+ *

+ * NTSC Standards", Proceedings of the I-R-E, January 1954, pp 81-83
+ *
+ * As Mike Bradley has rightly pointed out, it's not the exact crystal
+ * frequency that matters, only that all parts of the driver and
+ * firmware are using the same value (close to the ideal value).
+ *
+ * Since I have a strong suspicion that, if the firmware ever assumes a
+ * crystal value at all, it will assume 28.636360 MHz, the crystal
+ * freq used in calculations in this driver will be:
+ *
+ * xtal_freq = 28.636360 MHz
+ *
+ * an error of less than 0.13 ppm which is way, way better than any off
+ * the shelf crystal will have for accuracy anyway.
+ *
+ * Below I aim to run the PLLs' VCOs near 400 MHz to minimze errors.
+ *
+ * Many thanks to Jeff Campbell and Mike Bradley for their extensive
+ * investigation, experimentation, testing, and suggested solutions of
