1 /* 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.
