956
 * @uniq: unique identification code for the device (if device has it)
957
 * @id: id of the device (struct input_id)
958
 * @evbit: bitmap of types of events supported by the device (EV_KEY,
959
 *      EV_REL, etc.)
960
 * @keybit: bitmap of keys/buttons this device has
961
 * @relbit: bitmap of relative axes for the device

 * @absbit: bitmap of absolute axes for the device
963
 * @mscbit: bitmap of miscellaneous events supported by the device
964
 * @ledbit: bitmap of leds present on the device
965
 * @sndbit: bitmap of sound effects supported by the device
966
 * @ffbit: bitmap of force feedback effects supported by the device
967
 * @swbit: bitmap of switches present on the device
968
 * @keycodemax: size of keycode table
969
 * @keycodesize: size of elements in keycode table
970
 * @keycode: map of scancodes to keycodes for this device
971
 * @setkeycode: optional method to alter current keymap, used to implement
972
 *      sparse keymaps. If not supplied default mechanism will be used
973
 * @getkeycode: optional method to retrieve current keymap. If not supplied
974
 *      default mechanism will be used
975
 * @ff: force feedback structure associated with the device if device
976
 *      supports force feedback effects
977
 * @repeat_key: stores key code of the last key pressed; used to implement
978
 *      software autorepeat
979
 * @timer: timer for software autorepeat
980
 * @sync: set to 1 when there were no new events since last EV_SYNC

 * @absflat: size of the center flat position (used by joydev)
991
 * @open: this method is called when the very first user calls
992
 *      input_open_device(). The driver must prepare the device
993
 *      to start generating events (start polling thread,
994
 *      request an IRQ, submit URB, etc.)
995
 * @close: this method is called when the very last user calls
996
 *      input_close_device().
997
 * @flush: purges the device. Most commonly used to get rid of force
998
 *      feedback effects loaded into the device when disconnecting
999
 *      from it
1000
 * @event: event handler for events sent _to_ the device, like EV_LED
1001
 *      or EV_SND. The device is expected to carry out the requested
1002
 *      action (turn on a LED, play sound, etc.) The call is protected
1003
 *      by @event_lock and must not sleep
1004
 * @grab: input handle that currently has the device grabbed (via
1005
 *      EVIOCGRAB ioctl). When a handle grabs a device it becomes sole
1006
 *      recipient for all input events coming from the device
1007
 * @event_lock: this spinlock is is taken when input core receives
1008
 *      and processes a new event for the device (in input_event()).
1009
 *      Code that accesses and/or modifies parameters of a device
1010
 *      (such as keymap or absmin, absmax, absfuzz, etc.) after device
1011
 *      has been registered with input core must take this lock.
1012
 * @mutex: serializes calls to open(), close() and flush() methods
1013
 * @users: stores number of users (input handlers) that opened this
1014
 *      device. It is used by input_open_device() and input_close_device()
1015
 *      to make sure that dev->open() is only called when the first
1016
 *      user opens device and dev->close() is called when the very
1017
 *      last user closes the device
1018
 * @going_away: marks devices that are in a middle of unregistering and
1019
 *      causes input_open_device*() fail with -ENODEV.
1020
 * @dev: driver model's view of this device
1021
 * @cdev: union for struct device pointer
1022
 * @h_list: list of input handles associated with the device. When
1023
 *      accessing the list dev->mutex must be held
1024
 * @node: used to place the device onto input_dev_list

1327
 * @max_effects: maximum number of effects supported by device

 * @effects: pointer to an array of effects currently loaded into device
1329
 * @effect_owners: array of effect owners; when file handle owning

 * Every force-feedback device must implement upload() and playback()
1333

1334
 * only be implemented if driver sets up FF_GAIN and FF_AUTOCENTER
1335
 * bits.
