Yes, a derived divider is better.

As mentioned in other thread, the modeling of clock nodes (derived plus
gates) would bring in considerable (relative to complete driver) code, the
advantage being higher pixel clock resolution. Current use cases work
as per existing divider setting in driver. Hence now it seems a better
decision now is to proceed with logic as in v2 (not using clock nodes).
And later depending on the use case requirement, clock tree modeling can
be implemented.

Thanks for your input.
