I still don't like having lists of clocks in the power-domain DT. DT is supposed to describe the hardware, and clocks are properties of devices, not power-domains, so the DT description should follow from that. I understand that some device may not be probed etc. when a power-domain needs to transition, but the power-domain driver can still get the list of clocks it needs from the device nodes within the domain, so it shouldn't matter whether devices are probed or not.
