1001 * @name: name of the device
1002 * @phys: physical path to the device in the system hierarchy
1003 * @uniq: unique identification code for the device (if device has it)
1004 * @id: id of the device (struct input_id)
1005 * @evbit: bitmap of types of events supported by the device (EV_KEY,
1006 * EV_REL, etc.)
1007 * @keybit: bitmap of keys/buttons this device has
1008 * @relbit: bitmap of relative axes for the device
1009 * @absbit: bitmap of absolute axes for the device
1010 * @mscbit: bitmap of miscellaneous events supported by the device
1011 * @ledbit: bitmap of leds present on the device
1012 * @sndbit: bitmap of sound effects supported by the device
1013 * @ffbit: bitmap of force feedback effects supported by the device
1014 * @swbit: bitmap of switches present on the device
1015 * @keycodemax: size of keycode table
1016 * @keycodesize: size of elements in keycode table
1017 * @keycode: map of scancodes to keycodes for this device
1018 * @setkeycode: optional method to alter current keymap, used to implement
1019 * sparse keymaps. If not supplied default mechanism will be used
1020 * @getkeycode: optional method to retrieve current keymap. If not supplied
1021 * default mechanism will be used
1022 * @ff: force feedback structure associated with the device if device
1023 * supports force feedback effects
1024 * @repeat_key: stores key code of the last key pressed; used to implement
1025 * software autorepeat
1026 * @timer: timer for software autorepeat
1027 * @sync: set to 1 when there were no new events since last EV_SYNC
1028 * @abs: current values for reports from absolute axes
1029 * @rep: current values for autorepeat parameters (delay, rate)
1030 * @key: reflects current state of device's keys/buttons
1031 * @led: reflects current state of device's LEDs
1032 * @snd: reflects current state of sound effects
1033 * @sw: reflects current state of device's switches
1034 * @absmax: maximum values for events coming from absolute axes
1035 * @absmin: minimum values for events coming from absolute axes
1036 * @absfuzz: describes noisiness for axes
1037 * @absflat: size of the center flat position (used by joydev)
1038 * @open: this method is called when the very first user calls
1039 * input_open_device(). The driver must prepare the device
1040 * to start generating events (start polling thread,
1041 * request an IRQ, submit URB, etc.)
1042 * @close: this method is called when the very last user calls
1043 * input_close_device().
1044 * @flush: purges the device. Most commonly used to get rid of force
1045 * feedback effects loaded into the device when disconnecting
1046 * from it
1047 * @event: event handler for events sent _to_ the device, like EV_LED
1048 * or EV_SND. The device is expected to carry out the requested
1049 * action (turn on a LED, play sound, etc.) The call is protected
1050 * by @event_lock and must not sleep
1051 * @grab: input handle that currently has the device grabbed (via
1052 * EVIOCGRAB ioctl). When a handle grabs a device it becomes sole
1053 * recipient for all input events coming from the device
1054 * @event_lock: this spinlock is is taken when input core receives
1055 * and processes a new event for the device (in input_event()).
1056 * Code that accesses and/or modifies parameters of a device
1057 * (such as keymap or absmin, absmax, absfuzz, etc.) after device
1058 * has been registered with input core must take this lock.
1059 * @mutex: serializes calls to open(), close() and flush() methods
1060 * @users: stores number of users (input handlers) that opened this
1061 * device. It is used by input_open_device() and input_close_device()
1062 * to make sure that dev->open() is only called when the first
1063 * user opens device and dev->close() is called when the very
1064 * last user closes the device
1065 * @going_away: marks devices that are in a middle of unregistering and
1066 * causes input_open_device*() fail with -ENODEV.
1067 * @dev: driver model's view of this device
1068 * @h_list: list of input handles associated with the device. When
1069 * accessing the list dev->mutex must be held
1070 * @node: used to place the device onto input_dev_list

1377 * methods; erase() is optional. set_gain() and set_autocenter() need
1378 * only be implemented if driver sets up FF_GAIN and FF_AUTOCENTER
1379 * bits.
