   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.
