* saa717x - Philips SAA717xHL video decoder driver |
|
* |
|
* Based on the saa7115 driver |
|
* |
|
* Changes by Ohta Kyuma <[email protected]> |
|
* - Apply to SAA717x,NEC uPD64031,uPD64083. (1/31/2004) |
|
* |
|
* Changes by T.Adachi ([email protected]) |
|
* - support audio, video scaler etc, and checked the initialize sequence. |
|
* |
|
* Cleaned up by Hans Verkuil <[email protected]> |
|
* |
|
* 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. |
