The ordering of power-domains is well defined and there are no holes in it and there are no legacy reasons for having the names (like there are for clocks), so you should drop. This is much like reg-names and I always point people to this message from Rob Herring about reg-names: https://lore.kernel.org/r/CAL_Jsq+MMunmVWqeW9v2RyzsMKP+=kMzeTHNMG4JDHM7Fy0HBg@xxxxxxxxxxxxxx/ You'll have to change your driver to use dev_pm_domain_attach_by_id() but that should be fine. -Doug
