Best it can do is make assumptions of the state the domain was left in by the bootloader. Let the genpd core know of such situations by allowing the providers to specify the state as 'unknown' when the domain gets initialized. Make use of the already exposed enum by adding the 'unknown' option. Then, make all the calls to pm_genpd_init use one of those values. This represents the HW state more accurately and will be helpful for figuring out which unused domain needs to stay powered on until later on.
