+	 * restrict the number of mf values to be checked.
+	 *
+	 * Furthermore, conditions (4) and (5) only restrict the range of
+	 * acceptable p1 and mf values by modifying the minimum and maximum
+	 * limits. (5) can be expressed as
+	 *
+	 *	ext_clock / (div * mf / p1) * m * mf >= out_clock_min

+	 *	mf >= ext_clock * p1 / (int_clock_max * div)	(8)
+	 *	mf <= ext_clock * p1 / (int_clock_min * div)
+	 *
+	 * We can thus iterate over the restricted p1 range defined by the
+	 * combination of (1) and (7), and then compute the restricted mf range
+	 * defined by the combination of (2), (6) and (8). If the resulting mf

+ *
+ *  FM-Mono
+ *      should work. The stereo modes are backward compatible to FM-mono,
+ *      therefore FM-Mono should be allways available.
+ *
+ *  FM-Stereo (B/G, used in germany)
+ *      should work, with autodetect
+ *
+ *  FM-Stereo (satellite)
+ *      should work, no autodetect (i.e. default is mono, but you can
+ *      switch to stereo -- untested)
+ *
+ *  NICAM (B/G, L , used in UK, Scandinavia, Spain and France)
+ *      should work, with autodetect. Support for NICAM was added by

+ * 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.
