Really? Looks automated... Care to provide any links to effects of
internal review?

Just open your bindings and take a look how it is done there...
This applies everywhere

There should be. What's the point? Clocks are internal part of SoC and
not really re-usable piece of hardware.

The reason is that the number of fixed clocks increases when more and more
domain clocks are added. So, that is why we split out the clock file.
