No, the impact on speed from DFSR is pretty small so it will be close enough.
How small?
From the app note: divisor = B * (A + ((3*C)/B)*2);
C is dfsr and 10 <= A <= 30, 16 <= B <= 2048 Considering the actual speed may be way lower the requested speed I think this is small enough.
Once we have the new procedure in place, we can calculate the exact divisor so the need for extra CONFIG_ options goes away.
