Linux Kernel设备驱动模型之 struct device

设备驱动描述： /**  * struct device_driver - The basic device driver structure  * @name: Name of the device driver.  * @bus: The bus which the device of this driver belongs to.  * @owner: The module owner.  * @mod_name: Used for built-in modules.  * @suppress_bind_attrs: Disables bind/unbind via sysfs.  * @probe_type: Type of the probe (synchronous or asynchronous) to use.  * @of_match_table: The open firmware table.  * @acpi_match_table: The ACPI match table.  * @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.  * @remove: Called when the device is removed from the system to  *  unbind a device from this driver.  * @shutdown: Called at shut-down time to quiesce the device.  * @suspend: Called to put the device to sleep mode. Usually to a  *  low power state.  * @resume: Called to bring a device from sleep mode.  * @groups: Default attributes that get created by the driver core  *  automatically.  * @pm:  Power management operations of the device which matched  *  this driver.  * @p:  Driver core's private data, no one other than the driver  *  core can touch this.  *  * 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.  */ struct device_driver {  const char  *name;  struct bus_type  *bus;
