleep mode.
 从休眠模式唤醒
 * @groups:	Default attributes that get created by the driver core
 *		automatically.
 驱动核心创建的默认属性
 * @pm:		Power management operations of the device which matched
 *		this driver.
 符合这个驱动的电源管理操作
 * @p:		Driver core's private data, no one other than the driver
 *		core can touch this.
 *驱动核心私有数据，除了驱动核心其他任何资源不能操作此数据
 * The device driver-model tracks all of the drivers known to the system.
 * The main reason for this tracking is to enable the driver core to match
 * up drivers with new devices. Once drivers are known objects within the
 * system, however, a number of other things become possible. Device drivers
 * can export information and configuration variables that are independent
 * of any specific device.

 //设备驱动模型遍历所有系统已知的驱动，这样做的主要目的是让驱动和兴匹配新设备
 //一旦驱动被系统获取到，一系列的事情都变得可能，设备驱动能输出信息和配置变量
 //而这一切都不依赖于特定的设备
