+	 *
+	 * The first naive approach is to iterate over all p1 values acceptable
+	 * according to (1) and all mf values acceptable according to (2), and
+	 * stop at the first combination that fulfills (3), (4) and (5). This

+	 *
+	 * and round the minimum up to the nearest multiple of mf_inc. This will
+	 * 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
+	 *	ext_clock / (div * mf / p1) * m * mf <= out_clock_max

+	 *	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
