This does not do what you think it does!
It needs to be
items:
  - enum:
      - h6
      - h616
  - const: a64

I think this is not right, as a corresponding driver change is missing.
Either you're missing a clock driver patch or you didn't test your dts.
Given the bus binding, I suspect that latter.

Your commit message should mention why a fallback is not suitable here.

Thanks,
