Assuming I understand correctly, presumably you want to say that it's
required to list _either_ power-domains or supplies.  Right now you
have the bindings saying that you need both regulators and
power-domains on all boards.

Comparing to the patch you posted at
<https://lkml.kernel.org/r/20181127085828.17908-1-sibis@codeaurora.org>,
it seems like maybe you also need "aop" listed here?
