* 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.
