I have kept a separate property since beginning (domain-performance-state) and moved to using these magic values in the existing field because of the suggestion Kevin gave earlier. https://marc.info/?l=linux-kernel&m=149306082218001&w=2 I am not sure what to do now :) > Wouldn't magic values in opp-hz get propagated to user space? The OPP core puts them in debugfs just to know how the OPPs are set. Otherwise, I am not sure that the power domain core/drivers would be exposing that to user space. > I can > see the complaints now. "My 4GHz processor is running at 6Hz!"

I mean, we can clearly add that only power-domains that are managed by firmware are allowed to use magic values here. But not sure if we should put such stuff in bindings. -- viresh -- To unsubscribe from this list: send the line "unsubscribe devicetree" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
