+ *
+ * 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

+ * defined by the combination of (2), (6) and (8). If the resulting mf
