If you run the dt_bindings_check it should return some errors, as all
these node names should be 'power-domain@'. Which is a bit annoying
because then you will get a bunch of errors like this:

But that's another problem that should be handled in debugfs system.
Indeed...so I chose to use different name in dts to avoid problems in
debugfs. It does violate the naming rules.
But your binding will not pass (or trigger warnings) the dtb check
then. Rob was clear that names should be generic. Proper fix is fix
debugfs not the binding.
By the way, is anybody working on this debugfs issue?
