- * 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
