1 /* saa711x - Philips SAA711x video decoder driver
2 * This driver can work with saa7111, saa7111a, saa7113, saa7114,
3 * saa7115 and saa7118.
4 *
5 * Based on saa7114 driver by Maxim Yevtyushkin, which is based on
6 * the saa7111 driver by Dave Perks.

10 *
11 * Slight changes for video timing and attachment output by
12 * Wolfgang Scherr <scherr@net4you.net>
13 *
14 * Moved over to the linux >= 2.4.x i2c protocol (1/1/2003)
15 * by Ronald Bultje <rbultje@ronald.bitfreak.net>
16 *
17 * Added saa7115 support by Kevin Thayer <nufan_wfk at yahoo.com>
18 * (2/17/2003)
