BUS_REGISTER(9) 					   Device drivers infrastructure					   BUS_REGISTER(9)

NAME

       bus_register - register a driver-core subsystem

SYNOPSIS

       int bus_register(struct bus_type * bus);

ARGUMENTS

       bus
	   bus to register

DESCRIPTION

       Once we have that, we register the bus with the kobject infrastructure, then register the children subsystems it has: the devices and
       drivers that belong to the subsystem.

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;

	 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.
