I think this is getting slightly too granular. It seems you are
solving the same problem (or very small subset of the same problem) as
in patch 22:
https://patchwork.kernel.org/patch/11043849/

Please combine such changes per IP block, unless you have really
reproducible different issues (e.g. reproducible different performance
problem or OOPS, but not just what clk_summary prints). I imagine that
you align entire subsystem (DISP) buses to real clock frequencies (or
to match real frequencies, or to achieve more granular scaling, or to
get slightly better performance).

Best regards,
Krzysztof
