36 * Usage:
37 *
38 * Register a map variable, and fill it with a character set:
39 * static SEG7_DEFAULT_MAP(map_seg7);
40 *
41 *
42 * Then use for conversion:

21 * Description:
22 * Driver for the USB-P1K voip usb phone.
23 * This device is produced by Yealink Network Technology Co Ltd
24 * but may be branded under several names:
25 * - Yealink usb-p1k
26 * - Tiptel 115
27 * - ...
28 *
29 * This driver is based on:
30 * - the usbb2k-api http://savannah.nongnu.org/projects/usbb2k-api/
31 * - information from http://memeteau.free.fr/usbb2k
32 * - the xpad-driver drivers/usb/input/xpad.c
33 *
34 * Thanks to:
35 * - Olivier Vandorpe, for providing the usbb2k-api.
36 * - Martin Diehl, for spotting my memory allocation bug.
37 *
38 * History:
39 * 20050527 henk First version, functional keyboard. Keyboard events
40 * will pop-up on the ../input/eventX bus.
41 * 20050531 henk Added led, LCD, dialtone and sysfs interface.
42 * 20050610 henk Cleanups, make it ready for public consumption.
43 * 20050630 henk Cleanups, fixes in response to comments.
44 * 20050701 henk sysfs write serialisation, fix potential unload races
45 * 20050801 henk Added ringtone, restructure USB
46 * 20050816 henk Merge 2.6.13-rc6
