You were kind-of a few days back :) lkml.kernel.org/r/CAL_JsqK-qtAaM_Ou5NtxcWR3F_q=8rmpjum-vqgtkhbtwe5...@mail.gmail.com So here is the deal: - I proposed "domain-performance-state" property for this stuff initially. - But Kevin didn't like that and proposed reusing "opp-hz" and "opp-microvolt", which we all agreed to multiple times.. - And we are back to the same discussion now and its painful and time killing for all of us. TBH, I don't have too strong preferences about any of the suggestions you guys have and I need you guys to tell me what binding changes to do here and I will do that. > If you have firmware > partially managing things, then I think we should have platform specific > bindings or drivers. What about the initial idea then, like "performance-state" for the power domains ? All platforms will anyway replicate that binding only. > This is complex enough I'm not taking silence from Stephen as an okay. Sure, but I am not sure how to make him speak :) -- viresh
