+/* Calculate clock fractional divider value from ref and target frequencies.
+ * This is for a U7.1 format. This is not well written up in the book and
+ * there have been some questions about this macro, so here we go.
+ * U7.1 format is defined as (ddddddd+1) + (h*.5)
+ * The lowest order bit is actually a fractional bit.
+ * Hence, the divider can be thought of as 9 bits.
+ * So:
+ * divider = ((ref/freq) << 1 - 1) (upper 7 bits) |
+ * (ref/freq & 1) (low order half-bit)
+ * however we can't do fractional arithmetic ... these are integers!
+ * So we normalize by shifting the result left 1 bit, and extracting
+ * ddddddd and h directly to the returned u8.
+ * divider = 2*(ref/freq);
+ * We want to
+ * preserve 7 bits of divisor and one bit of fraction, in 8 bits, as well as
+ * subtract one from ddddddd. Since we computed ref*2, the dddddd is now nicely
