You need a max = 4 for P.

The manual says to give preference to K >= 2. I suggest swapping N/K and
leaving a note about it, so the actual K is in the inner loop (see ccu_nk.c)
of the factor calculation.

Same here.

You need a table for K. (Manual says K >= 2).

Even though the mux has only one valid parent, I suggest you still implement it,
in case some bogus value gets put in before the kernel loads.
