| /** |
| * struct input_dev - represents an input device |
| * @name: name of the device |
| * @phys: physical path to the device in the system hierarchy |
| * @uniq: unique identification code for the device (if device has it) |
| * @id: id of the device (struct input_id) |
| * @propbit: bitmap of device properties and quirks |
| * @evbit: bitmap of types of events supported by the device (EV_KEY, |
| * EV_REL, etc.) |
| * @keybit: bitmap of keys/buttons this device has |
| * @relbit: bitmap of relative axes for the device |
| * @absbit: bitmap of absolute axes for the device |
| * @mscbit: bitmap of miscellaneous events supported by the device |
| * @ledbit: bitmap of leds present on the device |
| * @sndbit: bitmap of sound effects supported by the device |
| * @ffbit: bitmap of force feedback effects supported by the device |
| * @swbit: bitmap of switches present on the device |
| * @hint_events_per_packet: average number of events generated by the |
| * device in a packet (between EV_SYN/SYN_REPORT events). Used by |
| * event handlers to estimate size of the buffer needed to hold |
| * events. |
| * @keycodemax: size of keycode table |
| * @keycodesize: size of elements in keycode table |
| * @keycode: map of scancodes to keycodes for this device |
| * @getkeycode: optional legacy method to retrieve current keymap. |
| * @setkeycode: optional method to alter current keymap, used to implement |
| * sparse keymaps. If not supplied default mechanism will be used. |
| * The method is being called while holding event_lock and thus must |
| * not sleep |
| * @ff: force feedback structure associated with the device if device |
| * supports force feedback effects |
| * @repeat_key: stores key code of the last key pressed; used to implement |
| * software autorepeat |
| * @timer: timer for software autorepeat |
| * @rep: current values for autorepeat parameters (delay, rate) |
| * @mt: pointer to multitouch state |
| * @absinfo: array of &struct input_absinfo elements holding information |
| * about absolute axes (current value, min, max, flat, fuzz, |
| * resolution) |
| * @key: reflects current state of device's keys/buttons |
| * @led: reflects current state of device's LEDs |
| * @snd: reflects current state of sound effects |
| * @sw: reflects current state of device's switches |
| * @open: this method is called when the very first user calls |
| * input_open_device(). The driver must prepare the device |
| * to start generating events (start polling thread, |
| * request an IRQ, submit URB, etc.) |
| * @close: this method is called when the very last user calls |
| * input_close_device(). |
| * @flush: purges the device. Most commonly used to get rid of force |
| * feedback effects loaded into the device when disconnecting |
| * from it |
| * @event: event handler for events sent _to_ the device, like EV_LED |
| * or EV_SND. The device is expected to carry out the requested |
| * action (turn on a LED, play sound, etc.) The call is protected |
| * by @event_lock and must not sleep |
| * @grab: input handle that currently has the device grabbed (via |
| * EVIOCGRAB ioctl). When a handle grabs a device it becomes sole |
| * recipient for all input events coming from the device |
| * @event_lock: this spinlock is is taken when input core receives |
| * and processes a new event for the device (in input_event()). |
| * Code that accesses and/or modifies parameters of a device |
| * (such as keymap or absmin, absmax, absfuzz, etc.) after device |
| * has been registered with input core must take this lock. |
| * @mutex: serializes calls to open(), close() and flush() methods |
| * @users: stores number of users (input handlers) that opened this |
| * device. It is used by input_open_device() and input_close_device() |
| * to make sure that dev->open() is only called when the first |
| * user opens device and dev->close() is called when the very |
| * last user closes the device |
| * @going_away: marks devices that are in a middle of unregistering and |
| * causes input_open_device*() fail with -ENODEV. |
| * @sync: set to %true when there were no new events since last EV_SYN |
| * @dev: driver model's view of this device |
| * @h_list: list of input handles associated with the device. When |
| * accessing the list dev->mutex must be held |
| * @node: used to place the device onto input_dev_list |

| * it may not sleep |
| * @filter: similar to @event; separates normal event handlers from |
| * "filters". |
| * @match: called after comparing device's id with handler's id_table |
| * to perform fine-grained matching between device and handler |
| * @connect: called when attaching a handler to an input device |
| * @disconnect: disconnects a handler from input device |
| * @start: starts handler for given handle. This function is called by |

| * @fops: file operations this driver implements |
| * @minor: beginning of range of 32 minors for devices this driver |

| * the device. |
| * |

| * allows filters to run first and will not pass event to regular handlers |
| * if any of the filters indicate that the event should be filtered (by |
| * returning %true from their filter() method). |
| * |
| * Note that input core serializes calls to connect() and disconnect() |
