I think the switching frequency of the DC-DC belongs to the
configuration and don't describe how the hardware is connected. But i
don't have a problem to change it into a DT property.

Does a common property name exists for the switching frequency or would
it be vendor specific?

In the meantime i made some bugfixes on these patches. Now i think it
would be better to integrate the on-chip regulator driver into the patch
series. That would clarify the function of the power driver.
