- * Description:
- *   Driver for the USB-P1K voip usb phone.
- *   This device is produced by Yealink Network Technology Co Ltd
- *   but may be branded under several names:
- *	- Yealink usb-p1k
- *	- Tiptel 115
- *	- ...
- *
- * This driver is based on:
- *   - the usbb2k-api	http://savannah.nongnu.org/projects/usbb2k-api/
- *   - information from	http://memeteau.free.fr/usbb2k
- *   - the xpad-driver	drivers/usb/input/xpad.c
- *
- * Thanks to:
- *   - Olivier Vandorpe, for providing the usbb2k-api.
- *   - Martin Diehl, for spotting my memory allocation bug.
- *
- * History:
- *   20050527 henk	First version, functional keyboard. Keyboard events
- *			will pop-up on the ../input/eventX bus.
- *   20050531 henk	Added led, LCD, dialtone and sysfs interface.
- *   20050610 henk	Cleanups, make it ready for public consumption.
- *   20050630 henk	Cleanups, fixes in response to comments.
- *   20050701 henk	sysfs write serialisation, fix potential unload races
- *   20050801 henk	Added ringtone, restructure USB
- *   20050816 henk	Merge 2.6.13-rc6
