To summarize, my main point really is the following: There should not be any need to tag the SoC internal devices with anything in the dts files. The device drivers should be able to just deal with the situation. IMO devices should be tagged with disabled or reserved when they are not accessible for example because of being used by secure mode for example. If the the status needs to be set to anything, it really is a symptom of incomplete handling somewhere. Regards, Tony
