Why? If we have a clear cut semantic that "idle" is for runtime suspend, why should it be a fallback for suspend? You do realize that can just be turned around (as common suspend is more widely implemented than runtime suspend) so that we could say that if "idle" does not exist, we go to "sleep" in runtime suspend. > So, final list of default pnctrl states may be defined as "default", > "active", "idle", "sleep", "off": > - "active", "idle", "sleep": will be handled by omap_device core > - "default", "off": will be handled by driver itself (or Device core). Currently the pinctrl system combines what is called "default" and "active" into one, assuming that all devices shall come up in the active state. Also we haven't seen a device that need some "off" state that is different from "sleep". If you want to drive this state list home you have to give a *real world example*. I want to see a *real* example, for a device and it's pins, that define totally different things for these states, as a rationale. Else we are just defining states to make nice figures or mental maps and that is not helpful for drivers writers.
