1144 * @private: driver-specific data
Dmitry Torokhov80064792007-08-30 00:22:11 -04001145 * @event: event handler. This method is being called by input core with
1146 * interrupts disabled and dev->event_lock spinlock held and so
1147 * it may not sleep
Dmitry Torokhovc7e8dc62006-07-06 00:21:03 -04001148 * @connect: called when attaching a handler to an input device
1149 * @disconnect: disconnects a handler from input device
1150 * @start: starts handler for given handle. This function is called by
1151 * input core right after connect() method and also when a process
1152 * that "grabbed" a device releases it
1153 * @fops: file operations this driver implements
1154 * @minor: beginning of range of 32 minors for devices this driver
1155 * can provide
1156 * @name: name of the handler, to be shown in /proc/bus/input/handlers
1157 * @id_table: pointer to a table of input_device_ids this driver can
1158 * handle
Dmitry Torokhov80064792007-08-30 00:22:11 -04001159 * @blacklist: pointer to a table of input_device_ids this driver should
Dmitry Torokhovc7e8dc62006-07-06 00:21:03 -04001160 * ignore even if they match @id_table
1161 * @h_list: list of input handles associated with the handler
1162 * @node: for placing the driver onto input_handler_list
Dmitry Torokhov80064792007-08-30 00:22:11 -04001163 *
1164 * Input handlers attach to input devices and create input handles. There
1165 * are likely several handlers attached to any given input device at the
1166 * same time. All of them will get their copy of input event generated by
1167 * the device.
1168 *
1169 * Note that input core serializes calls to connect() and disconnect()
1170 * methods.
