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