2 * Mars MR97310A library
3 *
4 * The original mr97310a driver, which supported the Aiptek Pencam VGA+, is
5 * Copyright (C) 2009 Kyle Guinn <elyk03@gmail.com>
6 *
7 * Support for the MR97310A cameras in addition to the Aiptek Pencam VGA+
8 * and for the routines for detecting and classifying these various cameras,
9 * is Copyright (C) 2009 Theodore Kilgore <kilgota@auburn.edu>
10 *
11 * Support for the control settings for the CIF cameras is
12 * Copyright (C) 2009 Hans de Goede <hdegoede@redhat.com> and
13 * Thomas Kaiser <thomas@kaiser-linux.li>
14 *
15 * Support for the control settings for the VGA cameras is
16 * Copyright (C) 2009 Theodore Kilgore <kilgota@auburn.edu>
17 *
18 * Several previously unsupported cameras are owned and have been tested by
19 * Hans de Goede <hdegoede@redhat.com> and
20 * Thomas Kaiser <thomas@kaiser-linux.li> and
21 * Theodore Kilgore <kilgota@auburn.edu> and
22 * Edmond Rodriguez <erodrig_97@yahoo.com> and
23 * Aurelien Jacobs <aurel@gnuage.org>
24 *
25 * The MR97311A support in gspca/mars.c has been helpful in understanding some
26 * of the registers in these cameras.
