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.
