Thus, change it to the value which is true for clock 1200MHz. 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).
