Currently the FLL configuration is calculated before it is known which FLL path the configuration will be applied to. Newer versions of the IP have differences in the configuration required for each FLL path, which makes it complicated to calculate the FLL configuration in advance.
This patch simply checks the validity of a requested input and output frequency before we know which FLL path they will be applied to and saves the actual calculation of the configuration until we know where the settings will be applied.
I'll apply this but are you sure that this validity check is actually accurate? For some of the devices there were input/output configurations that couldn't be reached due to constraints in the system even though both input and output were in range.
I will look over it again to make sure.
Thanks, Charles
