	 struct device_attribute * dev_attrs;
	 const struct attribute_group ** dev_groups;
	 struct bin_attribute * dev_bin_attrs;
	 struct kobject * dev_kobj;

	 const void *(* namespace) (struct device *dev);
	 const struct dev_pm_ops * pm;
	 struct subsys_private * p;
       };

MEMBERS

       name
	   Name of the class.

       owner
	   The module owner.

       class_attrs
	   Default attributes of this class.

       dev_attrs
	   Default attributes of the devices belong to the class.

       dev_groups
	   Default attributes of the devices that belong to the class.

       dev_bin_attrs
	   Default binary attributes of the devices belong to the class.

       dev_kobj
	   The kobject that represents this class and links it into the hierarchy.

       dev_uevent
	   Called when a device is added, removed from this class, or a few other things that generate uevents to add the environment variables.

       devnode
	   Callback to provide the devtmpfs.

       class_release
	   Called to release this class.

       dev_release
	   Called to release the device.

       suspend
	   Used to put the device to sleep mode, usually to a low power state.

       resume
	   Used to bring the device from the sleep mode.

       ns_type
	   Callbacks so sysfs can detemine namespaces.

       namespace
	   Namespace of the device belongs to this class.

       pm
	   The default device power management operations of this class.

       p
	   The private data of the driver core, no one other than the driver core can touch this.

DESCRIPTION

       A class is a higher-level view of a device that abstracts out low-level implementation details. Drivers may see a SCSI disk or an ATA disk,
       but, at the class level, they are all simply disks. Classes allow user space to work with devices based on what they do, rather than how
       they are connected or how they work.

DEVICE_DRIVER(9) 				   Device drivers infrastructure				   STRUCT DEVICE_DRIVER(9)

NAME

       struct_device_driver - The basic device driver structure

SYNOPSIS

       struct device_driver {
	 const char * name;
	 struct bus_type * bus;
	 struct module * owner;
	 const char * mod_name;
	 bool suppress_bind_attrs;
	 const struct of_device_id * of_match_table;
	 const struct acpi_device_id * acpi_match_table;
	 int (* probe) (struct device *dev);
	 int (* remove) (struct device *dev);
	 void (* shutdown) (struct device *dev);
	 int (* suspend) (struct device *dev, pm_message_t state);
	 int (* resume) (struct device *dev);
	 const struct attribute_group ** groups;
	 const struct dev_pm_ops * pm;
	 struct driver_private * p;
       };

MEMBERS

       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.

       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.

DESCRIPTION

       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.
