I think you could post this independently as well.

There is a strong desire to use standard node names and
clock is recommended. even though there are tons of fixed-clock
compatible clocks in the kernel today, as of v5.10-rc1:

$ git grep fixed-clock- arch/arm64/boot/dts/
$ git grep fixed-clock- arch/arm/boot/dts/

As a node name is not used. Do you want to see how other
platforms are trying to resolve similar issues?
