Might be better to define which caches?
I do not expect caches in the same power domain to have different retention capabilities, so a flag per-state should be enough. If anyone is unhappy about this please flag it up. List of caches affected can be retrieved by walking the power-domain specifiers and check those against the caches power domains.
OK, so it's caches located within the power domains referenced by the state node? Might be good to say that say that just for clarity since the power domains are indirected.
