What is the new hardware block (compared with other SoC) need this clock? Why this is different than other SoC? Is this case the same as [1]? If so, I think you should not add this clock.

DPI for MT8365 is compatible with MT8192 but requires an additional clock. Modify the documentation to requires this clock only on MT8365 SoCs.
