STRUCT 
INPUT_POLLED_(9) 					  Input Subsystem					   STRUCT INPUT_POLLED_(9)

NAME

       struct_input_polled_dev - simple polled input device

SYNOPSIS

       struct input_polled_dev {
	 void * private;
	 void (* open) (struct input_polled_dev *dev);
	 void (* close) (struct input_polled_dev *dev);
	 void (* poll) (struct input_polled_dev *dev);
	 unsigned int poll_interval;
	 unsigned int poll_interval_max;
	 unsigned int poll_interval_min;
	 struct input_dev * input;
       };

MEMBERS

       private
	   private driver data.

       open
	   driver-supplied method that prepares device for polling (enabled the device and maybe flushes device state).

       close
	   driver-supplied method that is called when device is no longer being polled. Used to put device into low power mode.

       poll
	   driver-supplied method that polls the device and posts input events (mandatory).

       poll_interval
	   specifies how often the poll method should be called. Defaults to 500 msec unless overridden when registering the device.

       poll_interval_max
	   specifies upper bound for the poll interval. Defaults to the initial value of poll_interval.

       poll_interval_min
	   specifies lower bound for the poll interval. Defaults to 0.

       input
	   input device structure associated with the polled device. Must be properly initialized by the driver (id, name, phys, bits).

DESCRIPTION

       Polled input device provides a skeleton for supporting simple input devices that do not raise interrupts but have to be periodically
       scanned or polled to detect changes in their state.

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.
