How does a domain have 2 parent domains? This comes from the early design of the generic PM domain, thus I assume we have some HW with such complex PM topology. However, I don't know if it is actually being used. Moreover, the corresponding DT bindings for "power-domains" parents, can easily be extended to cover more than one parent.
