I don't know what kind of documentation you have. Judging by the question above I think that you are asking me about interpretation of datasheet... Really, your question is very strange... My Exynos5422 datasheet is quite specific on this topic. Anyway you should ask for that to the vendor of the SoC - Samsung LSI. It looks like you are looking for a support which should be given not here, but by the vendor (because they sold you the SoC along with the code). Just to make it clear: I am not related anyhow to the Samsung LSI. I am speaking only for myself. As for the domains, you cannot independently control (under runtime PM) all of the domains. Only some of them. Datasheet explicitly describes what can be controlled. Other stuff is being turned off when entering deeper sleep modes (like AFTR, SLEEP) - you can look for this in cpuidle or suspend related code (open-source or vendor's).
