NAME

SYNOPSIS

         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);

         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.

       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.

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.
