1 | /* |
2 | * saa717x - Philips SAA717xHL video decoder driver | |
3 | * | |
4 | * Based on the saa7115 driver | |
5 | * | |
6 | * Changes by Ohta Kyuma <alpha292@bremen.or.jp> | |
7 | * - Apply to SAA717x,NEC uPD64031,uPD64083. (1/31/2004) | |
8 | * | |
9 | * Changes by T.Adachi (tadachi@tadachi-net.com) | |
10 | * - support audio, video scaler etc, and checked the initialize sequence. | |
11 | * | |
12 | * Cleaned up by Hans Verkuil <hverkuil@xs4all.nl> | |
13 | * | |
14 | * Note: this is a reversed engineered driver based on captures from | |
15 | * the I2C bus under Windows. This chip is very similar to the saa7134, | |
16 | * though. Unfortunately, this driver is currently only working for NTSC. | |
