Just to be clear, the issue is really there, with the psci power
domain, for example.

I am working with an ARM vendor on a platform that has a child node
below the common soc node and which child node is a consumer of the
psci power domain provider node. We fail to get the ->sync_state() to
be called, for reasons that have been explained by now, I think.

The reason for explaining the problem with a superficial example was
to try to easier point out the problem.

That said, I would certainly appreciate your help to get this fixed,
in one way or the other.
