So sounds like you don't need any separate "idle" "sleep" and "off" states, the following should do: "default" (or "static") static pins that don't need to be touched after consumer driver probe "active" dynamic pins that are not a subset of "default" needed for runtime; these pins are the same as "idle" below, but with different muxing or pinconf device runtime "idle" dynamic pins that are not a subset of "default" needed for various idle modes; these pins are the same as "active" above, but with different muxing or pinconf for various idle states Can you please confirm that these named modes are enough for your needs? If your hardware does not have specific off mode bits, then I can understand that you may need one mor state "off".
