+ * 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.
