+ * Sanyo LM7001 Direct PLL Frequency Synthesizer
+ *    ??? See http://www.redsword.com/tjacobs/geeb/fmcard.htm
+ *
+ * The LM7001J and LM7001JM (used in Aztech/PackardBell cards) are PLL
+ * frequency synthesizer LSIs for tuners. These LSIs are software compatible
+ * with LM7000 (used in Radiotrack, Radioreveal RA300, some Mediaforte cards),
+ * but do not include an IF calculation circuit.
+ *
+ * The FM VCO circuit includes a high-speed programmable divider that can
+ * divide directly.
+ *
+ * Features:
+ * Seven reference frequencies: 1, 5, 9, 10, 25, 50, and 100 kHz;
+ * Band-switching outputs (3 bits);
+ * Controller clock output (400 kHz);
+ * Serial input circuit for data input (using the CE, CL and DATA pins).
+ *
+ * The LM7001J and LM7001JM have a 24-bit shift register.
